Chifukwa Chake Kuyesa kwa Lead Pamalo Ogwirira Ntchito N'kofunika Kwambiri
Kupezeka ndi lead kumabweretsa kutayika kwa ndalama zokwana $6 thililiyoni padziko lonse paumoyo ndi zachuma chaka chilichonse, ndipo imfa za anthu akuluakulu 5 miliyoni za mtima zimagwirizanitsidwa ndi kuipitsidwa chaka chilichonse. Ana okhala m'mizinda ndi m'mafakitale amataya mfundo zochulukirapo za IQ kuchokera ku lead ndi 80% kuposa momwe ananenera kale. Utsi wochokera m'mafakitale, dothi losatha komanso loipitsidwa likadali magwero opezeka paliponse.
Mfuti zoyesera za XRF zonyamulika zimapereka kuchuluka kwa lead m'nthaka, fumbi, ndi zinthu zadothi pamalopo, kuchepetsa nthawi yotayika yotumizidwa ku labotale ndikupangitsa kuti pakhale mapu ofulumira a zoopsa m'nyumba, masukulu, ndi malo opangira zinthu asanafike 1978.Zowunikira za XRFKuti mupeze ma lead, chotsani zolakwika zabodza. Zinthu zophatikiza deta zimathandiza zolemba zenizeni kuti zichotsedwe pamalopo, chitetezo cha ogwira ntchito, komanso kuwunika kokonzanso. Kuyika zinthu zenizeni kukuwonetsa kuti oyesa ma lead a XRF m'manja amatha kuyika ma geo-tag masauzande ambiri a miyeso tsiku lililonse, zomwe zimapangitsa kuti kukonza kukhale kosavuta komanso kuteteza thanzi la anthu ammudzi.

Alangizi azachilengedwe amakumana ndi kusatsimikizika kosalekeza pankhani ya lead m'magawo ovuta amunda. Malo ambiri ali ndi zigawo za utoto wopakidwa isanafike komanso pambuyo pa 1978, ndipo mulingo wosadziwika wa lead umafunika kufufuzidwa bwino. Akatswiri okonza zinthu ayenera kuzindikira ndikulemba kuti akutsatira zofunikira zochepetsera lead pogwiritsa ntchito mfuti yoyesera ya xrf m'malo osiyanasiyana: makoma amkati, dothi la malo osewerera, ndi chitsulo chopakidwa utoto.
Akatswiri a ukhondo wa mafakitale amayang'anira malo ogwirira ntchito komwe kuipitsidwa kwa mpweya ndi pamwamba kumasinthasintha. Miyezo yolamulira ya lead—monga 400 ppm pa nthaka—imalola mwayi wochepa woti pakhale zolakwika pazida. Kuti akwaniritse nthawi yofotokozera malipoti, ogwiritsa ntchito amafunika chowunikira cha xrf chonyamulika cha lead chomwe chimayesa nthaka pamalopo ndi kutulutsa kotsimikizika nthawi yomweyo. Kuchedwa kapena deta yosasinthasintha kuchokera ku ntchito zachikhalidwe za FAAS kapena ICP-AES zochokera ku labu zimavuta kuwongolera mtengo komanso kutsatira malamulo.
Oyang'anira malo amakumana ndi kukakamizidwa kuti apereke malipoti mwachangu asanakonzedwe, kubwereka, kapena kugwiritsidwa ntchito ndi anthu onse. Kusonkhanitsa zitsanzo pamanja ndi kusanthula labu nthawi zambiri kumawonjezera masiku ku nthawi ya polojekiti.Oyesa ma lead a xrf ogwidwa ndi manjaMonga Lonnmeter, chepetsani nthawi yogwira ntchito, pezani njira yosavuta, ndikulola kutumiza mwachindunji deta yotheka kwa owongolera ndi makasitomala. Kutha kupereka chiwonetsero cha utsogoleri pamalopo, posankha bwino ndi chipangizo chowunikira cha xrf tsopano ndi chiyembekezo choyambirira.
Momwe XRF Analyzers Amapezera Lead Molondola
Zoyezera za XRF zonyamulika, monga mfuti yoyesera ya Lonnmeter xrf, zimazindikira kuchuluka kwa lead mu zinthu zolimba kuphatikiza dothi, fumbi, mafupa, ndi madontho a magazi ouma kudzera mu X-ray fluorescence. Poyezera pamwamba, chipangizochi chimayambitsa wosanjikiza woonda wa chitsanzo (nthawi zambiri 1-2 mm) ndikulemba ma X-ray odziwika bwino. Pazinthu zambiri—monga ma pellets a nthaka okanikizidwa kapena zigawo zokhuthala—kuyeza kumawonetsa bwino matrix yonse ya chitsanzo.
Chowunikira cha Lonnmeter xrf chowunikira kuti chizindikire lead chimapeza kukhudzika kwa kutsata, kuwerengera kuchuluka kwa lead m'mafupa pamlingo wa ppb ndi m'nthaka pa ppm, chofunikira kwambiri pakuwunika nthawi yayitali komanso kuchitapo kanthu pazigawo zoyenera.
Kulondola ndi kulondola kumadalira kulinganiza kokhwima pogwiritsa ntchito miyezo yovomerezeka, pamodzi ndi kusintha kwa zotsatira za matrix ndi kusuntha kwa zida. Kafukufuku akutsimikizira kuti njira zowongolera ndi kukonza tsankho ndizofunikira kwambiri—tsankho losakonzedwa lingayambitse kusiyana kwakukulu pankhani ya malire azamalamulo, makamaka pazida zozikidwa pa radioisotope ndi chubu.
Zinthu Zofunika Kwambiri za Mfuti Yoyesera ya Lonnmeter XRF Lead
Mfuti yoyesera ya Lonnmeter xrf imapereka kunyamulika kwenikweni ndi chassis yolimba, yopepuka yochepera 30 cm ndipo imalemera zosakwana 2 kg. Moyo wa batri umaposa maola 8 ndi nthawi yofulumira yochapira. Kapangidwe kake ka ergonomic kamaphatikizapo chogwirira chozungulira ndi mawonekedwe a touchscreen, zomwe zimathandiza kugwira ntchito ndi dzanja limodzi m'malo ogwirira ntchito otsekedwa. Zolumikizira zachitetezo ndi masensa oyandikira zimaletsa kuwonekera mwangozi panthawi yowunikira pamwamba.
Liwiro lopeza lead m'nthaka ndi lochepera masekondi 30 pa muyeso uliwonse, ndipo kukhudzidwa kwa labotale kwatsimikiziridwa ndi mayeso a CDC soilSHOP. Kuwerenga kwa digito nthawi yomweyo kumathandiza kuyesa gulu ndi kupanga zisankho nthawi yeniyeni m'malo omwe ali ndi mphamvu zambiri. Kubwerezabwereza, kuberekanso, ndi malire ozindikira zimatsimikiziridwa kudzera muzipangizo zovomerezeka komanso njira zowongolera khalidwe. Chisankho cha zida za Lonnmeter chikupitirirabe pansi pa 5% RSD kudutsa malire olamulira a lead.
Dongosolo lolumikizirana la chipangizochi limalola kutumiza zotsatira mwachindunji ku CSV kapena PDF kuti zilembedwe patsamba ndikutsatira malamulo. Kulemba deta kumathandiza kulemba malo, ma ID a zitsanzo, ndi nthawi yokhazikika kuti zitsatidwe bwino. Njira zosagwiritsa ntchito njira zokonzera zitsanzo zimathandiza kusanthula mwachindunji zinthu zadothi, kapena nthaka popanda kuwonongeka kapena kugwiritsa ntchito mankhwala oopsa. Chitetezo cha wogwiritsa ntchito chimakulitsidwa kwambiri ndi kutchingira kumapeto ndi kuyimirira yokha ikakhala yopanda ntchito.
Kukulitsa Kulondola ndi Kudalirika pa Kuwunika Lead
Chowunikira chilichonse cha xrf chonyamulika cha lead chimafuna kuyesedwa koyamba kwa fakitale ndi zida zovomerezeka, kutsatiridwa ndi kutsimikizika kwa tsiku ndi tsiku kapena pakusintha pogwiritsa ntchito ma check plates kapena miyezo. Kukonzanso kwathunthu ndi kukonza ma drift kumasunga zotsatira mkati mwa ± 5% ya mtengo wotsimikizika, kuthandizira malire a zochita zoyang'anira omwe adakhazikitsidwa ndi malangizo a EPA ndi HUD. Zida zosayang'anira xrf lead zosakonzedwa bwino kapena zosakonzedwa bwino nthawi zonse zimapangitsa zolakwika zoyezera kupitirira 20% ya mtengo weniweni, zomwe zimapangitsa kuti pakhale kuphwanya malamulo ndi kulephera kukonza.
Makhalidwe a zitsanzo amakhudza mwachindunji muyeso. Kuchulukana, makulidwe, ndi kufanana kwa zinthu zoyesera kungayambitse kusiyana kwa mayankho a XRF. Mwachitsanzo, chitsanzo chokhuthala, chokhala ndi lead yambiri chingakhudze chowunikira, pomwe chitsanzo cha nthaka yosagwirizana chingapereke kuwerenga kochepa komanso kosagwirizana. Zotsatira za matrix zimafuna miyezo yogwirizana ndi matrix kuti muchepetse kusagwirizana, makamaka pakusokoneza kwa calcium kapena chitsulo.
Mayendedwe antchito amafuna chitsimikizo chapamwamba kwambiri. Ogwiritsa ntchito Lonnmeter handheld xrf lead tester amalemba ma check calibration, kusunga zolemba pa shift iliyonse, ndikuwongolera momwe zinthu zilili. Zipangizo zonse zoyesera xrf lead ziyenera kuphatikizapo mayeso okhazikika opanda kanthu, kuwerenga kobwerezabwereza, ndi kugwiritsa ntchito miyezo yovomerezeka yowongolera. Zotsatira zakunja kwa kulekerera kwa khalidwe zimayambitsa kukonzanso mayeso asanayambe mayeso ena. Kudalirika kwakukulu kwa zotsatira kumachokera pakuphatikizira ma check olembedwa ndi mapulogalamu, ma protocol athunthu a QA, ndi machitidwe oyenera ogwiritsira ntchito zitsanzo pa xrf analyzer iliyonse yowunikira ma lead.
Momwe Mungasankhire Mfuti Yoyenera Yoyesera ya XRF Lead
Kusankha mfuti yabwino kwambiri yoyesera lead ya xrf kumafuna kusamala kwambiri pa malire ozindikira, liwiro losanthula, ndi kunyamulika. Chipangizo chowunikira cha lead xrf chapamwamba kwambiri chimapereka zotsatira zosakwana masekondi 30 pamalo aliwonse, chofunikira kwambiri pakuwunika kwakukulu pakukonzanso ndi kuwunika katundu.
Kapangidwe ka ergonomic ndi kunja kolimba kumaonetsetsa kuti choyezera cha xrf chogwiritsidwa ntchito m'manja chimakhala chodalirika pamikhalidwe yamunda, pomwe ma touchscreen ndi mawonekedwe osavuta kugwiritsa ntchito amachepetsa zofunikira pamaphunziro. Choyezera cha xrf chonyamulika cha Lonnmeter cha lead chimaphatikiza GPS yomangidwa mkati, kutumiza deta ya batch, ndi zidziwitso zowunikira nthawi yeniyeni. Ogwiritsa ntchito amapindula ndi masensa oyandikira kuti achepetse kuwonekera kwa radiation kosafunikira.
Musanagule, funsani za njira zowerengera, chithandizo chautumiki, kupezeka kwa magawo ena, ndi mfundo za chitsimikizo.
