Izimiso Zokukhanya Kwe-X-Ray (I-XRF) Ukuhlaziywa
Ukuhlaziywa kwe-X-ray fluorescence (XRF) kuvusa ama-athomu esampula ngokuwaveza kuma-X-ray anamandla aphezulu. Ama-X-ray ayinhloko akhipha ama-electron angaphakathi kwegobolondo, adala izikhala. Ama-electron avela emagobolondweni aphezulu agcwalisa lezi zikhala, akhulule ama-X-ray angesibili. Into ngayinye ikhipha umunwe ohlukile wama-X-ray angesibili, okuvumela ukuhlonza okuqondile kanye nokulinganisa.
Ukuhlaziywa kwezinto ze-XRF kuhlanganisa izinto kusukela ku-Mg (12) kuya ku-uranium (U, 92). Ukuhlaziywa kwe-XRF yesimanje kuthola ukujiya ezingeni lezingxenye ngesigidi. Izitholi ezithuthukisiwe elabhorethri yokuhlaziya izinto ze-XRF zinikeza imiphumela yokulinganisa kanye neyokulinganisa kungakhathaliseki ukuthi iyinkimbinkimbi kangakanani i-matrix.
Ukuhlolwa kwe-XRF okungabhubhisi kulondoloza isampula. Ukuhlaziywa okuningi kudinga ukulungiswa okuncane noma akukho nhlobo kwesampula. Amathuluzi okuhlaziya e-XRF aphathekayo asekela ukuhlolwa okusheshayo, endaweni. Izinsizakalo ze-XRF spectroscopy kanye nezindawo zokuhlaziya ukwakheka kwamakhemikhali ze-XRF zithembele kulezi zimiso ukuze zithole imiphumela ephezulu nesezingeni lokulandelela.
Izinselele Zemboni Ezixazululwe NguI-XRF
Ukuhlaziywa kwezinto ze-XRF kwenza kube lula ukuhlonza nokulinganisa ama-alloy ensimbi, amaminerali, uketshezi, kanye nophuphu ngemizuzwana. Ukuhlaziywa kwe-X ray fluorescence XRF akubhubhisi futhi kusekela ngqo ukuhlaziywa okusheshayo kwe-XRF chemical composition ngesikhathi sokuqapha inqubo kwezensimbi, ezimayini, kanye nasekusetshenzisweni kabusha.
In i-metallurgy, i-XRF ithola izakhi zezinto eziyisisekelo futhi ilandele amazinga okungcola ezinsimbini ezingagqwali kanye nama-alloy akhethekile. Ubuchwepheshe bamanje be-micro-XRF buxazulula ukusatshalaliswa kwezinto eziyisisekelo ze-3D ezikalini ze-micrometer, okubalulekile ekuchazeni izinto ezithuthukisiwe.
Kwezimayini, abahlaziyi be-XRF abaphathwa ngesandla nabaphathekayo bahlinzeka ngokuhlaziywa kwezinto ze-XRF zezinga lensimu, bemaka izinsimbi ezibalulekile njenge-Ni, i-Cu, kanye nezinto zomhlaba ezingavamile e-ore. Ekusetshenzisweni kabusha, izinhlelo ze-XRF eziku-inthanethi kanye nezindawo zokuhlaziya ze-XRF ziqhuba ukuhlunga, ukunciphisa amaphutha nokuqinisekisa ubumsulwa.
Ukuhlaziywa kwenhlabathi ye-XRF kukhomba izinsimbi ezisindayo njenge-Pb, i-As, ne-Cd emazingeni e-ppm, okusekela ukuqapha kwemvelo kanye nokuhambisana nemithetho. Amalebhu okuhlaziya izinto ze-XRF kanye nokuhlolwa kwe-XRF okungabhubhisi kugcina ubuqotho besampula kuzo zonke izinsizakalo zokuhlaziya insimbi ze-XRF.
I-XRFUbuchwepheshe Bokuhlaziya Nezindawo Zokusebenza
Isikhungo sokuhlaziya sesimanje se-XRF sihlanganisa ama-detector e-multi-element array ukuze kuhlolwe izinto eziyisisekelo ngokushesha nangokusebenzisa amandla aphezulu. Ukuphathwa kwesampula okuzenzakalelayo kusekela ukuhlolwa okuvamile nokwenziwe ngokwezifiso, kuphathwa amakhulu amasampula nsuku zonke.
Amayunithi okuhlaziya e-XRF aphathekayo ahlinzeka ngokuhlolwa kwe-XRF okungabhubhisi izinto eziqinile kanye noketshezi ngqo ensimini. Lawa mathuluzi asekela ukuhlaziywa kwenhlabathi ye-XRF ukuze kuhlolwe ngokushesha izinsimbi ezisindayo kanye nokungcola kwezimboni, ngokuzwela okufika emazingeni e-ppm. Impendulo esheshayo emisebenzini yezimayini kanye nokuvuselela kabusha isheshisa ukuhlunga kanye nokulawula ikhwalithi.
Izinsizakalo ze-XRF spectroscopy zisukela ekuhlolweni okuyisisekelo kuya ekuhlaziyweni okugcwele kokwakheka kwamakhemikhali e-XRF. Amalebhu okuhlaziya izinto ze-XRF azinikele asebenzisa izinsimbi ezisebenza phezulu kanye nezinsimbi ezizenzakalelayo zezinsizakalo zokuhlaziya insimbi ze-XRF ezijulile. Izikhungo zihambisana nezindinganiso zemboni futhi zisekela ucwaningo kuzo zonke izindawo zemvelo, zezimayini, kanye nezokukhiqiza.
Izinzuzo zeI-XRFekuHlaziyweni Kokwakheka Kwezinto Nezamakhemikhali
Ukuhlaziywa kwezinto eziyisisekelo ze-XRF kuthola izinto ezisezingeni lokulandelela ngemizuzwana, kusekela ukuhlolwa kwezinto eziningi kumalebhu aphezulu. I-XRFImisebenzi yelabhorethri yokuhlaziya izinto izuza ekulinganisweni okuthuthukisiwe kanye nehadiwe eqinile, okuqinisekisa imiphumela ephindaphindwayo neyamanani yezinsimbi, inhlabathi, ipulasitiki, noma amaminerali.I-XRFUkuhlolwa kulondoloza ubuqotho besampula ukuze kuhlaziywe okulandelayo, kunciphisa imfucuza futhi kugweme ukwelashwa ngamakhemikhali. Le ndlela idinga ukulungiswa okuncane kwesampula futhi kungabikho ama-reagent, kunciphisa ingozi yokungcola kanye nokwenza lula ukuhamba komsebenzi.I-XRFIzinsizakalo ze-spectroscopy zimboza ububanzi obubanzi bezinto eziyisisekelo kusukela ku-magnesium kuya ku-uranium, okuvumela ukuqedwa okupheleleI-XRFUkuhlaziywa kokwakheka kwamakhemikhali kokubili ocwaningweni kanye nemisebenzi ejwayelekile.I-XRFUkufakwa kwe-analyzer kuvumela ukuhlolwa kwendawo ekumbeni, ekusetshenzisweni kabusha, kanyeI-XRFukuhlaziywa kwenhlabathi, ukuhlinzeka ngempendulo esheshayo kanye nokusekela ukwenziwa ngcono kwenqubo.I-XRFIzinqubo zesikhungo sokuhlaziya zihlangabezana nezimfuneko zomhlaba wonke zokuthobela imithetho, okuhlanganisa i-REACH kanye nemithethonqubo elawula okuqukethwe kwensimbi esindayo emikhiqizweni yabathengi.I-XRFizinsizakalo zokuhlaziya insimbi zikhomba izinto eziyingozi zokubhala imibhalo yokulawula kanye nokulawula ikhwalithi, zisekela ukukhiqizwa okuphephile nokuthobela imithetho.
I-Lonnmeter inikeza uhla oluphelele lwamathuluzi okuhlaziya izakhi ze-XRF, ihlose izinsimbi, inhlabathi, amapulasitiki, kanye namaminerali. Izixazululo eziqondile zivumela ukuhlanganiswa okuqondile nemigqa yokukhiqiza yokuhlaziywa okuqhubekayo kokwakheka kwamakhemikhali e-XRF, ukuhlushwa, ubuningi, i-viscosity, izinga, ingcindezi, kanye nokulinganisa izinga lokushisa. Amathuluzi abhekana nokuqinisekiswa kwe-alloy yensimbi, ukulinganiswa kwe-ore kanye ne-slag, ukutholwa kwezengezo zepulasitiki, kanye nokuhlaziywa kwenhlabathi ye-XRF yokungcola kwensimbi esindayo.
Iminikelo engenziwa ngokwezifiso ifanelana nezidingo zelebhu kanye nezensimu. Abahlaziyi be-XRF abaphathekayo basekela ukuhlaziywa kwe-XRF okusheshayo, okusendaweni kwezinto eziqinile kanye noketshezi ngokulungiselela okuncane kwesampula. Izicelo zelebhu zokuhlaziywa kwezinto ze-XRF zifaka phakathi ukutholwa kwezinga lokulandelela lokulawula ikhwalithi, ukwenza ngcono inqubo, kanye nokuhambisana nomthetho kuzo zonke izimboni zezimayini, zensimbi, zezemvelo, kanye nezepulasitiki.
Cela ikhotheshini yabahlaziyi be-Lonnmeter XRF ukuze babhekane nezidingo zakho zokuhlaziya okuyisisekelo kwe-XRF. Xhumana ne-Lonnmeter ukuthola imininingwane ngezixazululo zokuhlaziya ze-XRF eziphathwayo kanye nokufakwa kwezikhungo zokuhlaziya ze-XRF okulula.
