He mea nui te tātaritanga huānga oneone mō te whakaora ā-umanga, te tutuki i ngā ture, te haumaru o te tāone, me te ahuwhenua tauwhiro. Mā te whakamātautau oneone XRF ka taea te ine tere i ngā konganuku taumaha, tae atu ki te Pb, Hg, As, Cd, Cr, Ni, me te Cu, hei whakahaere tika i ngā mōrearea i ngā wāhi poke. He mea nui te tātaritanga matūkai tika—e kapi ana i te hauota, te whākawa, me te pāhare pāporo—hei whakapai ake i ngā hua o te hua me te whakaiti i ngā para tongi.
Ngā Tikanga Tātari Oneone XRF Matua
Mā te whakamātautau oneone XRF ka whakamahia te tirotiro XRF hei tautuhi i ngā tapumati huānga i roto i ngā matrices oneone. Ka pupuhihia e te taputapu ngā tauira oneone ki ngā hihi-X tuatahi, ka tukuna e ngā ngota o ia huānga ngā photon hihi-X tuarua motuhake ki taua huānga. Mā te kimi me te ine i ēnei tukunga ka taea te ine i ngā huānga maha, tae atu ki ngā konganuku, ngā metalloids, me ngā matūkai matua.
Tātari Huānga Ahumahi
*
Mā ngā tikanga tātari oneone XRF ka taea te ine i te nui o ngā huānga katoa. Ko te kaha o te hihi-X i inehia e pā tika ana ki te kukū huānga. Ka tātarihia e te XRF he whānuitanga o ngā huānga mai i te konutai ki te uranium. Kei roto i ngā whakatakotoranga tauira ko ngā paura wetewete, ngā pirepire pēhia, me ngā tauira matua kāore i pakaru. Ka taea e ngā taputapu XRF taiwhanga me ngā taputapu kawe te tātari oneone taiao i te wāhi me te wāhi.
Ka tautokohia e te tikanga ngā tauira matihiko kanorau me te iti o te whakarite, ā, ka mau tonu te kaha whakaputa nui mō ngā tono ahumahi me te taiao. Ko te tika e whakawhirinaki ana ki te whakatikatika me te whakatikatika i te makuku oneone, te rahi o te matūriki, me te rerekētanga.
Ngā Pūrere Whakamātautau Oneone XRF Kawe
Mā ngā taputapu whakamātautau oneone XRF kawe ā-ringa ka taea te kimi tika i ngā kukū huānga i roto i te mara me te takiuru raraunga whakauru me te GPS. He pakari ngā waeine mō ngā āhuatanga ahumahi me te taiao uaua. Mā te whakarite tauira iti ka taea te tere te whakatakoto ki ngā whenua rerekē. Ka tātarihia e ngā taputapu ngā poke matua, tae atu ki te mata (Pb), te mercury (Hg), te arsenic (As), te cadmium (Cd), te chromium (Cr), te nickel (Ni), te parahi (Cu), me ngā matūkai nui.
Ka whakahaerehia e ngā kaiwhakahaere mara ngā tikanga tātari oneone XRF i roto i ngā hēkona ki ngā meneti mō ia tauira, e tautoko ana i te whakamātautau konganuku taumaha oneone wā-tūturu XRF me te tātari oneone taiao XRF. Mā te kitenga maha-huānga, kore-whakangaro ka taea te tātari anō, te tāruarua rānei me te kore e ngaro te pono o te tauira. Mā te whakamātautau oneone XRF kawe ka tutuki te hononga tae atu ki te 85–95% (R²) me ngā hua taiwhanga mō ngā konganuku pēnei i te Pb, As, me te Cd.
Ngā Hua o te Whakamātautau Oneone XRF
Mā te whakamātautau oneone XRF ka puta ngā raraunga huānga i te wāhi e tangohia ai te tauira, ka taea ai te whakatau tonu i te wāhi. Ka whakaitihia te huringa tātari ki ngā hēkona, ki te whakaritea ki ngā rā mō ngā tikanga taiwhanga tuku iho. Ka whakakorehia e ngā tikanga tātari oneone XRF te roa o te tuku tauira me te roa o te rarangi taiwhanga, ka tautoko tika i ngā mahi tutuki i ngā whakaritenga i roto i ngā rangahau oneone ahumahi me ngā rangahau oneone tāone.
Ka heke ngā utu mahi nā te mea he iti ake ngā kaimahi e hiahiatia ana mō te kawe tauira, mō te whakahaere taiwhanga rānei. Ko ngā tauira kua tohua, kāore rānei i te mārama, me mahi taiwhanga i muri mai, ka tino whakaiti i ngā whakapaunga tātari. Mā ngā taputapu whakamātautau oneone XRF kawe ka taea te kapi i ngā wāhi nui, ka tere te tuhi raraunga me te mahere ā-wāhi e hangai ana ki te GPS. Ka tohua e te whakamātautau oneone ā-tūnga mā te whakamahi i te XRF ngā wāhi wera o te poke, ka arotau i te kōwhiringa oneone mō te whakaora kua tohua, ka whakaiti i ngā utu whakakorenga.
Ko te tika o te tātaritanga e whakawhirinaki ana ki te whakatauritenga o te tauira me te whakatikatika mā te whakamahi i ngā oneone tohutoro kua whaimana. Tērā pea he teitei ake ngā rohenga kitenga mō te Cd me te Hg i te Pb, i te As rānei; ka whakamahia ngā tauwehenga whakatikatika mō ngā whāriki oneone uaua. Ka tautokohia e ēnei tikanga whakamātautau oneone XRF matatau te tātari oneone taiao XRF i raro i ngā kawa whakahaere mō te aroturuki me te manatoko whakaora.
Me pēhea te whakamahi i te XRF mō te tātari oneone
Kohia ngā tauira oneone e whakaatu ana i te āhua o te oneone mā te whakamahi i te koko, te taputapu tauira matua, te auger rānei. Whakakotahitia ngā tauira hei whakaiti i te rerekētanga o te wāhi; whakaranua kia pai, ka huri kia rite te āhua ina taea. Whakamarokehia ki te hau, whakamarokehia rānei ki te oumu i raro i te 60°C kia rite ai ngā pānui XRF; ka rerekē nui ngā hua i te makuku.
Tātarihia te oneone maroke mā roto i tētahi mata whatu 2 mm, mā roto rānei i tētahi mata angiangi ake hei whakataurite i te rahi o te matūriki, hei whakarei ake i te auautanga me te tika o te whakamātautau oneone XRF. Mō te tātari ā-tūnga, tangohia ngā paru mai i te wāhi ine i mua i te whakatakotoranga o te taputapu. Whakatakotoria ngā taputapu whakamātautau oneone XRF kawe ki runga i te mata o te oneone, whakakīia rānei ngā kapu tauira ki ngā rauemi kua whakaritea tika.
Te Tika o te Whakamātautau Oneone XRF
E whakaū ana ngā rangahau arotake-ā-hoa he tino tika te whakamātautau oneone XRF mō ngā matūkai me ngā poke konganuku taumaha. He maha ngā kaupapa rangahau e whakaatu ana i ngā taunga taunga (R²) o te 0.84 neke atu rānei mō ngā matūkai nui pēnei i te konupūmā me te pāhare pākawa ina whakamahia te whakatauira matatau me te whakatikatika tika, tae atu ki te whakataurite Compton me te whakatauira tapawhā iti rawa. Ko te tino tika o te horahanga mō te whakamātautau poke oneone me te XRF ka eke ki te R² = 0.998 mō ngā huānga pēnei i te Pb, As, me te Zn, e whakamanahia ana e ngā inenga ex situ ki ngā rauemi tohutoro kua whakamanahia. Ko ngā tikanga tātari oneone XRF kawe ka mahi tonu i runga i te rite ki ngā tikanga taiwhanga mō te ihirangi huānga katoa. Mā te whakauru i ngā raraunga āwhina—te kakano oneone, ngā raraunga vis-NIR, me ngā pānuitanga anō—ka whakapai ake i te tika o te whakamātautau oneone XRF, inā koa mō ngā tauira matatini. Ko te tātari oneone taiao Ko ngā tikanga XRF me ngā tikanga whakamātautau oneone XRF matatau kei te noho pono tonu mō te whakamātautau oneone in-situ mā te whakamahi i te XRF puta noa i ngā oneone me ngā poke rerekē.
Aromatawai Taiao me ngā Matūkai
Mā te whakamātautau oneone XRF ka taea te tātari i ngā matūkai nui me ngā poke konganuku taumaha i roto i ngā oneone ahuwhenua me te māra. Ka inehia e ngā tikanga tātari oneone XRF ngā matūkai nui pēnei i te K, Ca, me ngā huānga iti i roto i te matawai kotahi, e tautoko ana i ngā rautaki whakamomona tika. E ai ki ngā rangahau arotake-ā-hoa, ka taea e R²≥0.84 te ine i te Ca me te K ahakoa i roto i ngā oneone rerekē. Ka tere ngā hua o ngā taputapu whakamātautau oneone XRF kawe i roto i te wāhi, e āwhina ana i ngā whakarerekētanga motuhake ki te wāhi mō te whakahaere whenua pumau. Ka piki ake te pono me te tika o te whakamātautau i roto i ngā whāriki uaua e ngā painga o te whakamātautau oneone XRF.
Ka tautokohia e ngā tauira ringaringa, e whakamahia ana e te pākahiko te mahere wā-tūturu, te whakamātautau oneone i roto i te wāhi mā te whakamahi i te XRF, me te tuku raraunga mō te tutuki i ngā whakaritenga me te rangahau o te wāhi.Contact Lonnmeter hei whakatutuki i ngā hiahia tātari uaua me te whakamātautau oneone XRF kua whakamātauhia.
