Ukuhlaziywa kwe-XRF yenhlabathi kwenza ukuhlolwa okusheshayo kanye nokulinganiswa kwezinsimbi ezisindayo ezinobuthi okuhlanganisa i-Pb, i-Cd, i-As, i-Cr, kanye ne-Zn. Ukuhlolwa kwenhlabathi ye-XRF kunikeza ububanzi bokulinganisa obufinyelela ku-ppm, okubalulekile ekuboneni imithombo yokungcola okulandelekayo. Ukulinganiswa okunembile kusekela ukuhambisana nemvelo ngokulinganisa amazinga okungcola ngokumelene nemikhawulo yokulawula. Ukuhlaziywa kwe-XRF kwamasampula enhlabathi kwazisa ukungenelela okusheshayo ngokwenza kube lula ukulungiswa okuhlosiwe ngokusekelwe kumaphrofayili okungcola.
Ukuhlaziywa kokungcola kwenhlabathi kusetshenziswa i-XRF kuletha idatha eqondile yokuhlola ubungozi, kunciphisa ukungaqiniseki ngesikhathi sokuhlela ukulungiswa. Ukuhlaziywa kwenhlabathi ye-XRF ephathekayo kunciphisa ukubambezeleka kokuthatha amasampula, okuvumela ukuhlolwa kwenhlabathi okungabizi kakhulu ezindaweni ezinkulu. Izindlela zokuhlola inhlabathi ye-X-ray fluorescence zihambisana nokuqiniswa kwenqubomgomo ngokuqinisekisa amazinga okungcola kwezicelo zemvume kanye nokuhlolwa kwemvelo.
Izinto Ezingcolisayo Enhlabathini XRF

Ukubuka Konke Kokuhlaziywa Kwenhlabathi Yezimboni ze-XRF
Ukuhlaziywa kwe-Soil XRF kunikeza idatha yesikhathi sangempela, yezinto eziningiukuqapha ukungcoliswa kwezimboniUkuhlolwa kwenhlabathi ye-XRF kulinganisa izakhi ezifaka i-Pb, i-As, i-Cd, i-Cr, ne-Zn ngqo ezindaweni zezimboni. Ukuhlaziywa kwenhlabathi ye-XRF ephathekayo kunciphisa isikhathi sokulungiselela amasampula futhi kukhulisa isivinini sokuqoqwa kwensimu.
Izindlela zokuhlola inhlabathi ye-X-ray fluorescence esetshenziswa ensimini zinikeza imiphumela ephindaphindwayo yokuhlola umthamo omkhulu, okwenza kube ngcono ukusebenza kahle ezindaweni zezimboni. Ukuhlaziywa kwe-XRF yenhlabathi kuqinisekisa ukumepha okusheshayo nokubanzi kokuhlaziywa kokungcola kwenhlabathi kusetshenziswa i-XRF, okubalulekile ekuhlolweni kwezingozi zendawo kanye nokuhambisana nemithetho.
Ukuhlaziywa Kokungcola Kwenhlabathi Kusetshenziswa i-XRF
Ukuhlaziywa kwe-XRF yenhlabathi kuvumela ukutholakala kokugcwala kwezinto ezingaphezulu nangaphansi komhlaba, kufinyelela amazinga okulandelela izinsimbi ezifana ne-Pb, As, Cd, Cr, kanye ne-Zn. Ukuhlaziywa kwenhlabathi ye-XRF ephathekayo kunikeza idatha yesikhathi sangempela, endaweni ngokulinganisa ngqo ukukhishwa kwe-X-ray okubonakalayo okuvela kumasampula enhlabathi.
Izindlela zokuhlola inhlabathi ze-XRF ezisekelwe kugridi zivumela imephu ebanzi yendawo kanye nokukhomba izindawo ezivame ukuphuthelwa yizibonelo zendabuko ezingaphelele. Ukuhlaziywa kwe-XRF kwamasampula enhlabathi kukhiqiza amasethi edatha aqinile ezinto eziningi, abalulekile ekudwebeni ukufuduka kokungcola kanye nokusungula izindlela zokulungisa indawo ethile. Ukuhlanganisa i-XRF nokuhlaziywa kwezakhamzimba zenhlabathi kucacisa kabanzi imithombo yokungcola kanye nokusatshalaliswa. Ukuhlolwa kwenhlabathi yemvelo I-XRF iqinisekisa ukumbozwa okuphelele kokuhlolwa kokungcola kwezimboni kanye nophenyo lokulawula.
Ukuhlaziywa Kwezakhamzimba Zenhlabathi ze-XRFonUkuhlolwa Kokuzala
Ukuhlaziywa kwezakhamzimba zenhlabathi ye-XRF kulinganisa i-K, i-Ca, i-Mg, i-Fe, kanye ne-S iyonke enhlabathini ngesivinini esikhulu kanye nokulungiselela okuncane kwesampula. I-K iyonke kanye ne-Ca ibonisa ukuvumelana okuqinile phakathi kwamasu e-XRF kanye ne-ICP-AES; Amanani e-R² afinyelela ku-0.93–0.98 ye-K kanye no-0.91–0.97 ye-Ca kusetshenziswa ama-algorithms alungisiwe nge-matrix. Izindlela zokuhlola inhlabathi ye-X-ray fluorescence zivumela imephu yokuzala esheshayo nebanzi yendawo kuzo zonke izindawo zezolimo kanye nomhlaba obuyiselwe. Amathuluzi okuhlaziya inhlabathi ephathwayo ye-XRF ahlinzeka ngokulandelela ukuhlukahluka kwezakhamzimba ensimini, okuthuthukisa ukusebenza kahle kokusampula okukhulu.
Ukulungiswa kweCompton kanye nokumodela okungahleliwe kwamahlathi kunciphisa imiphumela ye-matrix yenhlabathi, kuthuthukiswe ukunemba kwe-Mg (R² kufika ku-0.82), i-Fe (R² kufika ku-0.86), kanye ne-S (R² kufika ku-0.78). Idatha ye-XRF isekela ukuhlolwa okuyisisekelo okuthembekile, iqondisa amasu anembile okuguqulwa kwenhlabathi. Ukuhlanganiswa nedatha yedijithali ehambisanayo—ukuthungwa kwenhlabathi, izinto eziphilayo, kanye nomswakama—ngokuhlola inhlabathi yemvelo Izinqubo ze-XRF zithuthukisa ukwenziwa kwezinqumo zezolimo eziphelele. Ukuhlaziywa kwezakhamzimba zenhlabathi ze-XRF kuyisisekelo sokuhumusha imiphumela yokuhlaziywa kwenhlabathi ye-XRF kanye nokwenza ngcono ukuphathwa kwezinsizakusebenza.
Ukuhumusha Imiphumela Yokuhlaziywa Kwenhlabathi ye-XRF
Ukuhlolwa kwenhlabathi ye-XRF kuletha amaphrofayili okuhlushwa kwezinto ku-ppm noma amaphesenti, okuvumela ukuhlolwa komthombo oqondile. Imiphumela evela ekuhlaziyweni kwenhlabathi ye-XRF kumele iqhathaniswe nokuhlushwa kwesizinda sendawo esithile. Iziqondiso ze-EPA zichaza ukungcola kwabantu njengamazinga adlula isizinda sendawo izikhathi ezingu-2-3.
Ukuhlanganiswa kwezinto eziningi (isb., i-Pb, i-Zn, i-Cu) kubonisa imithombo yezimboni noma yasemadolobheni, kuyilapho izinto ezingaphandle kwezinto eyodwa eduze kwamaphuzu emisebenzi aziwayo ziqokomisa ukungcoliswa okuqondile. Izilinganiso zezinto ezifana ne-Pb:Zn zibonisa izimpawu zomthombo—ngokusobala ukuthi zibangelwa abantu uma ziphambuka ku-geology yesifunda.
Ukuhlaziywa kwendawo kusetshenziswa amamephu okushisa noma ukuboniswa kwe-GIS kwembula izindawo ezishisayo kanye nezindlela zokufuduka. Ukwenzeka kanyekanye kokungcola, izitayela zendawo, kanye nokuhlaziywa kwezibalo (ukuqoqana, i-PCA) kuchaza imvelaphi yabantu uma kuqhathaniswa ne-geogenic. Ukubika okulawulwayo kudinga imibhalo ephelele yokunqunywa kwesizinda, ukukhethwa komkhawulo, kanye nezinqubo zokuhumusha idatha, okusekela ukuhambisana nemvume yokuhlolwa kwenhlabathi yemvelo i-XRF.
Kungani Kufanele Ukhethe Abahlaziyi be-Lonnmeter XRF
I-LonnmeterIsihlaziyi senhlabathi se-XRFinikeza umthamo ophezulu, ilinganisa ngokunembile izakhi ezinhlobonhlobo ze-matrices zenhlabathi. Njengoba kunemikhawulo yokuthola ku-sub-ppm yokungcola okubalulekile, kufaka phakathi i-Pb, i-As, i-Cd, i-Cr, ne-Zn, lawa mathuluzi asekela ukuhlaziywa kwe-XRF yenhlabathi esezingeni lokulawula kanye nokuhlolwa okusheshayo komthamo omkhulu.
Izivalo eziqinile zivikela izingxenye ukuze zisebenze ezimweni ezinzima zezimboni nasensimini, zigcina ukunemba naphezu kokungcola, umswakama, noma ukushintsha kwezinga lokushisa. Ukwakheka kwedivayisi okuqinile kweLonnmeter kwenza ukusetshenziswa okuqhubekayo kokuhlaziywa kwenhlabathi ye-XRF ephathekayo kanye nokulinganisa okuqondile ngaphandle kwesikhathi sokungasebenzi. Imiphumela yesikhathi sangempela kanye nokuqina kunciphisa umthwalo womsebenzi webhubhoratri futhi kusekela ukwenza izinqumo ngokushesha zokuhlaziywa kokungcola kwenhlabathi kusetshenziswa i-XRF.
Isixhumi esibonakalayo somsebenzisi esilula nesiqondakala kalula sisheshisa izindlela zokuhlola inhlabathi ye-X-ray fluorescence, senza abasebenzi bakwazi ukuhumusha imiphumela yokuhlaziywa kwenhlabathi ye-XRF endaweni. Ukusekelwa okuphelele kobuchwepheshe kanye nokusetshenziswa kusiza ukuhlanganisa abahlaziyi be-Lonnmeter nemisebenzi ekhona yokuhlolwa kwenhlabathi kwemvelo ye-XRF kanye nemisebenzi yokuhlaziywa kwezakhamzimba zomhlaba.
Cela ikhotheshini eyenzelwe wena yabahlaziyi be-Lonnmeter XRF ukuze kube lula ukuhlaziywa kwe-soil XRF yakho futhi kuqinisekiswe ukuhambisana nemithetho yezimboni. Bonke abahlaziyi be-Lonnmeter XRF bahlangabezana nezindinganiso eziqinile zokuhlaziywa kokungcoliswa kwenhlabathi yensimbi esindayo besebenzisa i-XRF.
