Ukusatshalaliswa kosayizi wezinhlayiya zomhlabathi kubumba ukuhanjiswa kwamanzi, ukuqina, kanye nesakhiwo sezimbobo. Amajika okugcina amanzi ayashintsha njengoba izingxenyana zesihlabathi, udaka, kanye nobumba zihluka; inhlabathi yesihlabathi ikhipha amanzi ngokushesha, inikeza umswakama olinganiselwe, kuyilapho inhlabathi yobumba igcina amanzi kodwa ivimbela ukungena komoya. Inhlabathi ye-loam inikeza ukutholakala kwamanzi okulinganiselayo, isekela ukukhula kwezimpande okuhle kakhulu kanye nokumuncwa kwezakhamzimba. Ukungafani kwe-granulometric kuthinta amandla okushintshana kwe-cation kanye ne-micro-porosity, kulawula ukuhamba kwezakhamzimba. Kwezolimo, ubukhulu bezinhlayiya zomhlabathi buthinta ngqo ukuzala futhi buthinta amasu okulungisa. Amakilasi osayizi bezinhlayiya anquma ukulula kokwakhiwa, okuthinta amandla okuthwala kanye nokugeleza kwamanzi.

Ukubaluleka kwe-Rubidium Element enhlabathini
Ukuhlushwa kwe-Rubidium kubonisa ukwakheka kwenhlabathi kanye nokwakheka kwamaminerali. Njengophawu lokulandelela, i-rubidium ihambisana ne-feldspar kanye ne-mica, eningi emadwaleni e-siliceous. Ukusatshalaliswa kwayo kubonisa ukubuswa kwezinto zomzali; inhlabathi ye-siliceous ivame ukubonisa amazinga aphezulu e-rubidium, okusiza ukuhlukaniswa kokuthungwa. Ukuba khona kwe-Rubidium kusekela izifundo zemvelaphi kanye nokulandelela kwemvelo ekuhlaziyweni kwenhlabathi. Ukuhlukaniswa kokuthungwa kwenhlabathi ngobukhulu bezinhlayiya, kuhlanganiswe nemephu ye-rubidium, kucwengisisa ukuhlonza izinto zomzali wenhlabathi futhi kwazisa ukuhlaziywa kokwakheka kwezinto eziyisisekelo kusetshenziswa izinsimbi ze-XRF.
I-Rubidium njengesibonakaliso sobukhulu bezinhlayiya zomhlabathi
I-Rubidium ivame ukugxila kumaminerali e-feldspar kanye ne-mica, alawula izinto eziyinhloko ze-siliceous parent materials. Inhlabathi ye-siliceous ibonisa ukuhlushwa kwe-rubidium kusuka ku-20 kuya ku-150 mg/kg, ngokuguquguquka okukhulu kwendawo okuhlobene nokuqina kwesimo sezulu kanye namaphrofayili amaminerali. Enhlabathini ye-limestone, amazinga e-rubidium awavamile ukudlula u-50 mg/kg, okubonisa ukuba khona okulinganiselwe kwamaminerali e-felsic kanye nezizinda ze-geochemical ezihambisanayo. Ukwehluka kwe-rubidium kuhambisana ngokucacile nezinga lokuguqulwa kwamaminerali kanye nezinto eziyinhloko zenhlabathi eziyinhloko, okusekela ukusetshenziswa kwayo njengophawu oluqinile lokwakheka.
Indlela Amazinga e-Rubidium Abikezela Ngayo I-Granulometry Yomhlabathi
Ukuhlushwa kwe-rubidium kuhlobene ngqo nezingxenyana zobukhulu bezinhlayiya enhlabathini ye-siliceous. Izingxenyana ezincane njengobumba nodaka zigcina i-rubidium ephezulu ngenxa yendawo yamaminerali kanye nokuqukethwe kwe-mica, kanti izingxenyana zobumba zivame ukwedlula i-100 mg/kg enhlabathini ye-siliceous. Izingxenyana zesihlabathi esiqinile zibonisa i-rubidium ephansi, ikakhulukazi enhlabathini etholakala enhlabathini ye-limestone. Izilinganiso ze-XRF, eziqinisekiswe yiI-Lonnmeter I-EDXRF, kuvumela ukulinganiswa okusheshayo kulo lonke ububanzi bosayizi wezinhlamvu, okwenza kube lula ukuhlukaniswa kokuthungwa kwenhlabathi kanye nokumapha ngokusebenzisa imisebenzi eqinile ye-geostatistical. Ukuhlaziywa kwedatha okubanzi kuqinisa inani le-rubidium kumamodeli okubikezela ukusatshalaliswa kosayizi wezinhlayiya zenhlabathi ezifundweni zezolimo nezemvelo.
Ukubhekana Nobukhulu Bezinhlayiya Zenhlabathi kanye Nezimo Ezihlukahlukene Zokuqukethwe Kwemvelo
Usayizi wezinhlayiya kanye nokwehluka kokuqukethwe kwezinto eziphilayo kunethonya elincane kakhulu ekulinganisweni kwe-XRF rubidium. Izifundo zakamuva zifakazela ukuthi ukubandlulula kokulinganisa akunamsebenzi enhlabathini enosayizi wokusanhlamvu ophakathi kuka-20 µm no-2 mm kanye nokuqukethwe kwezinto eziphilayo okungaphansi kuka-12%. Ukulinganisa ngokumelene nenhlabathi ebhekiselwe kuyo kuqhubeka nokuthuthukisa ukunemba, kusekela ukuhlukaniswa kwezinto eziyinhloko zenhlabathi okuthembekile kanye nokuhlolwa kokuthungwa.
I-Lonnmeter XRF Soil Analyzer: Izici kanye Nezicelo
I-Lonnmeter XRF Soil Analyzer isebenzisa ubuchwepheshe obuthuthukisiwe be-EDXRF, ifinyelela imikhawulo yokuthola i-rubidium ephansi njenge-1 ppm futhi ixazulula izinsimbi zokulandelela ezibalulekile zingakapheli imizuzwana engama-60. Izitholi ezinesinqumo esiphezulu zisekela ukuhlaziywa kosayizi wezinhlayiya zenhlabathi ngokulinganisa i-rubidium kanye nezimpawu zezinto eziyisisekelo ezihlobene kumasampula aqinile. Yakhelwe ukusetshenziswa kwensimu okuqinile, idivayisi inesisindo esingaphansi kwama-2 kg futhi imelana nokushintshashintsha kwezinga lokushisa kusuka ku--10°C kuya ku-45°C, okuvumela ukufundwa kwezinto eziyisisekelo okunembile ezindaweni ezahlukahlukene.
Ukuhumusha Idatha ye-XRF yobukhulu bezinhlayiya zomhlabathi
Hlanganisa ama-readout e-rubidium XRF namakilasi osayizi wezinhlayiya atholakala kusihluzo/i-hydrometer yendabuko noma amamodeli aqinisekisiwe ukuze uqinise ukuhlukaniswa kokuthungwa kwenhlabathi. Beka ama-fraction osayizi wezinhlayiya kuma-concentration e-rubidium; ama-fraction e-silt+clay enhlabathini ye-siliceous avame ukukhombisa amazinga aphezulu kakhulu e-rubidium. Sebenzisa izindlela ze-geostatistical ukuze wembule izitayela zendawo kanye nokungafani. Ukuhlolwa kwe-high-throughput ngama-analyzer e-XRF aphathekayo kusheshisa ukuhlolwa kwesikali sendawo ukuze kuhlukaniswe ukuthungwa kwenhlabathi ngobukhulu bezinhlayiya.
Izilinganiso Ezihambisanayo Zokuhlela Iphrofayili Yomhlabathi Ogcwele
Ngasikhathi sinye linganisa izakhamzimba ezinkulu (i-K, i-Ca, i-Mg) kanye nezinsimbi ezincane/ezisindayo (i-Zn, i-Pb, i-Cr) ngokukhishwa kwe-spectral ye-XRF, uqinisekise ukuhlaziywa okuphelele kokwakheka kwenhlabathi kusetshenziswa i-XRF kanye nomongo wezinhlobo zezinto ezisizayo zomhlaba kanye nokwakheka kwazo. Ezifundweni zemvelo, hlanganisa ukuchazwa kosayizi wezinhlayiya kanye nokuhlolwa kwensimbi esindayo ukuze uhlole ithonya lezinto ezisizayo zomhlabathi ekuvundeni komhlaba kanye nengozi yokungcola.
Cela Isilinganiso seLonnmeter XRF Soil Analyzer
I-Lonnmeter XRF Soil Analyzer ihlanganisa i-EDXRF ephathekayo nokutholwa okuthuthukisiwe kwe-rubidium. Ilungiselelwe ngokukhethekile ukuhlukanisa ukusatshalaliswa kosayizi wezinhlayiya zenhlabathi kwezolimo, ukuhlola ukuhlukaniswa kokwakheka kwenhlabathi ngobukhulu bezinhlayiya, kanye nokusekela izifundo ngezinhlobo zezinto zomzali wenhlabathi kanye nokwakheka kwayo.
Xhumana nochwepheshe bezobuchwepheshe ukuze uthole imibhalo ngezidingo zesampula, ukuhlela ukuboniswa, noma amanani aklanyelwe ngokusekelwe ekuhlanganisweni kwensimu noma kwelebhu. I-analyzer ihlangabezana nezidingo zezindlela zokuhlaziya inhlabathi ze-XRF ezisheshayo kanye nezicelo, abahlaziyi be-XRF abaphathwayo abajwayelekile bokuhlolwa kwenhlabathi, kanye nemisebenzi ephelele yokuhlolwa kwenhlabathi kanye nobuchwepheshe bokuhlaziya.
imibuzo ejwayelekile ukubuzwa
Buyini ubudlelwano phakathi kwe-rubidium nosayizi wezinhlayiya zomhlabathi?
Ukuhlushwa kwe-Rubidium kulandelana nokusatshalaliswa kohlobo lwamaminerali. Izinto zomzali we-siliceous—ezicebile ngama-feldspar nama-micas—zibonisa i-rubidium ephezulu neguquguqukayo. Izingxenyana zenhlabathi ezincane zivame ukubonisa i-rubidium ekhulayo ngenxa yesimo sezulu esikhethekile kanye nokwakheka kwamaminerali obumba, okuvumela ukusetshenziswa kwayo njengesivikelo sokuhlukaniswa kokuthungwa kwenhlabathi ngobukhulu bezinhlayiya.
Ukuhlaziywa kwenhlabathi ye-XRF kuhluke kanjani ezindleleni zendabuko?
Ukuhlaziywa kwenhlabathi ye-XRF kudala ukuhlaziywa kokwakheka kwenhlabathi okunezakhi eziningi kusetshenziswa i-XRF ngemizuzu embalwa, ukuze kutholakale izinto eziqinile ezomile nezifanayo. Akukho ukugaya noma ukukhipha amakhemikhali okudingekayo, ngokungafani nezindlela zendabuko ze-wet chemistry.
Ingabe ukuhlaziywa kwe-XRF kuyasebenza ekutholeni ukungcola kwenhlabathi kanye nosayizi wezinhlayiya?
Yebo. I-XRF ilinganisa i-rubidium, ezinye izakhi ze-alkali, kanye nokungcola okufana ne-Pb, i-Cd, i-As, kanye ne-Zn ngokuskena okukodwa. Abahlaziyi be-XRF abaphathekayo bokuhlolwa kwenhlabathi basekela ukuhambisana nemithetho kanye nokulungiswa kwesayithi ngendlela engcono kakhulu.
