Isesengura ry’ibice by’ubutaka ni ingenzi cyane mu gusana inganda, kubahiriza amategeko, umutekano mu mijyi, no mu buhinzi burambye. Gupima ubutaka bwa XRF bituma hapimwa byihuse ibyuma biremereye, birimo Pb, Hg, As, Cd, Cr, Ni, na Cu, kugira ngo habeho gucunga neza ingaruka mu duce twanduye. Isesengura ry’intungamubiri rikwiye—rikubiyemo azote, fosifore na potasiyumu—ni ingenzi cyane mu kunoza umusaruro w’ibihingwa no kugabanya imyanda y’ifumbire.
Ubuhanga bwo gusesengura ubutaka bwa Core XRF
Isuzuma ry’ubutaka rya XRF rikoresha spectroscopy ya XRF kugira ngo hamenyekane ibikumwe by’ibanze biri mu bipimo by’ubutaka. Icyo gikoresho gitera ingero z’ubutaka hakoreshejwe imirasire ya X y’ibanze, bigatuma atome za buri gice zisohora fotoni za X-ray za kabiri zihariye kuri icyo gice. Gupima no gupima iyi myuka bituma hapimwa ibintu byinshi, harimo ibyuma, metalloids, n’intungamubiri z’ingenzi.
Isesengura ry'ibice by'inganda
*
Ubuhanga bwo gusesengura ubutaka bwa XRF butanga igipimo cy’ibintu byose. Ubukana bwa X-ray fluorescence bujyanye neza n’ubwinshi bw’ibintu. XRF isesengura ubwoko bwinshi bw’ibintu kuva kuri sodiyumu kugeza kuri uranium. Imiterere y’icyitegererezo irimo ifu yoroheje, utubumbe twakaswe, n’ibipimo by’ibanze bitarangirika. Ibikoresho bya laboratwari n’ibigendanwa bya XRF bifasha gusesengura ubutaka mu bidukikije aho biri no mu bidukikije aho biri.
Ubu buryo bushyigikira ingero zitandukanye hamwe n’itegurwa rito, kandi bukomeza ubushobozi bwo gukoresha neza mu nganda no mu bidukikije. Ubuziranenge bushingiye ku gupima no gukosora ubushuhe bw’ubutaka, ingano y’uduce, n’ubutandukanye.
Ibikoresho byo gupima ubutaka bya XRF bitwarwa
Ibikoresho byo gupima ubutaka bya XRF bifatwa n'intoki bitanga uburyo bwo kumenya neza ingano y'ibintu mu murima hifashishijwe uburyo bwo kubika amakuru hamwe na GPS. Ibikoresho bikozwe mu buryo bukomeye mu rwego rw'inganda n'ibidukikije. Gutegura ingero nke bituma habaho kwihuta mu butaka butandukanye. Ibikoresho bisesengura ibintu by'ingenzi birimo icyuma cy'ubutare (Pb), mercure (Hg), arsenic (As), cadmium (Cd), chromium (Cr), nickel (Ni), umuringa (Cu), n'intungamubiri z'ingenzi.
Abakora mu mirima bakora tekiniki zo gusesengura ubutaka za XRF mu masegonda kugeza ku minota kuri buri gipimo, bashyigikira isuzuma ry’icyuma gikomeye cy’ubutaka mu buryo bw’igihe nyacyo XRF n’isesengura ry’ubutaka ku bidukikije XRF. Gusuzuma ibintu byinshi bidasenya bituma isesengura risubirwamo cyangwa rigasubirwamo nta gutakaza ubuziranenge bw’icyitegererezo. Isuzuma ry’ubutaka rya XRF rigendanwa rigera ku kigero cya 85–95% (R²) hamwe n’ibisubizo bya laboratwari ku byuma nka Pb, As, na Cd.
Ibyiza byo gupima ubutaka bwa XRF
Gupima ubutaka bwa XRF bitanga amakuru y’ibanze aho hafatwaga ingero, bigatuma hafatwa ibyemezo byihuse aho hantu. Guhindura isesengura bigabanuka kugeza ku masegonda, ugereranije n’iminsi yo gukoresha uburyo gakondo bwo muri laboratwari. Ubuhanga bwo gusesengura ubutaka bwa XRF bukuraho igihe cyo kohereza ingero n’igihe cyo gutondeka umurongo muri laboratwari, bigashyigikira mu buryo butaziguye ibikorwa byo kubahiriza amategeko mu bushakashatsi bw’ubutaka mu nganda no mu mijyi.
Ikiguzi cy'abakozi kiragabanuka kubera ko hakenewe abakozi bake mu gutwara cyangwa mu gutunganya laboratwari. Ingero zigaragara gusa cyangwa zidasobanutse neza zisaba akazi ka laboratwari gakurikiraho, bigabanya cyane amafaranga akoreshwa mu gusesengura. Ibikoresho byo gupima ubutaka bya XRF byorohereza gukwirakwira mu bice binini, bitanga amakuru yihuse no gukora ikarita y'ahantu hifashishijwe GPS. Gupima ubutaka muri ako gace hakoreshejwe XRF bipima ahantu hashobora kwanduza, bigatuma ubutaka butoranywa neza kugira ngo bukosorwe, ibyo bigatuma ikiguzi cyo kubujugunya kigabanuka.
Ubunyangamugayo bushingiye ku guhuza ingero n'uburyo zikoreshwa hakoreshejwe ubutaka bwemewe. Imipaka yo kumenya Cd na Hg ishobora kuba iri hejuru ugereranyije na Pb cyangwa As; ibintu byo gukosora bikoreshwa ku buryo bugoye bwo gupima ubutaka. Ubu buryo bugezweho bwo gupima ubutaka bwa XRF bushyigikira isesengura ry'ubutaka bushingiye ku bidukikije XRF hakurikijwe amabwiriza y'ikigo yo gukurikirana no kugenzura ubuziranenge bw'ubutaka.
Uburyo bwo gukoresha XRF mu gusesengura ubutaka
Kusanya ingero z'ubutaka ukoresheje agakoresho ko gupima, icyuma gipima imiterere, cyangwa icyuma gipima. Hindura ingero kugira ngo ugabanye ubusumbane bw'ahantu; vanga neza hanyuma usya kugeza ku ifu imwe igihe bishoboka. Ingero zumutse mu kirere cyangwa zumye mu ifu ziri munsi ya 60°C kugira ngo ubone ingero za XRF zihamye; ubushuhe buhindura cyane ibisubizo.
Shyira ubutaka bwumye mu mashini ifite ubugari bwa mm 2 cyangwa imashini ntoya kugira ngo umenye neza ingano y'uduce, ibyo bikaba byongera ubushobozi bwo gusubiramo no gukora neza mu isuzuma ry'ubutaka rya XRF. Kugira ngo usuzume aho hantu, kura ibisigazwa by'ubutaka mu gace gapimirwa mbere yo gushyiramo igikoresho. Shyira ibikoresho byo gupima ubutaka bya XRF ku butaka cyangwa wuzuze ibikombe by'icyitegererezo ibikoresho byateguwe neza.
Ubuziranenge bw'isuzuma ry'ubutaka rya XRF
Ubushakashatsi bwasuzumwe n'urungano bwemeza ko isuzuma ry'ubutaka rya XRF rigera ku buziranenge bwo hejuru ku ntungamubiri ndetse n'ibintu byanduye by'icyuma kiremereye. Imishinga myinshi y'ubushakashatsi ivuga ko coefficients (R²) nibura 0.84 ku ntungamubiri z'ingenzi nka kalisiyumu na potasiyumu iyo hakoreshejwe icyitegererezo gihanitse no gupima neza, harimo normalizing ya Compton na partial least square regression. Ubuziranenge bw'ubuso bwo gupima ubwandu bw'ubutaka hakoreshejwe XRF bugera kuri R² = 0.998 ku bintu nka Pb, As, na Zn, nk'uko byemejwe n'ibipimo bya ex situ ugereranije n'ibikoresho byemewe. Ubuhanga bwo gusesengura ubutaka bwa XRF buhora bukora neza nk'uburyo bushingiye kuri laboratwari ku bipimo byose by'ibintu. Guhuza amakuru y'inyongera - imiterere y'ubutaka, amakuru ya vis-NIR, n'ibisomwa bisubirwamo - binoza cyane uburyo bwo gupima ubutaka bwa XRF, cyane cyane ku bipimo bigoye by'ingero. Isesengura ry'ubutaka ku bidukikije Uburyo bwa XRF n'uburyo buhanitse bwo gupima ubutaka bwa XRF bikomeje kuba ingirakamaro mu gupima ubutaka buri ahantu hatandukanye hakoreshejwe XRF mu butaka butandukanye n'ibintu byanduye.
Isuzuma ry'ibidukikije n'imirire
Gupima ubutaka bwa XRF bituma habaho gusesengura icyarimwe intungamubiri z'ingenzi n'ibintu byanduza ibyuma bikomeye mu butaka bw'ubuhinzi n'ubuhinzi. Ubuhanga bwo gusesengura ubutaka bwa XRF bupima intungamubiri nka K, Ca, n'ibice bito mu isuzuma rimwe, bishyigikira ingamba zo gufumbira neza. Ubushakashatsi bwasuzumwe n'urungano bugaragaza R²≥0.84 ku gupima Ca na K ndetse no mu butaka butandukanye. Ibikoresho byo gupima ubutaka bya XRF bitwara bitanga ibisubizo byihuse aho biri, bikorohereza ivugurura ryihariye ry'ahantu kugira ngo ubutaka bukomeze gukoreshwa. Inyungu zo gupima ubutaka bwa XRF zongerera icyizere no gukora neza isuzuma mu buryo bugoye.
Uburyo bwo gukoresha bateri bukoreshwa n'intoki bushyigikira ikarita mu gihe nyacyo, gupima ubutaka aho buherereye hakoreshejwe XRF, no kohereza amakuru kugira ngo harebwe niba aho hantu hakurikizwa ibisabwa kandi hakorwa ubushakashatsi.Contact Lonnmeter kugira ngo ikemure ibibazo bikomeye byo gusesengura hakoreshejwe isuzuma ry’ubutaka rya XRF ryagaragaye.
