Ibara ry'umutuku rya Cadmium ni ubwoko bw'amabara adafite umwimerere agizwe n'ibisubizo bikomeye bya cadmium sulfide (CdS) na cadmium selenide (CdSe). Ingano nyayo ya selenium (x) ni yo igena ibara, igahindura ibara kuva kuri orange (low Se) ikajya kuri red (high Se) mu kugabanya icyuho kuva kuri 2.4 eV (pure CdS, umuhondo) kikagera kuri 1.7 eV (pure CdSe, umutuku).
Kumenya ibara mu buhanzi biragoye bitewe n'ibipimo bya selenium na cadmium bitandukanye, imiterere ifatika, n'amabara asa neza n'andi mabara atukura. Uburozi bwa selenium n'ingano ya metal ikomeye bituma habaho igenzura rikomeye ry'amategeko. Isesengura ry'imiterere y'irangi neza rishyigikira kubahiriza amategeko, umutekano, n'ubuziranenge bw'ibirango.

Amahame ya XRF Spectroscopy mu gusesengura ibara ry'uruhu
Ishusho ya X-ray fluorescence (XRF) ikora ku buryo atome ziri muri cadmium itukura ikoresheje X-rays y’ibanze, igasohora electron z’imbere. Atome iraruhuka isohora X-rays ya kabiri (fluorescent) ifite ingufu zihariye. Ku buryo bwo gusesengura ibara ry’ibinyabutabire, Kα na Kβ bya selenium biba kuri 11.2 na 12.5 keV, uko bikurikirana; cadmium igaragara kuri 23.1 keV. XRF yemerera gusesengura imiterere y’ibinyabutabire by’ibinyabutabire bitagize ingero zangiza. XRF itanga uburyo bwo kumenya ibara ry’ibinyabutabire n’ibinyabutabire, ikamenya ingano ya selenium kugeza ku bice kuri miliyoni muri matrices yumye. Kumenya bibaho mu masegonda, bigatuma habaho ikarita y’imiterere y’ibinyabutabire bigoye mu kubungabunga ubuhanzi cyangwa mu rwego rwo kwemeza ubuziranenge.
Ibyiza by'ingenzi of XRF Spectroscopy inPigment CompositiyoniAnaurumuriis
XRF ihura n'ibisabwa mu gukoresha irangi ritukura rya cadmium, yirinda gupima ibintu bike bikenerwa n'uburyo nka ICP-OES cyangwa AAS. Ugereranije n'uburyo bwo kumenya irangi ryangiza, XRF ibika ingero za kera n'iza none, ishyigikira uburyo bwo kumenya irangi mu kugenzura cyangwa gusuzuma umutekano w'irangi. XRF ikora neza ku bice bikomeye byasizwe irangi, irangi ry'ifu, n'ibintu bidafite aho bihuriye, bigatuma hakorwa isesengura ryimbitse ry'imiterere y'irangi no gukurikirana uburozi bwa seleniyumu mu mirimo itandukanye no mu nganda zitandukanye.
Isuzuma ry'ubwiza n'ingano bya Selenium mu mabara y'umutuku ya Cadmium
XRF ituma hamenyekana neza selenium mu ibara ritukura rya cadmium binyuze mu kubona imisozi itandukanye ya selenium Kα (11.2 keV) na Kβ (12.5 keV). Kuba hariho imirongo yombi ya cadmium Kα (23.1 keV) na selenium Kα byemeza ko ibara rigizwe n'imiterere ya cadmium sulfo-selenide.
Gupima ibikumwe bya XRF bitandukanya ibara ry'umutuku rya cadmium n'umuhondo wa cadmium sulfide cyangwa andi mabara y'umutuku adafite selenium. Ku mvange cyangwa impinduka, uburyo bwo gukoresha imiterere y'ibara ryuzuye n'isesengura rya chimiometric (urugero, isesengura ry'ibice by'ingenzi) byongera itandukaniro, bigagabanya ingaruka mbi mu kumenya amabara mu bicuruzwa by'ubukorikori cyangwa mu nganda.

Abasesenguzi ba Lonnmeter XRF bapima cadmium, selenium, n'ibindi byuma by'ingenzi bya pigment mu bipimo bikomeye, ifu, n'amabara yasizwe. Igihe cyo gusesengura kiri hagati y'amasegonda 30 kugeza70amasegonda. Ubushobozi bwo hejuru bwo gusuzuma imiterere ya spectral n'uburyo bwo gupima umusaruro bugezweho bukwiriye gusesengura imiterere ya color no kugenzura ikoreshwa rya cadmium red pigment na selenium pigments. Interface ya ecran ikoresha ecran ifasha ubuhanga bwo kumenya color hamwe n'uburyo bwateguwe mbere, ecran igaragara, na raporo z'ibizamini zishobora guhindurwa. Amakuru ashobora koherezwa hanze binyuze kuri USB cyangwa Wi-Fi. Gufata ingero byakira ifu ikaranze, ibintu bikomeye bihuye, cyangwa irangi ry'urutonde; ntabwo ari ngombwa gutegura ingero zangiza. Gufunga umutekano w'imirasire y'imbere n'igishushanyo gito (<2 kg zikoreshwa mu ntoki) zituma habaho ibikorwa bitekanye kandi bifatika.
Sicyuma gipima ikirere gikoresha icyuma cya silikoniof Isesengura rya XRF rya Lonnmeter rishyigikira uburyo bwihuse kandi bunoze bwo gusesengura ibara ry’ibinyabutabire hamwe no kongera gupima. Ibiranga uburyo bwo gusesengura ibara birimo gusuzuma imiterere yaryo n’uburyo bwo kumenya ibara bujyanye n’ubuhanzi, inganda, n’imikorere y’ubushakashatsi.
Gusaba Igiciro n'Intambwe zikurikiraho
Uru rubuga rutanga inama zishingiye ku bisabwa mu ikoreshwa ryarwo, harimo ikoreshwa rya cadmium itukura, uburozi bwa selenium, n'uburyo bwo gusesengura imiti ya shimi. Serivisi zo kugisha inama ziyobora uburyo bwo guhindura sisitemu zigoye za color cyangwa kubahiriza amabwiriza agenga umutekano w'irangi. Imiterere yose irimo uburyo bwo gufata ingero bujyanye n'ifu, utubumbe twakaswe, n'ibikoresho byasizwe irangi.
Gutegura neza ikoreshwa ry’ibikoresho bikubiyemo gutegura ingero, guhitamo ibikoresho byemewe, n’uburyo busanzwe bwo kumenya ibara ry’uruhu. Ubufasha bukomeje burimo gusubiramo ibikoresho kugira ngo habeho isesengura ry’imiterere y’ibara ry’uruhu, gukemura ibibazo by’urusaku ruke cyangwa urusaku rwinshi, hamwe n’amabwiriza y’umutekano yo gucunga ibara rya cadmium na selenium.
Ibibazo Bikunze Kubazwa
Ibara ry'umutuku rya cadmium ni iki kandi seleniyumu igira uruhare rungana iki mu miterere yaryo?
Ibara ry'umutuku rya Cadmium ni cadmium sulfoselenide, igizwe na cadmiumsulfidena 10–25% cadmium selenide. Iyoni za selenium ziba ahantu hakozwe mu buryo bwa lattice, zigahindura ibara kuva kuri orange kugeza kuri red fluid binyuze mu guhindura ikigereranyo cya CdS:CdSe. Matrix ya crystalline ituma habaho imbaraga nyinshi zo guhanga ibara no kudahinduka. Selenium yongera ibara kandi igakomeza kuramba, ikaba ingenzi cyane ku mabara y’abahanga ahoraho kandi adahindagurika ndetse n’ibikoresho by’inganda.
Ni gute XRF spectroscopy ifasha mu kumenya ibara ry'uruhu?
Isuzuma rya XRF rigaragaza cadmium na selenium mu buryo butaziguye mu matrikisi y’ibara rikomeye kugira ngo habeho isesengura ry’ibinyabutabire bya pigment ritangiza. Ibice by’ingenzi, birimo cadmium Kα (23.2 keV) na selenium Kα (11.2 keV), bituma hamenyekana vuba imiterere y’ibara. Ubu buryo butandukanya neza ibara rya selenium n’andi moko, aho imipaka yo kurimenya iri munsi ya 50 ppm bitewe n’imiterere ya matrikisi n’imiterere y’icyitegererezo.
Kuki kumenya ingano ya seleniyumu mu marangi ari ingenzi?
Gusuzuma ingano ya seleniyumu birakenewe kugira ngo habeho umutekano w'irangi, imikorere ihamye, no kubahiriza amabwiriza mpuzamahanga ku bidukikije n'iy'abakozi. Seleniyumu nyinshi yongera ibyago byo kwangirika kw'irangi kandi igira ingaruka ku kongera kubyara. Imiterere ya seleniyumu igenzurwa igenzura igenzura ko amategeko akurikizwa kandi igakora neza mu buhanga,gusigana pulasitiki.
