Txheej txheem cej luam khoom:
Nickel yog ib hom hlau dawb-nyiaj uas muaj cov qauv tawv thiab tawg yooj yim. Nws tseem ruaj khov hauv huab cua ntawm chav sov thiab yog ib qho khoom tsis tshua muaj zog. Nickel ua rau cov tshuaj tiv thaiv yooj yim nrog nitric acid, thaum nws cov tshuaj tiv thaiv nrog dilute hydrochloric lossis sulfuric acid qeeb dua. Nickel tshwm sim ntuj hauv ntau yam ores, feem ntau ua ke nrog sulfur, arsenic, lossis antimony, thiab feem ntau yog los ntawm cov zaub mov xws li chalcopyrite thiab pentlandite. Nws yuav muaj nyob rau hauv cov dej khib nyiab los ntawm kev khawb av, smelting, alloy ntau lawm, ua hlau, electroplating, tshuaj lom neeg, nrog rau ceramic thiab iav tsim.Lub tshuab ntsuas no muaj peev xwm ua haujlwm tau yam tsis tas yuav siv tes ua haujlwm ntev raws li qhov chaw teeb tsa. Nws siv tau dav rau kev saib xyuas cov dej khib nyiab uas tawm hauv kev lag luam, cov dej khib nyiab los ntawm kev lag luam, cov dej khib nyiab los ntawm cov chaw kho dej khib nyiab hauv kev lag luam, thiab cov dej khib nyiab los ntawm cov chaw kho dej khib nyiab hauv nroog. Nyob ntawm qhov nyuaj ntawm cov xwm txheej kuaj hauv qhov chaw, lub kaw lus ua ntej kho tuaj yeem teeb tsa tau los xyuas kom meej tias cov txheej txheem kuaj txhim khu kev qha thiab cov txiaj ntsig raug, ua tau raws li qhov xav tau ntawm ntau qhov xwm txheej hauv thaj chaw.
Cov Ntsiab Cai Khoom:
Cov khoom no siv txoj kev ntsuas spectrophotometric. Tom qab cov qauv dej sib xyaw nrog tus neeg sawv cev buffer, thiab nyob rau hauv qhov muaj tus neeg sawv cev oxidizing muaj zog, nickel raug hloov mus ua nws cov valence ions siab dua. Nyob rau hauv qhov muaj cov tshuaj buffer thiab ib qho qhia, cov valence ions siab dua no ua rau muaj cov xim sib xyaw. Lub tshuab tshuaj ntsuam xyuas pom qhov kev hloov pauv xim no, hloov qhov sib txawv mus rau hauv tus nqi nickel concentration, thiab tso tawm cov txiaj ntsig. Qhov ntau ntawm cov xim sib xyaw tsim tawm sib raug rau qhov concentration nickel.
