Nws tuaj yeem ua haujlwm los tshem tawm cov khoom hnyav hlau los ntawm cov dej khib nyiab los ntawm adsorption lossis nag lossis daus. Kev tshawb fawb txuas ntxiv mus tshawb fawb txog kev ua tau zoo ntawm ntau hom hlau 2 sulfide hauv cov ntawv thov no. Kev ua tau zoo thiab tus nqi-zoo yog qhov tseem ceeb ntawm kev txiav txim siab nws txoj kev siv dav dav.

Kev Tiv Thaiv Kev Nyab Xeeb Thaum Tuav Hlau 2 Sulfide

Hlau 2 sulfide nthuav tawm qee yam kev nyab xeeb, feem ntau yog vim nws cov tshuaj tiv thaiv acids thiab nws lub peev xwm rau oxidation. Kev sib cuag ncaj qha nrog cov kua qaub tuaj yeem ua rau kev tso tawm cov pa roj carbon monoxide thiab flammable hydrogen sulfide, tsim kom muaj qhov cua thiab cov cuab yeej tiv thaiv tus kheej (PPE). Tsis tas li ntawd, raug nplua hlau 2 sulfide hmoov av tuaj yeem ua rau ua pa ua pa. Yog li, cov txheej txheem tuav tsim nyog, suav nrog kev siv lub tshuab ua pa thiab hnab looj tes, yog qhov tseem ceeb.

Synthesis ntawm Hlau 2 Sulfide

Hlau 2 sulfide tuaj yeem ua ke los ntawm ntau txoj hauv kev, suav nrog cov tshuaj tiv thaiv ncaj qha ntawm hlau thiab sulfur nyob rau hauv kev tswj xyuas. Lwm txoj kev koom nrog cov tshuaj tiv thaiv ntawm cov ntsev hlau nrog sulfide qhov chaw hauv kev daws. Lub purity thiab crystalline qauv ntawm qhov tshwm sim hlau 2 sulfide tuaj yeem sib txawv heev nyob ntawm seb txoj kev xaiv thiab cov tshuaj tiv thaiv tsis zoo. Cov txheej txheem synthesis meej yog feem ntau haum rau cov ntawv thov tshwj xeeb.

Kev sib piv ntawm cov ntawv sib txawv ntawm Iron Sulfide

Muaj ntau hom hlau sulfide, nthuav tawm cov khoom sib txawv thiab kev siv. Cov lus hauv qab no muab ib qho kev sib piv luv luv ntawm qee cov yam ntxwv tseem ceeb.

Nco tseg: Cov ntaub ntawv no tsuas yog siv rau kev kawm nkaus xwb. Nco ntsoov sab laj cov ntaub ntawv kev nyab xeeb (SDS) thiab cov kev cai cuam tshuam ua ntej tuav hlau 2 sulfide los yog lwm yam tshuaj.
