Kev siv

Ib qho zoo heev txog sodium cyanide yog nws txoj kev siv dav hauv kev ua liaj ua teb. Nws cov khoom xyaw nquag ua rau nws zoo heev hauv kev tswj thiab tshem tawm cov kab tsuag uas ua rau muaj kev hem thawj rau cov qoob loo thiab cov nroj tsuag. Tsis tas li ntawd, sodium cyanide plays lub luag haujlwm tseem ceeb hauv kev lag luam kub mining thiab refining kev lag luam. Vim nws muaj peev xwm yaj kub, nws yog dav siv nyob rau hauv lub extraction thiab purification ntawm no precious hlau.

Tsis tas li ntawd, qhov no multifunctional compound ua raws li ib qho tseem ceeb daim npog qhov ncauj thiab complexing neeg sawv cev thaum lub sij hawm tshuaj synthesis. Nws cov khoom tshwj xeeb tso cai rau nws ua rau muaj kev cuam tshuam nrog lwm cov tshuaj los tsim cov complexes ruaj khov uas yog qhov tseem ceeb hauv ntau yam tshuaj tiv thaiv. Tsis tas li ntawd, sodium cyanide yog siv nyob rau hauv electroplating, kom ntseeg tau tias cov hlau ua ib tug du, txawm txheej rau ntau yam ntawm qhov chaw.

Hauv cov ntsiab lus, Sodium Cyanide yog qhov sib xyaw zoo kawg nkaus uas ua lub luag haujlwm tseem ceeb hauv kev lag luam sib txawv. Nws cov khoom zoo heev xws li dej solubility thiab yooj yim ntawm kev siv ua rau nws zoo tagnrho rau ntau yam kev siv. Txawm hais tias ua kom zoo nkauj kub, tswj cov kab tsuag, lossis siv los ua tus neeg sawv cev complex, sodium cyanide tau ua pov thawj tias yog ib qho cuab yeej txhim khu kev qha thiab tseem ceeb. Nrog nws cov kev siv ntau yam, qhov sib xyaw ua ke tseem yog ib qho khoom muaj txiaj ntsig hauv thaj chaw ntawm cov tshuaj synthesis thiab cov txheej txheem kev lag luam.
