Ammonium sulfide CAS 12135-76-1 yog dab tsi?

Ammonium sulfide yog tam sim no siv dav hauv inorganic sulfide hauv Tuam Tshoj txoj kev lag luam tshuaj. Peb paub tias hnyav hlau sulfides nyuaj rau yaj hauv dej, thiab tseem nyuaj rau yaj hauv cov kua qaub uas tsis yog oxidizing. Los ntawm kev siv hydrogen sulfide los yog soluble sulfides xws li sodium sulfide thiab ammonium sulfide los teb nrog cov hlau ions, insoluble sulfides yuav precipitated los ntawm cov tshuaj.

Daim ntawv thov

Ammonium sulfide tuaj yeem siv los ua chromatographic tsom xam reagent, trace analysis reagent rau thallium, yees duab xim reagent, blackening agent rau mercury thickening method, denitrification agent rau nitrocellulose, tseem ceeb reagent rau tshuaj tsom xam thiab purification ntawm cov tshuaj. Nws kuj tseem siv los ua tus neeg sawv cev rov tsim dua tshiab rau cov pa roj carbon desulfurization hauv kev tsim cov chiv.
