Sodium cyanide yog siv ua lag luam rau fumigation, electroplating, extracting kub thiab nyiaj los ntawm ores, thiab tshuaj manufacturing.

Hais txog qhov no, dab tsi yog sodium cyanide siv rau hauv kev lag luam mining?

A sodium cyanide kev daws yog feem ntau siv mus leach kub los ntawm ore. Heap leaching: Hauv qhov qhib, cyanide kev daws yog sprayed tshaj loj heaps ntawm crushed ore kis atop loj sau pads. Cov cyanide dissolves kub los ntawm cov ore mus rau hauv cov tshuaj raws li nws trickles los ntawm lub heap.

Ib sab saum toj no, qhov txawv ntawm sodium cyanide thiab potassium cyanide yog dab tsi? Sodium thiab poov tshuaj cyanide yog ntsev, uas yog khov. Zyklon B yog lub ntiaj teb diatomaceous permeanted nrog hydrogen cyanide . Cov tshuaj lom ib feem ntawm cyanide yog cov cyanide anion. Dab tsi cov anion txuas nrog tsis yog qhov tseem ceeb yog toxicity.

Ib sab saum toj no, sodium cyanide ua li cas?

Ntau lawm thiab cov khoom siv tshuaj lom neeg Sodium cyanide yog ua los ntawm kev kho hydrogen cyanide nrog sodium hydroxide: HCN + NaOH → NaCN + H2O. Sodium cyanide reacts sai nrog muaj zog acids kom tso hydrogen cyanide . Cov txheej txheem txaus ntshai no sawv cev rau kev pheej hmoo tseem ceeb cuam tshuam nrog cyanide ntsev.

Dab tsi yog cov ntsiab lus hauv sodium cyanide?

Formula thiab qauv: Cov tshuaj formula ntawm sodium cyanide yog NaCN, thiab nws cov molar loj yog 49.01 g / mol. Nws yog ib qho ionic compound tsim los ntawm cov sodium kev (Na+) thiab cyanide anion (CN-), nyob rau hauv uas cov carbon muaj ib tug triple daim ntawv cog lus nrog cov nitrogen atom.
