amakuru

1. gushonga mumazi hamwe na lye ya dilute, nyuma yo guhagarara kugirango bisobanurwe, igisubizo cyo hejuru cya lye cyibanze cyane kugirango kibone sodium sulfide ikomeye. Tablet (cyangwa granule) ibicuruzwa bya sodium sulfide biboneka binyuze mu kigega cyohereza, kumeza (cyangwa granulation)
Ikigereranyo cyimiti igereranya: Na2SO4 + 2C → Na2S + 2CO2

2.Uburyo bwo gukoresha: 380-420 g / L sodium hydroxide yumuti ikoreshwa mugukuramo imyanda irimo H2S> 85% hydrogène sulfide, kandi ibicuruzwa byabonetse bihumeka kandi bigashyirwa hamwe kugirango haboneke sodium sulfide ibicuruzwa byarangiye.
Ikigereranyo cyimiti igereranya: H2S + 2NaOH → Na2S + 2H2O

3. Uburyo bwa Barium sulfide, sodium sulfide irashobora kuboneka nkibicuruzwa mugihe sodium sulfate na barium sulfide ikoreshwa muguhindura metathesis kugirango hategurwe barium sulfate yaguye. Ibyo
Ikigereranyo cya reaction ya chimique: BaS + Na2SO4 → Na2S + BaSO4 ↓

4. kuboneka. ~ 97%).
Ikigereranyo cya reaction ya chimique:
Na2SO4 + 4CO → Na2S + 4CO2
Na2SO4 + 4H2 → Na2S + 4H2O

5.Uburyo bwo kubyara, uburyo bwo gutunganya bukoresha sodium sulfide yumuti hamwe nibice 4% byibicuruzwa mugihe cyo kubyara barium sulfate yaguye nkibikoresho fatizo. Nyuma yo kuyijugunya mumashanyarazi abiri yingaruka kugirango ihumeke kugeza 23%, yinjira mubigega bikurura kugirango ikureho icyuma. , Nyuma yo kuvanaho karubone, lye isunikwa mumashanyarazi (ikozwe mubintu bya nikel isukuye) kugirango ihumure lye kugirango igere kumurongo, hanyuma yoherezwa mumashini ya tablet yo gukonjesha amazi yingoma.

Uruganda rwacu rukoresha uburyo bubiri, uburyo bwo kugabanya amakara hamwe nuburyo bwa barium sulfide, kugirango butange sodium sulfide itukura na flake yumuhondo.
