Lwm yam siv
♦ Hauv kev lag luam kev yees duab los tiv thaiv cov kev daws teeb meem los ntawm oxidation.
♦ Nws yog siv rau hauv kev tsim cov tshuaj roj hmab thiab lwm yam tshuaj sib xyaw.
♦ Nws yog siv rau lwm yam kev siv xws li ore flotation, roj rov qab, zaub mov preservative, ua dyes, thiab detergent.
Sodium hydrosulfide yog cov tshuaj sib xyaw nrog cov mis NaHS.Cov tshuaj no yog cov khoom ntawm ib nrab-neutralization ntawm hydrogen sulfide (H2S) nrog sodium hydroxide.NaHS thiab sodium sulfide yog siv hauv kev lag luam, feem ntau rau cov laj thawj zoo sib xws.Khoom NaHS tsis muaj xim.Cov khoom muaj ntxhiab H2S vim hydrolysis los ntawm atmospheric noo noo.Nyob rau hauv sib piv nrog sodium sulfide (Na2S), uas yog insoluble nyob rau hauv cov organic solvents, NaHS, yog ib tug 1: 1 electrolyte, yog ntau soluble.
HAIV NEEG THIAB KEV RUAJ NTSEG
