Ithini isishwankathelo sokwahlulwa kwe-sodium hydrosulfide?
i-sodium hydrosulfide Isiphelo
Le ndlela iqala ngokwahlula iityuwa zekristale ezifana neNa₂CO₃ kwisisombululo seNaHS esixineneyo. I-NaHS·H₂O enyibilikisiweyo emva koko iqina ngokuthe ngqo ibe ziiflakes kwi-vacuum rake cooler ngaphambi kokuba ipakishwe ngokuzenzekelayo. Ngenxa yoko, umxholo wokungcola we-Na₂CO₃ wehlisiwe ukusuka kwi-2.4% ukuya kwi-0.3%. Inkqubo yokupholisa yenzeka kwindawo engenamoya, inciphisa i-oxidation ngenxa yokuvezwa komoya kwaye ithintela ngokufanelekileyo ukuwohloka kwemveliso. Yonke inkqubo yokucoca yenziwa kwinkqubo evaliweyo, ithintela ukukhutshwa kweegesi ezicaphukisayo kwaye ithintela ungcoliseko lwendalo olungemva. Iiflakes ze-NaHS sodium hydrosulfide zipakishwa ngqo, zisusa ungcoliseko ngexesha lokugcina. Ukongeza, le ndlela ilula, ayifuni zixhobo zininzi, kwaye ixabisa kancinci.
