Yini isifinyezo sokuhlukaniswa kwe-sodium hydrosulfide?

isodiyamu ye-hydrosulfide Isiphetho
Indlela le ithoma ngokuhlukanisa amatswayi afana ne-Na2CO3 ukusuka esixazululweni se-NaHS esihlanganisiweko. I-NaHS · H Njengomphumela, ukungcola kwe-Na2CO3 kwehliswa kusuka ku-2.4% ukuya ku-0.3%. Ikambiso yokupholisa yenzeka ngaphakathi kwe-vacuum, ukunciphisa ukukhiqizwa kwe-oksijini ngebanga lokuvezwa komoya begodu kuvimbele ukuwohloka komkhiqizo. Ikambiso yoke yokuhlanza yenziwa ngendlela evaliweko, ukukhandela ukukhutjhwa kwamagesi acasulako nokugwema ukusilaphazeka kwebhoduluko kwesibili. I-NaHS sodium hydrosulfide flakes zipakishwa ngqo, ukususa ukusilaphazeka ngesikhathi sokugcina. Phezu kwalokho, indlela le ilula, itlhoga iinsetjenziswa ezincani, begodu ayibizi.

I-sodium hydrosulfide ithunyelwa emazweni amanengi, ngeentengo eziphakemeko nokuthunyelwa okurhabako. Tlika lapha ukuthola izimanga.
