Improvement on Determination of the Components of Industrial Sodium Polysulfide

Abstract:

The analytical method on sodium sulfide, sodium sulfite, sodium hydroxide and sodium thiosulfate in sodium polysulfide solution was studied in this paper. The questions in concealing sodium sulfite by formaldehyde and precipitating sodium sulfide by zine acetate, a common method reported in some papers before, was discussed. The improvement on concealing Na2SO3 by SrCl2 instead of formaldehyde and precipitating Na2S by Zn(OH)2 instead of Zn(Ac)2 and testing concentration of NaOH in the mixture, was studied. The results showed that new method is simpler, more rapid, more completely and accurate, the overwhelming reason being that it had no effect on stability of sodium polysulfide.
