This standard specifies the determination method of sodium sulfide content in sulfide dyes. The potential Titrimetric method is used to calculate the content of sodium sulfide by measuring the ferrous sulfide settling generated by the reaction of sulfide dyes with ferrous sulfate. This method is suitable for accurately assessing the content of sodium sulfide in sulfide dyes and provides a basis for dyestuff quality control.
