Sodium Sulfide Low Iron (5PPM)


Sodium sulfide, also known as alkali sulfide, smelly alkali, is an inorganic salt, strong moisture absorption, soluble in water, hydrolysis to generate sodium hydroxide and sodium hydrosulfide, aqueous solution is strongly alkaline, has a strong corrosive, so in the dye industry for the manufacture of sulfur dyes, green sulfide, blue sulfide or dye intermediates reducing agent, mordant;

Sodium Sulfide Low Iron (10PPM)


Sodium sulfide, also known as alkali sulfide and smelly alkali, is an inorganic salt with strong moisture absorption and easy solubility in water. Hydrolysis generates sodium hydroxide and sodium hydrosulfide. The aqueous solution is strongly alkaline and corrosive. Therefore, it is used in the dye industry to make sulfur dyes, sulfide green, sulfide blue or dye intermediate reducing agent and mordant. Used as flotation agent for ore in colored gold industry. Used as depilatory agent for hide in tanning industry;
