</p>
<p>
<span style="font-size:16px;"><strong>Sodium hydrosulfide</strong> is one of the inorganic chemicals.It is used in the dyestuff industry for the synthesis of organic intermediates and auxiliaries for the preparation of sulfur dyes. The tanning industry is used for the depilation and tanning of hides and skins. The fertilizer industry is used for the de-activation of monomeric sulfur in activated carbon desulfurizers. The mining industry A large number for the beneficiation of copper, man-made fiber for the sulfite dyeing, is the manufacture of ammonium sulfide and pesticide ethanethiol semi-finished raw materials, but also for waste water treatment.</span>
