It is mainly used as a discharging agent, color-discharging agent, reductant in printing a dyeing industry. As an activating agent for production styrene-butadise rubber and synthetic resin. Also be used to decolourize and bleach some organic matters, for example: as a bleaching agent in synthetic rubber, sugar-making, and food industry. It may be substituted for the Sodium Hydrosulfite in some special conditions.
