Application:
Used as anticoagulin,chemical reagent,food additive,developer,buffer emulsifying agent, stabilizing agent and used in nonhydrogen electroplation as well as widely in tail gas absorption process of sulfur dioxide for chemical and metallurgy industries. Its absorptivity reaches 99%. The waste absorbed may be regenerated into sulfur dioxide liquid and potassium citrate for cyclic utilization. The daily-use chemical detergent with potassium citrate. As raw material instead of sodium phosphate trimer, it is non-toxic and non-pollution.It also may be used as buffer agent in cosmetic production.
