5. Use of Trisodium citrate dihydrate
Trisodium citrate dihydrate has a sour taste similar to citric acid, and is salty as well. It is often used as a food preservative, and as a flavoring in the food industry. In the pharmaceutical industry it is used to control pH. And trisodium citrate dihydrate may be used as an alkalizing agent, buffering agent, emulsifier, or sequestering agent. What’s more, it is 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.
