摘要
对萃取HCl法、萃取HNO3法、HCl和HNO3分别萃取法3种溶剂萃取法在制取硝酸钾的工艺流程、优点和应用情况进行了介绍,指出溶剂萃取法制取硝酸钾目前需要解决的问题,并对该技术国产化进行了展望。
The flow, advantages and its application in potassium nitrate preparation with three solvent extraction processes including HCl extraction, HNO3 extraction and HCl＆HNO3 extraction separately, are introduced. The current problems existing in these processes to be solved are pointed out, with their localized manufacturing prospected.
