【Abstract】 New technology for production of KH\-2PO\-4 from NH\-4HCO\-3, KCl and H\-3PO\-4 was developed. Compared with other technology, its process is simple and doesn’t discharge three wastes. The raw materials are easily acquired, the cost is also low. The recovery rate of KH\-2PO\-4 can reach 95%, and the quality of the production can accord with the State Standard.更多还原
