磷酸在饲料、食品和现代新型凝胶材料等行业中具有非常重要的作用，随着磷酸及磷酸盐行业的高速发展，国内外对磷酸及磷酸盐的需求不断增加。目前生产磷酸主要用的是湿法工艺，净化后的湿法磷酸可以用于各种工业生产需求。根据湿法磷酸净化技术的不同，综述了近年国内外净化湿法磷酸的工艺研究及结果。
Phosphate plays a very important role in the modern industries,such as forage,food and modern new gel materials,etc.With the rapid development of the phosphate and phosphate industries,the demand of phos-phate and phosphorous salts is increasing constantly at home and abroad.At present,the main method of producing phosphate is the wet-process,after which the purified phosphate can satisfy the need of various industrial productions. Based on the difference of the wet-process technology of the phosphate,the technical research and results of the wet-purified phosphate of recent years at home and abroad are summarized.
