摘　　要：综述了湿法磷酸净化的常用方法及优缺点,介绍了典型的溶剂萃取法工业流程以及国内外的研究现状,详细介绍了由四川大学和贵州宏福实业开发有限总公司共同开发的新型湿法磷酸净化技术,该技术流程短,成本和能耗低,有广阔的应用前景。The advantages and disadvantages of different methods for wet process phosphoric acid (WPA) purification are discussed. The typical commercial process of solvent extraction and research progress in China and foreign countries are reviewed. A new technology for WPA purification developed by Sichuan University and Guizhou Hongfu Co., Ltd is introduced. It has the (characteristics) of short process, low cost and energy consumption, and so has wide application prospect.
