摘　　要：近年来我国湿法磷酸溶剂萃取净化逐步形成规模化生产,其生产过程中副产的萃余酸的合理利用已成为企业急待解决的技术难题。本文综述了湿法磷酸溶剂萃取净化副产萃余酸的利用现状及优缺点,介绍了几种典型萃余酸利用的方法,并就萃余酸合理利用进行了展望。Recent years, purification of wet-process p aosphoric acid by solvent extraction has gradually formed largecale pro- duction in China, during the production, rational utilizat on of ex- traction residual acid by-product has become the technical prob- lems that enterprises press for solution. This paper summarized the utilization status, advantages and disadvantages of extraction residual acid by-product of solvent extraction purification of wet- process phosphoric acid, introduced several typical production methods of utilizing extraction residual acid and envisioned the ra- tional utilization of extraction residual acid.
