摘要
以化工厂硫酸法生产的钛白粉副产品七水硫酸亚铁为原料，用双氧水作氧化剂，在聚合硫酸铁的基础上合成了聚合磷硫酸铁，由于在其结构里引入了磷酸根，使其性能与聚合硫酸铁的性能有根本的不同。
The polyferric phophate-sulphate has been synthesized on the basis of polyferric sulphate. In the course of the synthesis, the ferrous sulphate hentohydrate which is the byproduct of titanium dioxide produced by sulphate method in the chemical engineering factory is taken as the material, and the hydrogen hyperoxide is taken as the oxidizer. The properites of the polyferric phosphate-sulphate differ from those of the polyferric sulphate radically due to the structure of the polyferric containing the phosphate ions.
