Utilizing Fly Ash to Prepare Polysilicon Acid and Compounded PFS and the Study of Its Properties
粉煤灰制备聚硅酸复合聚合硫酸铁及性能研究

Fly ash which is a kind of solid waste of power station in Dalian was prepared as polysilicon acid,and compound polymerized ferric sulphate and its properties was studied.Fly ash was dipped in NaOH solution.The effects of temperature,concentration of NaOH solution and reactive time were examined respectively on the conversion efficiencies of silicon.Then the solution which was rich in silicon was used to compound polymerized ferric sulfate(PFS)and got compounded polymerized ferric sulphate(F-PFS),and evalua...
