摘要
以硅酸钠、硫酸铁、硫酸铝和硼砂为原料制备无机高分子含硼聚硅酸硫酸铝铁絮凝剂(PFASSB),最佳制备条件为:n(Fe):n(Al):n(Si)=0.5:015:1.0,n(B):n(Si)=0.15:1,活化pH值为2.0,活化时间为1h,PFASSB具有优良的稳定性和絮凝性能,最佳稳定时间是60d。
The inorganic polymer flocculation PFASSB( Polymeric Ferric & Aluminum Silicate-Sulfate Containing Boron) is prepared using sodium silicate, ferric sulfate, aluminum sulfate and borax as raw-materials. The optimal preparation conditions are as follows:n(Fe):n(Al):n(Si)=0.5:0.5:1,0; n(B):n(Si)=0.15:1; activation pH value is 2.0 and activation time is 1 h. PFASSB has a banded structure featuring excellent stability and flocculation, The best stability time is 60d.
