摘要
研究了用煅烧活化后的工业废弃物硅酸钙经吸附水溶液中的磷,探讨了煅烧温度、活化硅酸钙投加量、溶液pH及吸附时间对活化硅酸钙吸附除磷的影响。结果表明:在煅烧温度800℃、活化硅酸钙投加量6g/L、溶液pH为8.0、吸附时间3h条件下,溶液中磷的吸附去除率为99.48%;吸附过程符合Freundlich吸附等温式。
The removal of phosphate from aqueous solutions using activated calcium silicate was investigated .T he influence of calcine temperature ,activated calcium silicate dosage ,pH of aqueous solutions and adsorptive time on treatment efficiency were discussed .The results show that the removal rate of P（Ⅴ） can reach 99 .48% when adsorption was balance under pH of aqueous solution is 8 ,dosage of activated calcium silicate is 6 g/L ,absorptive time is 3 hours .T he fitting results show that the adsorption process could be described by Freundlich isotherm .
