| 摘 要： | 煤矸石是采煤过程之废料。本文利用煤矸石制备出了聚合氯化铝铁（ＰＡＦＣ）：一种新型无机高分子絮凝剂，探讨了Ｆｅ＾３＋的稳定性与溶液离子强度之间的关系，发现溶液的离子强度越大，则产生Ｆｅ（ＯＨ）３沉淀时的ＰＨ越高。研究了ＰＡＦＣ水解产物的ζ电位及絮凝效果随ＰＨ的变化情况，比较了ＰＡＦＣ、ＰＡＣ和ＰＦＳ的除浊性能，ＰＡＦＣ在ＰＨ为７．０－８．２范围内除浊效果最佳，ＰＡＦＣ的除浊效果优于ＰＡＣ。

| Abstract: | Polyaluminium ferric chloride (PAPC) , a new type of irtorganic flocculant, is prepared by using gangue, a kind of waste from coal-mine, and hydrochloric acid as raw materials. The relation between the stability of ferric ion and the ionic strength of solution is investigated. It is found that the higher the ionic strength, the higher the pH value when precipitate Fe(OH)3 is formed. The ?potential of hydrolyzate and flocculating effect of PAFC under different pH value are discussed. PAFC gives the best turbidity removal effect in the range of pH7. 0 - 8. 2. Compared with PAC, PAFC gives better turbidity removal effect. |
