摘要
介绍了一种新的聚合硫酸铝合成新工艺，以硫酸铝、碳酸氢钠等物质为原料，反应温度７０℃；反应时间２ｈ，合成出聚合硫酸铝（ＰＡＳ），其ｐＨ值为４．１，碱化度为５８％，铝含量（以Ａｌ２Ｏ３计）为１６．０％，同时对其性能进行了对比研究．
Introduces a new synthetic technology of poly aluminum sulfate by using aluminum sulfate.and sodium bicarbonate as main meterial,Under the condition of 70℃ of reaction temperature and 2h of reaction time.The pH of synthesized PAS is 4.1,basicity is 58% and Al 2O 3 is 16.0%.Some experiments for its coagulation performance were conducted.
