摘要
开发出一种用废盐酸和劣质高岭土生产聚合氯化铝的方法。分别考察了焙烧温度、焙烧时间、盐酸用量以及酸浸时间对铝浸出率的影响。试验结果表明 :依照该工艺生产的聚合氯化铝 ,其各项指标符合GB 15 892—
A process for preparing polyaluminum chloride from waste chlorhydric acid and poor quality kaolin has been developed.The influence of calcinations temperature and time,chlorhydric acid dosage,acid leaching time on leaching rate of aluminum was explored in the tests.The results show that polyaluminum chloride prepared by the process can meet the standards GB15892-95.
