摘要
以天然煤矸石为原料 ,通过酸溶一步法将煤矸石中的氧化铝溶解取出来 ,并通过条件试验 ,确定溶出量最高时的工艺条件。再经过盐基度的调整 ( 70 %左右 ) ,形成碱式聚合氯化物 ,该聚合物具有很好的絮凝作用 。
The natural gangue was used as material,dissolved Al 2O 3 that contained in it through acid dissolve after only one step,and determined the best reaction condition by cross experiment.And then adjusted the basic degree of salinity(about 70%),the alumina formed alkaline poly chlorate.This product became a best water clarifier.
