摘要
以钠基膨润土为原料,制备了铝钛交联改性膨润土,并应用于实验室废水的处理,考察了pH值,改性膨润土的用量和搅拌时间对废水的COD、浊度和色度去除率的影响。当pH=4,投加量为6g/L,搅拌时间为30 min时,COD最高去除率为50.90%;当pH=5,投加量为6 g/L,搅拌时间为30 min时,浊度的最高去除率为92.10%;当pH=3,投加量为6 g/L,搅拌时间为30 min时,色度的最高去除率为94.00%。
Al - Ti Cross - Linked Modified Montmorillonites was synthesized from Na- montmorillonite and has been applied in treating laboratory wastewatcr. Some factors such as pH, throwing amounts of modified montmorillonites and time were examined, which affect the removal rate of COD,turbidity and chroma. The results showed as follows： at optimized conditions their removal rate has reached 50.90 % ,92.10 % and 94.00 %, respectively
