摘要
对海泡石除铅离子的条件及机理进行了实验探讨。结果表明 ,海泡石对去除水中的铅离子具有较好的作用。可以将含Pb2 + 10mg/L的水净化至 0 .0 5mg/L以下 ,去除率达到了 99%以上 ,海泡石与含Pb2 + 溶液的作用时间、海泡石用量、水中Pb2 + 浓度以及酸度等因素都会影响Pb2 +
The conditions and mechanism of treating Pb 2+ from waste water by meerschaum have been investigated in this paper.Some major factors that effecting the treating process such as treating time and pH,concentration of Pb 2+ ,amount of meerschaum are studied.The experimental results show that meerschaum has great effect on treating Pb 2+ from waste water.It may change concentration of Pb 2+ from 10mg/L to below 0.1mg/L.The removing rate of lead is above 99%.The mechanism of removing lead is based on the cooperation of absorption with ion exchange.
