摘要
在静态条件下,从p H、温度、浓度等方面考察了改性红辉沸石对Cd2+离子交换能力的影响以及Cd2+离子与其他重金属阳离子共存的影响,同时也考察了改性沸石对模拟废水的重金属去除效果。结果表明,改性红辉沸石对Cd2+的去除率达到99%以上,且同时也能使Pb2+,Zn2+,Cu2+离子达到国家标准排放。
Under the static condition ,the influences of the modified zeolite on the exchange capacity Cd2＋ ion are investi-gated in aspects of pH ,temperature ,concentrations and so on ,as well as the effects of Cd2＋ ions coexisted with other heavy metal cations and simultaneously the removal effects of the modified zeolite on the heavy metals in the simulated wastewater . The results show that the removal rate of the modified zeolite to Cd2＋ ions can achieve more than 99% and also can make other metal cations ,such as Pb2＋ ,Zn2＋and Cu2＋ ,meet the national emission standards .
