摘要
以蛭石和人造沸石为吸附剂,采用正交实验的方法研究吸附时间、样品用量、溶液pH值、溶液的初始浓度对其吸附Pb^(2+)和Cd^(2+)的影响及在模拟废水中对Pb^(2+)的吸附性能.蛭石对模拟废水中Pb^(2+)的吸附率为86.27%,对Cd^(2+)的吸附率为85.25%.人造沸石对Pb^(2+)吸附率为99.78%,对Cd^(2+)的吸附率为99.98%,人造沸石对Pb^(2+)和Cd^(2+)两种重金属离子的吸附性能比蛭石好.
In the article, it was discussed that the study on the adsorption performance and influence factors, such as the adsorption time, the sample dosage, the pH, and the concentration of solution, with vermiculite and artificial zeolite as adsorbent to absorb Pb^2＋, Cd^2＋ and Pb^2＋ in the mixture with the concentration of Cd^2＋ changed by orthogonal experiment. Uhimately, it draws the following conclusions： the maximal adsorption rate of Pb^2＋ and Cd^2＋ by the vermiculite was 86.27% and 85.25%, and the maximal adsorption rate of Pb^2＋ and Cd^2＋ by the Artificial Zeolite was 99.78% and 99.98%. The result of experiment indicates that the adsorption rate of artificial zeolite was higher than vermiculite to adsorb Pb^2＋ and Cd^2＋.
