花生壳活性炭对铜离子的吸附研究

In this paper, the main component part and multiple use of peanut shell were listed . Moreover, the optimal condition of activated carbon from peanut shell by using the zine chloride activation method was studied in the paper. The optimum conditions are as follows: the weight ratio of peanut shell to ZnCl2 solution1∶2, mass percentage of ZnCl2 50%, activated temperature 600℃, activated time 1 hour. In addition, the effect of pH on activated carbon of peanut shell adsorbed Cu2+ was studied, and an orthogonal test was designed to optimize the preparation. The optimum conditions as follows: adsorption temperature 45℃, adsorption time 60 min, oscillation frequency 200 r/min and adsorbing material 2g/L. Some experiments were projected for contrast study with the adsorption function of marketed activated carbon.
