摘要
以废旧橡胶颗粒、膨润土与高岭土为吸附剂,研究其对水溶液中苯酚的吸附性能,得到吸附等温线,确定苯酚浓度对吸附量的影响。结果表明:三种吸附剂对苯酚的吸附性的强弱为橡胶颗粒>膨润土>高岭土。在苯酚浓度较低时,橡胶颗粒和两种黏土对苯酚均具有较好的去除率,且橡胶颗粒的吸附效果明显好于黏土;随着苯酚质量浓度的增大,去除率降低。橡胶颗粒、膨润土和高岭土对苯酚的吸附符合Freundlich和Langmuir吸附等温式。
With waste tire rubber particles, bentonite and kaolin as adsorbent, the adsorption oi pnenoi in a queous solution was studied. The adsorption isotherms were determined and the influence of concentration of phenol on adsorption was analyzed. The results show that the rubber particles can adsorb more phenol than bentonite and kaolin. Under lower phenol concentration, the rubber particles have better removal ability than bentonite and kaolin. With the increase of phenol concentration, The adsorption isotherm of rubber particles, bentonite and kaolin agree wtih the removal rate decreases. Freundlieh model and Langmuir model.
