摘　　要：以化学法合成的新生态MnO2作吸附剂,对水中苯酚进行吸附研究,探讨影响吸附的因素和吸附机理。结果表明,新生态MnO2对苯酚的吸附率很高,作用速度快,20min内就能达到吸附平衡。其中吸附前溶液的pH值是影响吸附的主要因素。新生态MnO2对苯酚的吸附作用主要是由于其表面的两性结构决定的。In this research, the adsorption of phenol with the nascent MnO2 was studied. Influencing factors was investigated in the detail. The experimental results showed that nascent MnO2 for phenol has high adsorption rate and fast rave. In about 20 mins, it reached the equilibrium state. The pH values of solution before adsorption were the key factor. The adsorption of phenol with the nascent MnO2 was decided by the amphiphilic facial structure.
