摘　　要：研究了以新生MnO2为吸附剂,对水中苯酚的脱除作用,并探讨了影响吸附的因素,结果表明:新生MnO2对苯酚的吸附率高,吸附前溶液pH是影响吸附效果的主要因素。在实验条件下可使苯酚的脱除率达到84.8%～90%。The adsorption of phenol with fresh MnO2 and its influencing factors were studied. The results showed that the adsorption rate of phenol on the fresh MnO2 was high and pH values of solution before adsorption were the key factor on adsorption. The ed removal efficiency was up 84.8%～90% in the experiment.
