本研究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对苯酚的吸附率大,其中吸附前溶液的pH值是影响吸附的主要因素。用50mg的新生态MnO2,调节吸附前pH值为2.0,处理100mg/L的苯酚模拟废水去除率可达80%。
The adsorption of phenol with the fresh MnO2 was studied. Influencing factors were investigated in detail. The experimental results showed that the adsorption of phenol on the fresh MnO2 has high adsorption rate, and pH values of solution before adsorption was the key factor on the adsorption. The efficiency of removal was up to 80% in the experiment.
