摘要
研究常温常压、pH值接近中性的条件下,δ-MnO2对苯酚的去除作用。通过气相色谱分析δ-MnO2处理前后苯酚溶液的变化,得到在该条件下,δ-MnO2对苯酚的氧化作用可以忽略;通过通入空气和氮气进行比较,得到在该条件下,空气作为氧化剂时,δ-MnO2没有催化氧化作用;δ-MnO2对苯酚的去除主要是吸附作用。
This paper mainly discusses removal of phenol by δ-MnO 2 at neutral pH,normal temperature and pressure.According to the composition of the phenol solution with and without treatment by δ-MnO 2,oxidation of δ-MnO 2 can be neglected.When the air as the oxidant,the phenol removal is mainly adsorption,rather than the catalytic oxidation,which is according to the composition of access for air and nitrogen.
