摘要
Abstract
The oxidation of phenol by potassium persulfate activated with heat and transition metal ion (Fe2+) was investigated. The degradation efficiencies of phenol and COD were 50% and 45% when the ratio of potassium persulfate to phenol was 0. 50 heating at 100 ℃ for 3 h. When temperature was at below 30℃ phenol cannot be degraded. Compared with potassium persulfate activated by heat alone, the addition of Fe2+ can enhance the degradation
efficiencies of phenol and COD which was increased by 11% and 8% at 100℃ , respectively. In the whole reaction system, pH had a great impact on the degradation efficiencies of phenol. It was demonstrated that potassium persulfate produce more sulfate free radicals in acid conditions, so as to achieve the better removal efficiency. 关键词
