Rapid Disposal of Pentachlorophenol Contaminated Soils in a Soil Reactor

Abstract

At present the point source soil contaminations by toxic chemicals are very serious, and many methods are used for the rapid disposal. In recent years, Fenton’s reagent has been paid more and more attention because of its high oxidative potential and simplicity. In this work, pentachlorophenol (PCP) was used to simulate contaminated soils, and a tilted soil reactor was designed to study its decomposition by Fenton’s reagent. The effects of six variables on PCP degradation were evaluated: (1) initial soil-water ratio; (2) reaction time; (3) H2O2-Fe2+ molar ratio; (4) dosing method; (5) reaction tank rotating speed and (6) initial H2O2 concentration, and the optimum operating conditions were identified. However, further research is required for practical application.
