Abstract:
The catalytic oxidation of aniline was evaluated to provide the foundation for risk-based treatment of aniline-contaminated solid-waste using Fenton reagent (catalyzed hydrogen peroxide). The operating conditions of Fenton reaction were investigated and the factors of the chemical treatment were analyzed. The optimal conditions were following: 1.1 mL H2O2 per gram of dried solid waste, V (H2O2) 0.5-1.0 mL x min(-1), addition of Fenton reagent twice or three times at pH = 3.0 in 50 grams of waste, and the aniline removal rate is over 99.86% for 30 min reaction after reagent addition. Furthermore, mechanisms of affecting factors in solid-waste were analyzed; the key and controlling steps of reactions were expounded in the system, which provided safeguard for further treatment ranging from stabilization and solidification to landfill.
