【摘要】 以BaP污染物为研究对象,采用Fe²⁺/PS工艺氧化降解Ba P,系统考察各因素对Fe²⁺/PS工艺去除Ba P的影响,同时基于gaussian软件探究Ba P降解机理,提出降解路径并进行毒性测试。结果表明:实验降解的最佳反应条件为Fe²⁺浓度为450 mg/L,过硫酸钠浓度为1000 mg/L,且酸性条件及温度升高更利于苯并芘的降解;理论计算揭示了Fe²⁺/PS工艺降解Ba P的机理,且过程中未发现有毒有害的物质,存在潜在风险的可能性较低。更多还原

【Abstract】 This study takes bap pollutants as the research object,uses the Fe²⁺/PS process oxidation degradation Ba P,investigates each factor to the Fe²⁺/PS process removal Ba P influence,simultaneously based on the gaussian software to explore the degradation mechanism,proposes the degradation path and carries on the toxicity test. The results show that the optimum reaction conditions for experimental degradation are Fe²⁺concentration of 450 mg/l,sodium persulfate of 1000,and the condition and temperature increase are more favorable for the degradation of benzopyrene. The theoretical calculation reveals the mechanism of degradation Ba P in Fe²⁺/PS process,and there is no toxic and harmful substances in the process,and potential risk is low.更多还原
