  • 摘要: 药品和个人护理用品(PPCPs)是一类新兴有机污染物,对环境存在潜在的威胁,已引起国内外的广泛关注。以典型PPCPs物质-布洛芬(2-(4-异丁基苯基)丙酸)作为研究对象,采用铁炭微电解法对其进行降解处理,考察了影响布洛芬去除效率的主要因素,确定了各影响因素的最佳操作条件为:离子浓度0.8 g/L,反应时间120 min,铁屑用量1.5 g/L,铁炭质量比2:1,pH为4.0;在此条件下,布洛芬去除率可达80%以上,布洛芬降解过程符合一级反应动力学。
    Abstract: Pharmaceutical and personal care products (PPCPs) are an emerging class of organic contaminants that have raised concerns widely because of their potential menace to the environment. Typical PPCPs-ibuprofen (2-(4-isobutylphenyl) propanoic acid) was selected as the goal substance, and treated by iron-carbon micro-electrolysis in this study. The main factors that have effects on removal efficiency of ibuprofen were investigated, and the optimal operation conditions were as following: 0.8 g/L of ionic concentration, 120 min of the reaction time, 1.5 g/L of iron dosage, 2 of the mass ratio of Fe/C, 4.0 of pH. Under such conditions, the removal efficiency of ibuprofen is up to 80%, and the degradation of ibuprofen basically accords with the first order kinetics.
