  • 摘要: 研究了辉光放电等离子体降解水中典型的环境内分泌干扰物邻苯二甲酸二丁酯（DBP）及降解过程中过氧化氢（H2O2）的生成规律。考察了电解质种类、共存污染物（甲醇、叔丁醇）及催化剂等条件对DBP降解及H2O2生成的影响。结果表明，在硫酸钠溶液中DBP降解效率和H2O2生成速率最高；甲醇、叔丁醇等共存污染物对DBP降解和H2O2生成有抑制作用；Fe2+，Fe3+和Cu2+对DBP的降解有催化作用，其催化效果为Fe2+>Fe3+>Cu2+。用高效液相色谱、离子色谱及气质联用仪等仪器分析了降解中间产物，提出了可能的降解机理。
    Abstract: Degradation of dibutyl phthalate (DBP, a typical kind of endocrine disrupting chemicals), and formation of hydrogen peroxide (H2O2) induced by glow discharge plasma in aqueous solution were investigated. Effects of supporting electrolytes, coexisting pollutants, and catalysts on the degradation of DBP and the formation of H2O2 were studied. Experimental results showed that removal of DBP and the formation of H2O2 were higher in sodium sulfate solution than those in sodium chloride. Both the DBP removal and the H2O2 formation rates decreased in the presence of coexisting pollutants, indicating that hydroxyl radicals were the most probable oxidants responsible for DBP degradation and the precursors of H2O2. Results show that the Fe2+, Fe3+ and Cu2+ have enhancing effects on DBP removal, with the sequence of Fe2+>Fe3+>Cu2+. Major intermediate products were identified by HPLC,IC, GC-MS,and the possible degradation mechanism was discussed.
