【摘要】：為深入探索酶催化技術(shù)在海洋石油污染處理中的應(yīng)用,以游離辣根過氧化物酶(HRP)催化降解海水中柴油污染,研究了酶用量、溶液p H值、柴油初始濃度和催化反應(yīng)時間等因素對酶催化降解海水中柴油污染的影響,確定了HRP催化降解海水中柴油污染的優(yōu)化工藝條件,同時考察了反應(yīng)助劑對海水中柴油污染去除率的影響。結(jié)果表明:HRP能有效催化降解海水的柴油污染,當(dāng)海水中柴油的質(zhì)量濃度為1.2g/L時,在溫度為25℃、HRP加入量為1.6 U/m L、H_2O_2為250 mg/L、溶液pH為5的條件下,催化降解3 h,柴油去除率可達(dá)90.77%;聚乙二醇(PEG)對HRP催化降解海水中的柴油污染有較顯著的影響。
[Abstract]:In order to explore the application of enzyme catalysis technology in the treatment of marine oil pollution, the free horseradish peroxidase (HRP) was used to catalyze the degradation of diesel oil pollution in seawater. The amount of enzyme and pH value of solution were studied. The effects of initial concentration of diesel oil and catalytic reaction time on the degradation of diesel oil pollution in seawater catalyzed by enzyme were studied. The optimum conditions of HRP catalytic degradation of diesel oil pollution in seawater were determined. At the same time, the effect of reaction auxiliaries on the removal rate of diesel oil pollution in seawater was investigated. The results show that HRP can effectively catalyze the degradation of diesel pollution in seawater. When the mass concentration of diesel oil in seawater is 1.2g/L, when the temperature is 25 鈩，
