研究了酸性条件下TS-1分子筛催化O3/H2O2体系（O3/H2O2/TS-1）对降解水中乙酸效率的影响，优化了相关工艺参数，并对其作用机理进行了分析。结果表明，在pH为2.8时，TS-1的加入能显著提高臭氧化的降解效率。优化工艺参数表明，当过氧化氢投加量为3 g/L，TS-1投加量为5 g/L时，O3/H2O2/TS-1体系对乙酸具有较高的降解率，60 min后O3/H2O2/TS-1体系对乙酸...
利用活性炭纤维作为阴极，比较了活性炭纤维电极和石墨板电极产H2O2的浓度，并对影响活性炭纤维电极产H2O2的因素(pH、电流密度和电解质浓度)进行了研究.研究发现，活性炭纤维电极电还原产生H2O2的浓度远大于石墨板电极.当实验在pH=3.00、电流密度8.89 mA/cm2和电解质(Na2SO4)浓度0.05 mol/L的条件下，240 min的电解时间内电还原产生H2O2的浓度最高可达556.1...
制备了负载在Na-Y分子筛上的Fe-Cu-Mn-Y复合催化剂, 并对其在非均相UV/Fe-Cu-Mn-Y/H2O2体系中催化氧化4BS染料废水进行了研究。 结果表明, 非均相UV/Fe-Cu-Mn-Y-H2O2体系对4BS染料废水的处理具有很高的效率。 在基准条件下, 反应时间为20min时, 废水中4BS的去除率达到了93.7%。 与均相UV/Fenton体系不同, 非均相UV/Fe-Cu-Mn...
