推荐:针对新兴污染物去除效率低、传统Fenton技术需酸性环境等问题,研究人员通过低浓度Fe2+&H2O2(1:1摩尔比)体系在中性条件下高效降解双酚A(BPA),揭示其通过原位羧基化自供酸机制实现90%以上降解率,并阐明中间体毒性随浓度升高的演化规律,为低成本 ...
这篇综述系统阐述了(AOPs)在降解偶氮染料中的应用价值,重点解析了芬顿(Fe2+/H2O2)、类芬顿(Fe2+/S2O82?)及光辅助工艺的 ...
1. 高级氧化技术的定义:利用强氧化性的自由基来降解有机污染物的技术,泛指反应过程有大量羟基自由基参与的化学氧化技术。其基础在于运用催化剂、辐射,有时还与氧化剂结合,在反应中产生活性极强的自由基(一般为羟基自由基,· OH),再通过自由基与 ...
In a fundamental process throughout nature, reduced iron unleashes the oxidative power of hydrogen peroxide into reactive intermediates. However, notwithstanding much work, the mechanism by which Fe2+ ...
ROS-driven methane formation in cells. Reactive oxygen species (ROS) such as hydrogen peroxide (H2O2) are generated during cellular metabolism and their production is enhanced by oxidative stress.
