Insights into reactive oxygen species formation induced by water-soluble organic compounds and transition metals using spectroscopic method

Ambient particulate matter (PM) can cause adverse health effects via their ability to produce Reactive Oxygen Species (ROS). Water-Soluble Organic Compounds (WSOCs), a complex mixture of organic compounds which usually coexist with Transition Metals (TMs) in PM, have been found to contribute to ROS formation. However, the interaction between WSOCs and TMs and its effect on ROS generation are still unknown. In this study, we examined the ROS concentrations of V, Zn, Suwannee River Fulvic Acid (SRFA), Suwannee River Humic Acid (SRHA) and the mixtures of V/Zn and SRFA/SRHA by using a cell-free 2′,7′-Dichlorodihydrofluorescein (DCFH) assay. The results showed that V or Zn synergistically promoted ROS generated by SRFA, but had an antagonistic effect on ROS generated by SRHA. Fluorescence quenching experiments indicated that V and Zn were more prone to form stable complexes with aromatic humic acid-like component (C1) and fulvic acid-like component (C3) in SRFA and SRHA. Results suggested that the underlying mechanism involving the fulvic acid-like component in SRFA more tending to complex with TMs to facilitate ROS generation through π electron transfer. Our work showed that the complexing ability and complexing stability of atmospheric PM organics with metals could significantly affect ROS generation. It is recommended that the research deploying multiple analytical methods to quantify the impact of PM components on public health and environment is needed in the future.     

活性艳红X-3B微波辅助光催化脱色的研究

研究了微波辅助光催化氧化(MW/UV/TiO2)处理活性艳红(X 3B)模拟废水。结果表明:400mg/LX 3B在反应150min时的脱色率由UV/TiO2体系的7.07%、MW体系的13.52%提高到了MW/UV/TiO2体系的56.35%。脱色反应速率随初始浓度(CX 3B)的增大而减慢;在强酸性介质中,脱色率更高;光照度(E)越强,越有利于X 3B脱色反应;改变催化剂投加量对X 3B脱色影响不大;H2O2浓度增加,X 3B脱色率升高;在以上条件下,X 3B的脱色反应均符合一级反应动力学方程,脱色反应中同时存在自由基反应与直接光解反应。
