Reaction Mechanism of Photoreduction of 2,4-Dichlorophenoxyacetic Acid in Surfactant Micelles
The direct photolysis of 2,4-dichlorophenoxyacetic acid (2,4-D) in water is slow and ineffective, but surfactant micelles can greatly enhance the photochemical reaction of organic contaminants. The… Expand
Pyrazine derivatives affect membrane fluidity of vascular smooth muscle microsomes in relation to their biological activity.
We have previously demonstrated that several structurally similar pyrazine derivatives, tetramethylpyrazine (TMP), triethylpyrazine (3EP) and tetraethylpyrazine (TEP) consistently inhibited a wide… Expand

The objective of this project is to explore the iron-catalyzed oxidation performance of 2-chloroaniline (2-ClA) under different illumination wavelengths. UV irradiations with different wavelengths at… Expand
Amphoteric Effect of Humic Acids in Surfactant-Aided Photolysis of Polychlorobiphenyls
Polychlorobiphenyls (PCBs) are one of the most environmentally problematic organic contaminants present in soils and sediments due to their long-life in direct disposal or spills in soil. It is known… Expand

Effect of ferrioxalate-exchanged resin on the removal of 2,4-D by a photocatalytic process
Abstract A new approach combining sorption and an advanced oxidation process has been developed for wastewater treatment. Fe 3+ is incorporated into a cationic resin with or without the oxalate to… Expand
The role of oxalate in the kinetics of 2,4-D oxidation over ferrous ion-supported catalysts
Abstract The cation-exchange resin loaded with ferrous ion (CERF) catalyzes the photochemical oxidation of 2,4-D. The co-existence of UV light and oxalate is the key to initiating the attack by… Expand
