Cataphotolysis of Propanil in water using nanotechnology

Yu Z., Wu V., Li Z., California State Polytechnic University, Pomona, US

Irrigation of farmland consumed approximately 80% of total water usage in California. The costs associated with groundwater monitoring and cleansing have cost the state more than $33 millions of dollars. This research project has significant [...]

Removal of Water Contaminants Using Nanotechnology

Yu Z., Li Z., California State Polytechnic University, Pomona, US

Propanil, Diuron, Simazine, and Metolachlor are widely used as herbicides and pesticides in California agriculture and across the U.S., and are considered to pose a significant threat to water contamination by transporting chemicals into surface [...]

Photocatalysis of Rhodamine B in water using nanotechnology

Yu Z., Li Z., California State Polytechnic University, Pomona, US

There are several techniques currently used for water organic contaminants removal, including Activated Carbon Adsorption, Chlorination, UV Photolysis, Ozonation, and Ferrate Oxidation. Although these techniques are useful in treating contaminated water, they have limitations in [...]
