Introduction

"Mixed Valence Copper(cu)/silica Nanocomposite

Copper (Cu) compounds are widely used as effective agricultural bactericides. Continuous use of these materials has led to Cu accumulation in soil over time. The United States Environmental Protection Agency (US EPA) is concerned about potential Cu contamination in the environment. Improving biocidal efficacy of Cu is an attractive alternative allowing reduction of Cu amount per application.
