The Direct Analysis of Diquat and Paraquat in Lake Water Samples by per Aqueous Liquid Chromatography

Methods of analysis for paraquat and diquat are of interest to the food, environmental, and clinical analysis fields due to their widespread use, availability, and toxicity. In this study, we developed a method for the direct analysis of these compounds in water and applied the method to an environmental study where diquat was applied to control aquatic weeds in a local lake. The method provides a simple, direct, sensitive, and fast method of analyzing these compounds.
