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

摘要

Diquat and paraquat are used throughout the world as effective herbicides. These compounds are the active ingredients in a range of formulations aimed at terrestrial weeds and crops, as well as aquatic weeds. The ever-increasing need to control invasive aquatic weeds in the United States will increase the demand for the use of herbicides such as diquat, which can quickly and effectively control weeds in water. The popularity of these herbi-cides is attributed to the efficacy, speed, and localization with which they act: These herbicides are effective within days of application, act only upon the parts of the plant they are in contact with, and deactivate upon contact with soil.
