“s-Triazine herbicides and their metabolites are found in many surface and groundwaters mainly in the Midwest but also throughout the country. Although concentrations are higher during the summer months, the compounds can be found in the waters most of the year. The s-triazines include atrazine, cyanazine, simazine, and propazine. Atrazine, unlike the other s-triazines, has been proven to be easily removed from water using activated carbon.
The purpose of this study was to examine the treatability of selected s-triazines and their metabolites with activated carbon. In this study, several batch isotherms were conducted using two parent compounds, eight metabolites, two different pH levels, two different temperatures, two different source waters, and four commercial activated carbons.
All compounds were proven to be effectively removed using activated carbon at all condition combinations. Although pH and temperature had a minor effect, slightly higher carbon capacities were realized at a higher pH and at a lower temperature. Calgon WPH Powdered Activated Carbon was found to be the most effective carbon for removing the s-triazines”--Abstract, page iii.
