The objective of this research was to perform an analysis on a granular activated carbon (GAC) and a powdered activated carbon (PAC) system for removing a mixture of herbicides and metabolites from water. To meet this objective, the research was divided into three parts: to perform single solute isotherms on the herbicides and metabolites; to perform multi-solute isotherms; and, to perform a systems analysis on GAC and PAC for a mixture of herbicides and metabolites with initial concentrations commonly found in the natural environment. The third part was performed to predict the impact of the possible maximum contaminant levels for the metabolites on systems already treating for atrazine. Single solute Freundlich isotherms were prepared for each s-triazine and s-triazine metabolite using organic free water. Next, the s-triazine liquid phase analysis was performed using a combination of High Performance Immunoaffinity Chromatography and Reverse Phase Liquid Chromatography . The Ideal Adsorbed Solution Theory model and the Equilibrium Column Model also were used in this research. Finally, mathematical models were used to describe the GAC and PAC treatment processes.
