Abstract

Due to an increase in worldwide pesticide usage, a need exists for the development of an effective removal process. An advanced oxidation process (AOP) that utilizes titanium dioxide (TiO2) with exposure to ultraviolet light is a possible treatment method. Experiments were run using an immobilized TiO2 catalyst with both a bench-scale batch reactor and pilot-scale compound parabolic collector (CPC) reactor to analyze the degradation of chlorpyrifos using UV-Visible spectroscopy, HPLC, TOC, and LCMS. The fixed-film batch and CPC reactor yielded average treatment efficiencies of 80% and 89%, respectively. A final design for a system utilizing CPC reactors to treat chlorpyrifos from storm water runoff was proposed following WPI guidelines.
