N-nitrosodimethylamine (NDMA), as a suspected human carcinogen, is detected in our drinking water. This project focused on photocatalytic oxidation using a UV-LED lamp. The goal of this project was to study the degradation and removal rate of NDMA from water and to compare the removal achieved to results of treatment by a mercury UV lamp. Two concentrations of anatase phase titania photocatalyst, 800 mg/L and 1200 mg/L, were tested with results showing slightly better removal by the lower concentration. Analysis by Gas Chromatography (GC) and kinetics analysis techniques yielded evidence of effective removal at a near first-order behavior.
