Abstract

Investigates two aqueous oxidation technologies, advanced photocatalytic oxidation and phase-transfer catalysis, for the removal of disinfection by-product (DBP) precursors. Shows that while phase-transfer catalysis is effective for the removal of specific organic compounds, photocatalytic oxidation is more effective for DBP precursor removal. Also estimates the cost and determines the rate and degree of destruction of DBP precursors. Published in 1993.
