USE OF PULSED-UV PROCESSES TO DESTROY NDMA

DAVIS M.K. / LIANG S. / MIN J.H. / et al. - ARTICLE DE PERIODIQUE - 2003

The main objective of this study is to evaluate the effectiveness of pulsed-UV and pulsed-UV/H202 processes for N-nitrosodimethylamine (NDMA) removal. Pulsed-UV with a small amount of H2O2 could be used to control the reaction by-products and to inhibit the reformation of NDMA by using hydroxyl radicals generated during the photolysis of H202. In contrast, pulsed-UV with a larger amount of H202 could inhibit NDMA decay by direct photolysis.
