Mineralization and Biodegradability Enhancement of Low Level -Nitrophenol in Water Using Fenton’s Reagent

Volume 131, Issue 2
Abstract
This study presents the use of dissolved organic carbon (DOC) and biodegradable dissolved organic carbon (BDOC) to indicate the degree of mineralization and biodegradability (BDOC/DOC) change of a dilute -nitrophenol aqueous solution (initial DOC of 8.5 MG/L) induced by Fenton’s reagent. :DOC ratios of 1:10:1, 10:10:1, and 10:100:1 and pH of 2, 3, and 4 were tested. Mineralization of -nitrophenol of 5–35% was observed along with biodegradability increase. The best conditions for maximum mineralization were :DOC of 10:10:1 and pH of 4 while the optimum conditions for highest biodegradability increase were :DOC of 10:10:1 and pH of 3. Under the optimal conditions, the biodegradability was enhanced from 8 to 80%. More than 95% of total DOC removal and BDOC formation was observed in the first 10 min of the reaction. Results further indicated that :DOC of 10:10:1 and pH of 4 were optimal for a combination of the maximum DOC elimination and biodegradability increase.
