摘 要:Fenton oxidation is generally inhibited in the presence of a high concentration of chloride *** study investigated the feasibility of using benzoquinone(BQ) and hydroxylamine hydrochloride(HA) as Fenton enhancers for the removal of glycerin from saline water under ambient temperature by accelerating the ferric *** was found that organics removal was not obviously affected by chloride ions of low concentration(less than 0.1 mol/L),while the mineralization rate was strongly inhibited in the presence of a large amount of chloride *** addition,ferric hydrolysis-precipitation was significantly alleviated in the presence of HA and BQ,and HA was more effective in reducing ferric ions into ferrous ions than HA,while the H_2O_2 decomposition rate was higher in the BQ-Fenton *** spin resonance analysis revealed that OH production was reduced in high salinity conditions,while it was enhanced after the addition of HA and BQ(especially HA).This study provided a possible solution to control and alleviate the inhibitory effect of chloride ions on the Fenton process for organics removal.
