Gamma radiation for treatment of bisphenol A solution in presence of different additives
چکیده انگلیسی

The treatment of bisphenol A (BPA)-contaminated solution has attracted more and more interests recently. In this contribution, BPA removals using gamma radiation in presence of different additives were carried out. It can be observed that absorbed dose, BPA initial concentration, solution pH, dissolved oxygen and organic matters were the important factors in influencing BPA decomposition during gamma radiation. Based on the results of quantum chemical calculations and GC–MS analysis, we suggested BPA degradation pathway to produce ortho-position monohydroxylated BPA and meta-position monohydroxylated BPA via OH radical oxidation. In addition, gamma radiation resulted in a slight decrease in pH and TOC data of BPA-containing aqueous solution.


► We have evaluated the feasibility on BPA removal using γ-radiation.
► Monohydroxylated BPA resulting from BPA γ-radiation was identified using GC–MS.
► BPA γ-radiation was proved to be mainly controlled by OH radical oxidation.
