Popis: | Bisphenol A is widely used for the production of epoxy resins and polycarbonate plastics, and it has been found in many wastewaters or surface waters. Adsorption of bisphenol A on sediments sampled from several representative hydrologic stations of the Yellow River was studied, and some factors that may affect the sorption of bisphenol A were analyzed using the LC-MS/MS following solid-phase extraction. The results show that neither linear nor Freundlich isotherms is fit to the experimental data due to the high carbonate content in sediments. Bisphenol A has greater adsorption after the elimination of the carbonate in the sediment, and the adsorption of bisphenol A on the treated sediment can be described by both the linear and the Freundlich isotherms. The adsorption amount of bisphenol A is related to both the total organic carbon and dissolved organic carbon of sediments. The effects of Ca2 + and K+ on the adsorption of bisphenol A were also studied. It is found that Ca2+ and K+ showed different effects on the adsorption of bisphenol A because of their different valences. |
