改性有机膨润土对橙黄Ⅱ的吸附与光催化降解
The adsorption and photocatalytic degradation properties of modified bentonite on orange Ⅱ
摘要
Abstract
The organobentonite-supported photosensitive complex of iron-phthalocyanine catalyst was prepared by sodium bentonite from Jurong of Jiangsu Province. Its structure was confirmed by Fourier transform infrared spectroscopy (FTIR) and X ray diffraction (XRD) characterization. We studied the adsorption and degradation performance of the catalyst on orange Ⅱ dye wastewater. The results show that the decolorization efficiency is up to 98.6% at pH of 6-9,the dosage of 0.15 g,adsorption time of 30 minutes and 50 mL of 60 mg·L-1 orange Ⅱdye wastewater. After adsorption equilibrium,through filtering,adding 50 mL 20 mg·L-1 orang Ⅱ solution,mixing for 1.5 hours at pH of 6-9 and under UV light,the decolorization rate can reach 98.1%. In addition,the catalyst can be recycled. Thus,this catalyst has a good effect on the adsorption and degradation of orange Ⅱdye.关键词
