摘要
研究了采用真空灌注法将α-安息香肟(α-BO)固载在多孔甲基丙烯酸酯聚合物载体(PMMA-DVB)中制备钼的靶向吸附材料(α-BO/PMMA),通过红外光谱、元素分析、热重分析及光学显微镜等手段对其进行结构表征,并考察了酸种类、H^(+)浓度、接触时间及吸附平衡时溶液中MoO_(2)^(2+)浓度对α-BO/PMMA吸附性能的影响。结果表明:α-BO/PMMA对钼的吸附受酸度影响较大,在0.1 mol/L的盐酸介质中吸附量最高,最大吸附量为29.8 mg/g,该材料可有效分离提取钼。
Molybdenum targeted-adsorption material(α-BO/PMMA)was prepared by vacuum infusion ofα-benzoxime(α-BO)in porous poly-methacrylate carrier(PMMA-DVB),and its structure was characterized by infrared spectroscopy,elemental analysis,thermogravimetric analysis and optical microscopy.The effects of acid type,H+concentration,contact time and MoO 2+2 concentration on the adsorption properties ofα-BO/PMMA were investigated.The results show that the adsorption capacity ofα-BO/PMMA on molybdenum is greatly affected by acidity,and the adsorption capacity is the highest in 0.1 mol/L hydrochloric acid medium,and the maximum adsorption capacity is 29.8 mg/g.The material can effectively separate and extract molybdenum.
