Synthesis and Properties of Molybdenum Targeted Adsorption Materials
Molybdenum targeted-adsorption material(α-BO/PMMA)was prepared by vacuum infusion of α-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 MoO22+ concentration on the adsorption properties of α-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.
