Glutamate hydrochloride ionic liquid-assisted preparation of nano-zirconia and its adsorption properties
Objective:this paper mainly studies the preparation and adsorption properties of glutamic acid hydrochloride ionic liquid as a green template assisted nano-zirconia.Methods:using the green and environmentally friendly glutamate hydrochloride ionic liquid as a template agent,combined with the reflux-hydrothermal method,nano-zirconia was synthesized,and its microscopic morphology and crystallization properties were explored;the effect of nano-zirconia on the adsorption performance of organic dye methylene blue under different conditions such as hydrothermal temperature and adsorbent dosage.Result:the nano-zirconia prepared at a hydrothermal temperature of 150℃has high-efficiency adsorption performance,and its removal rate is up to 96%.When 0.03 g of adsorbent is added,the nano-zirconia can absorb 10 mg/L methylene blue solution in a dark environment for 10 minutes after stirring,the removal rate of methylene blue reached 97%.Conclusion:the nano-zirconia prepared by this method has a very good adsorption effect on the organic dye MB in wastewater.
