Preparation of new nano magnetic material Fe3O4@g-C3N4 and good adsorption performance on uranium ion
A new nano magnetic material Fe3O4@g-C3N4 was prepared by deposition reduction method,which performed good adsorption performance to uranium ion.Characterization results showed that the g-C3N4 particles were wrapped around the nano magnetic Fe3O4 particles,and the textural properties of this material was improved,so the adsorption performance to uranium ion was good.Adsorption experiments of this material demonstrated that the optimum pH value was 10,the optimum mass of adsorbent was 6.5 mg and the optimum adsorption time was 150 min in the initial concentration of 140 mg/L uranium ion solution system,and the maximum adsorption capacity was up to 352.1 mg/g and the maximum adsorption rate was more than 90%.
