研究目的
To provide an efficient photocatalytic material for treatment of uranium wastewater under visible light.
研究成果
The mGO/g-C3N4 nanocomposite showed high photocatalytic activity, reusability, and reduction selectivity for U(VI) under visible LED light irradiation, with a high extraction capacity of 2880.6 mg/g. The mechanism study indicated that U(VI) was converted to metastudtite during the photoreduction process, suggesting mGCN as a promising material for uranium wastewater treatment.
研究不足
The study does not address the long-term stability of the mGCN nanocomposite under continuous operation or its performance in real wastewater conditions with complex matrices.
1：Experimental Design and Method Selection:
The study involved the preparation of magnetic graphene oxide decorated graphitic carbon nitride (mGO/g-C3N4) nanocomposite and its application for photocatalytic reduction of U(VI) in wastewater under visible LED light irradiation.
2：Sample Selection and Data Sources:
Uranium solution was obtained by dissolving UO2(NO3)2?6H2O in deionized water. The mGO and g-C3N4 were synthesized according to published literatures.
3：List of Experimental Equipment and Materials:
Instruments used included TEM, XPS, XRD, and EPR for characterization, and a glass bottle equipped with an 8 W LED lamp for photocatalytic tests.
4：Experimental Procedures and Operational Workflow:
The photocatalytic tests involved mixing mGCN, methanol, and U(VI) solution in a glass bottle, irradiating under visible LED light, and measuring U(VI) concentration by Arsenazo III spectrophotometric method.
5：Data Analysis Methods:
The data were analyzed to evaluate the photocatalytic performance, stability, and selectivity of mGCN for U(VI) removal.
