研究目的
To investigate the enhancement of photocatalytic degradation capacity of mixed industrial effluent using a modified activated charcoal/TiO2 nanocomposite catalyst.
研究成果
The study concludes that the use of a modified nanocomposite-based catalyst under ultraviolet light-emitting diode irradiation enhances the degradation efficiency of mixed industrial effluent in a less time period. The results showed significant removal of COD, BOD, chloride, and sulfate, indicating the potential of this method for wastewater treatment.
研究不足
The study focuses on the degradation of mixed industrial effluent under specific conditions using a modified nanocomposite photocatalyst. The applicability of the method to other types of wastewater or under different conditions was not explored.
1：Experimental Design and Method Selection:
The study utilized the sol–gel method for synthesizing activated charcoal/TiO2 nanocomposite catalysts. The photocatalytic degradation efficiency was evaluated under UVLED light irradiation.
2：Sample Selection and Data Sources:
Mixed industrial effluent samples were collected from CETP inlet (Gujarat, India).
3：List of Experimental Equipment and Materials:
Tetraisopropyl orthotitanate, activated charcoal powder, 2-propanol, UVLED from Shenzhen Xinxusheng Technology Co., Ltd, China.
4：Experimental Procedures and Operational Workflow:
The photocatalytic degradation was performed in a UV chamber with the nanocomposite photocatalyst. The reactor was kept on a magnetic stirrer at 500 rpm for different time intervals.
5：Data Analysis Methods:
The degradation efficiency was analyzed using physio-chemical analysis of the sample. The kinetics of the photocatalytic degradation was analyzed using pseudo-first-order reaction kinetics.
