Previous reported studies revealed that composite electrodes are effective and suitable for wastewater treatment applications owing to their high porosity and increased electrochemical active area. However, the critical challenges to the wider adoption of composite electrodes for environmental applications are the need to reduce the cost of electrode materials, and to improve both their long-term stability and electrocatalytic performance. This study aims to investigate the efficiency and stability of low-cost graphite/chitosan-polyvinyl chloride (C/Chi-PVC) composite electrodes for Reactive Red 4 (RR4) degradation. Toxicity of the treated RR4 wastewater also was investigated using a seed germination test.

探索高效石墨/壳聚糖-PVC复合电极在活性红4电化学降解中的潜力

先前报道的研究表明，复合电极由于其高孔隙率和增加的电化学活性面积而有效且适用于废水处理应用。然而，在环境应用中广泛采用复合电极的关键挑战是需要降低电极材料的成本，并提高其长期稳定性和电催化性能。本研究旨在研究低成本石墨/壳聚糖-聚氯乙烯 (C/Chi-PVC) 复合电极对活性红 4 (RR4) 降解的效率和稳定性。还使用种子发芽试验研究了处理过的 RR4 废水的毒性。
