Abstract

The treatment of industrial wastewater has gained significant attention in recent years due to its detrimental impact on the environment and public health. This study aims to explore the effectiveness of a photocatalytic hybrid system using a Chitosan-TiO2 membrane for the degradation of batik waste. The performance of the membrane was investigated through a series of experiments, evaluating its ability to remove organic pollutants and enhance the overall treatment efficiency. The morphology, as seen through SEM images, shows a rough surface that enhances photocatalytic efficiency by providing a larger surface area for reactions. The uniform distribution of TiO2 particles within the chitosan matrix is crucial for stable and efficient pollutant degradation during photocatalysis. Furthermore, Chitosan-TiO2 membranes offer a promising solution for batik wastewater treatment. They combine the benefits of chitosan's permeability and organic substance capture with TiO2's photocatalytic capabilities. This integration allows for efficient, one-step hybrid photocatalytic filtration, reducing the use of harmful chemicals and producing environmentally friendlier byproducts. Finally, AAS analysis demonstrated that the addition of TiO2 improved heavy metal degradation in batik waste, with optimal performance observed up to a 89.78% rejection rate, beyond which TiO2 agglomeration occurred.
壳聚糖-二氧化钛膜性能对光催化混合系统降解蜡染废料的影响
近年来,由于工业废水对环境和公众健康造成的不利影响,其处理问题受到了广泛关注。本研究旨在探索使用壳聚糖-二氧化钛膜的光催化混合系统降解蜡染废水的有效性。通过一系列实验对该膜的性能进行了研究,评估了其去除有机污染物和提高整体处理效率的能力。通过扫描电子显微镜(SEM)图像可以看到,膜的形态显示出粗糙的表面,通过提供更大的反应表面积来提高光催化效率。二氧化钛颗粒在壳聚糖基质中的均匀分布对于光催化过程中稳定高效地降解污染物至关重要。此外,壳聚糖-二氧化钛膜为蜡染废水处理提供了一种前景广阔的解决方案。这种膜将壳聚糖的渗透性和有机物捕捉能力与二氧化钛的光催化能力结合在一起。这种整合可实现高效、一步到位的混合光催化过滤,减少有害化学物质的使用,并产生更环保的副产品。最后,AAS 分析表明,二氧化钛的添加改善了蜡染废料中重金属的降解,最佳性能可观察到 89.78% 的剔除率,超过此值,二氧化钛就会结块。
