Synthetic organic pollutants emanating continuously in the ecosystem have become a global concern because of their toxicity and persistent nature. Bisphenol A (BPA) is one such pollutant which threatens public health and safety. It is a monomer used in manufacturing plastics, polycarbonate resins, epoxy resins and is a well-recognised endocrine disruptor mimicking estrogen. BPA leaches into food and beverages stored in containers causing contamination issues. Its widespread exposure and potential toxicity is an environmental health concern. In this review, a systematic investigation has been carried out on the heterogeneous catalysts used for Fenton-like processes for BPA degradation. The Fenton-like reaction is one such reaction that is used for wastewater remediation purposes. The reaction advances through the generation of powerful oxidizing radicals like •OH and SO in the presence of a suitable catalyst. The application of various Fenton catalysts, with their distinguished morphological characteristics, oxidizing properties, toxicity analysis, and the present state of the art of BPA degradation by these catalysts, have been documented in the current work. This review also highlights a few challenges and prospects for analysing degradation products of landfill leachate.
不断在生态系统中释放的合成有机污染物因其毒性和持久性而成为全球关注的焦点。双酚 A (BPA) 就是这样一种污染物，它威胁着公众的健康和安全。它是一种用于制造塑料、聚碳酸酯树脂、环氧树脂的单体，是一种公认的具有雌激素模拟作用的内分泌干扰物。BPA 会渗出到储存在容器中的食物和饮料中，造成污染问题。其广泛的暴露和潜在的毒性是一个环境卫生问题。在这篇综述中，对用于 BPA 降解的类 Fenton 过程的异相催化剂进行了系统的研究。类 Fenton 反应是一种用于废水修复目的的反应。在合适的催化剂存在下，通过生成强大的氧化自由基，如•OH 和 SO，来推进反应。本工作记录了各种 Fenton 催化剂的应用，以及它们独特的形态特征、氧化特性、毒性分析以及这些催化剂对 BPA 降解的最新进展。本综述还强调了分析垃圾渗滤液降解产物的一些挑战和前景。
