A comprehensive review on BPA degradation by heterogeneous Fenton-like processes

Abstract

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 miming 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 SO4•– 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.

Fabrication of core–shell AuNP@UIO-66/Au nanoparticles for in situ SERS monitoring of the degradation process

“…This results in the destruction of the benzene ring structure of CV and finally degradation into small organic molecules. 31,32 Generally, these results further verify that AuNP/UIO-66@Au is suitable for reaction monitoring using the SERS method.…”

Biogenic derived egg shell and its derivatives as solid base heterogeneous catalysts for organic transformations: a comprehensive review

“…At temperatures ranging from 310 K, 320 K and 330 K, the degradation efficiency was found to increase with increase in temperature up to 91%. 82 On building a bridge between nanomaterials and eggshell waste, Wang et al designed eggshell-supported copper oxide and used a peroxymonosulfate (PMS) activator for the removal of reactive blue 19 (RB19). The CuO/eggshell catalyst showed a high degradation efficiency of approximately 100% with 20 mg L −1 of RB19, 0.2 g L −1 of CuO/eggshell, 0.36 mM of PMS and a pH of 7.12 within 20 min.…”

Light‐Driven MXene‐Based Microrobots: Mineralization of Bisphenol A to CO2 and H2O

“…[56] However, photocatalytic degradation is regarded as the most favorable method due to its eco-friendliness, superior efficiency, relatively low cost, and straightforward operation. [57][58][59] Furthermore, traditional methods are difficult to operate and in some circumstances, cause secondary contamination. [60,61] As a result, it is critical to discover a cost-effective, efficient, and ecologically friendly approach to remove BPA from polluted water.…”
