“…Among all the organic pollutants, endocrine-disrupting chemicals (EDCs) have received tremendous concern since EDCs can disrupt the endocrine system of human beings seriously if they are excessively accumulated in the internal organs [4]. Bisphenol A (BPA), a classic EDC that is commonly used in the chemical synthesis field, has been frequently detected in various water bodies, with concentrations exceeding the threshold of many national standards [5,6]. However, traditional wastewater treatment methods, including activated sludge process, adsorption, and flocculation processes, are not capable of separating BPA from water completely [7,8].…”

Herein, we loaded cobalt-based zeolite imidazolate frameworks, ZIF-67 (Co), onto commercial filter paper to prepare catalytic filter paper (ZFP) for the in situ degradation of bisphenol A (BPA) in water by activating peroxymonosulfate. The results showed that ZIF-67 (Co) was densely and uniformly distributed on the surface of the filter paper. The prepared ZFP could effectively degrade BPA in situ through a gravity-driven filtration process. Specifically, when the flow rate of the BPA solution passing through ZFP was lower than 10 mL/min, 0.02 mM of BPA could be completely degraded by ZFP. Furthermore, ZFP showed promising water matrix adaptability, which could provide promising BPA degradation efficiency in a wide pH range or in the existence of multiple anions. The scavenging tests demonstrated that both sulfate radical and hydroxyl radical were generated for BPA degradation, in which hydroxyl radical was the dominant active species. The ZFP also exhibited promising long-time use stability with a high mineralization rate. This study provides a novel method to prepare high-efficient catalyst paper for the in situ organic pollutant removal in water media via a prompt filtration process.
