This study aims to investigate the main sources of RDOM and its properties influenced by environmental factors (such as light exposure and temperature variation). The results revealed that RDOM was mainly composed of SDOM. Temperature (–5°C, −20°C, temperature alternating, 40°C, 50°C, 60°C) induced the variation of SDOM components, altering its fluorescence characteristics, aromatic components, and hydrophobicity. And high temperature showed a more pronounced effect on SDOM components. However, temperature fluctuations had different impacts on the SDOM-mediated photodegradation of bisphenol A (BPA). Among them, only SDOM that had undergone freeze-thaw cycles exhibited a promotive effect on the photodegradation of BPA, with the most significant effect observed at −20°C. Illumination (ultraviolet light (UV) and natural light (NL)) consumed the chromophoric groups of SDOM, disrupted its intricate electron transfer structure, and reduced the production of •OH and Triplet-state dissolved organic matter (<sup>3</sup>DOM∗). So, illumination, especially UV, significantly weakened its mediating effect on the photodegradation of BPA. Based on these findings above, RDOM through temperature increase and illumination potentially leads to an inhibition of the degradation rate of organic pollutants.

This study proposed an innovative approach that using zeolite imidazole framework-8 (ZIF-8) as a cladding material for encapsulating nZVI particles. This encapsulation served to safeguard nZVI from oxidation and agglomeration. Furthermore, the ZIF-8 coating possessed suitable pore channels, allowing the migration of Cr(VI) ions towards the nZVI's surface, thereby enabling efficient reduction. The ZIF-8-coated nZVI composite (ZIF-8@nZVI) achieved a remarkable Cr(VI) removal efficiency of 98.43% under the optimized conditions. After 10 days of exposure in the aqueous solution, the efficiency remained above 84%. The uptake of Cr(VI) by ZIF-8@nZVI proceeded via a chemisorption pathway, inherently spontaneous and endothermic in character. The mechanism analysis indicated that ZIF-8 and nZVI exhibited synergistic enhancement effect on Cr(VI) removal. The protonated nitrogen groups within ZIF-8 facilitated the swift diffusion of negatively charged Cr(VI) ions to the surface of ZIF-8@nZVI.

Since MPs are present in all forms, i.e., fragments, fibres, spheres, films, and pellets; they are released into the environment from personal care products, wastewater treatment plants, laundry, etc., even in minute doses of 10 μg/ml. MPs are found in various secretions and fluids of the human body, animals, and plants. Industrial effluents were treated for MPs using conventional methods such as coagulation with flocculation, electrochemical, adsorption, advanced oxidation process, etc. Still, membrane technology is considered the best in treating wastewater, and it is eco-friendly, has low power consumption, and has a tremendous dissolution efficacy of >99%. Ceramic membrane, in particular, offers several benefits, including high-quality thermal and chemical balance, natural stamina, fouling hostility, and sturdiness. These attributes make ceramic membranes more suitable than polymeric membranes for wastewater operation. Thus, the high cost of basic materials and the need for soaring sintering temperatures have made ceramic membranes expensive. As a result, researchers are focusing on developing ceramic membranes from other cost-effective materials to decrease costs. These cost-effective ceramic membranes empower them to retain the benefits of ceramic materials while drastically lowering their manufacturing costs. This review seeks to provide a trailblazing overview of the existence, providence, and effects of MPs in the environment and also different physical, chemical, and biological treatment technologies opted to treat the MPs with emphasis on the importance of cost-effective ceramic membranes for separation of MPs from various media.</div></div>","PeriodicalId":34143,"journal":{"name":"Water Cycle","volume":"6 ","pages":"Pages 126-150"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143704972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
