Abstract
Plastic pollution is a major environmental issue, negatively impacting ecosystems, water resources, and human health. Among the various pollutants derived from the plastics industry, bisphenol A (P-BPA) is one of the most common and is frequently detected in surface water, groundwater, and even drinking water at varying concentrations around the world. This study proposes a simple and cost-effective method for removing P-BPA using activated carbon derived from agricultural waste (AC-AW) and its modified form (MAC-AW). The porous structure, high specific surface area, and various surface functional groups of AC-AW were confirmed by Scanning Electron Microscopy (SEM), Brunauer–Emmett–Teller (BET) surface area analysis, and Fourier Transform Infrared Spectroscopy (FT-IR), respectively. The maximum adsorption capacities of P-BPA at pH 6.0 were determined to be 238.09mg/g for MAC-AW and 188.67mg/g for AC-AW. Besides, MAC-AW was able to remove 95.8 and 86.1% of P-BPA from municipal and industrial wastewater, respectively. It also kept a high P-BPA removal efficiency (91%) after four reuse cycles, suggesting the potential of activated carbon derived from agricultural waste for practical application in water treatment. In addition, the adsorption mechanisms, benefits, and challenges of using AC-AW for removing P-BPA released from plastic sources were highlighted.
期刊介绍:
The Process Safety and Environmental Protection (PSEP) journal is a leading international publication that focuses on the publication of high-quality, original research papers in the field of engineering, specifically those related to the safety of industrial processes and environmental protection. The journal encourages submissions that present new developments in safety and environmental aspects, particularly those that show how research findings can be applied in process engineering design and practice.
PSEP is particularly interested in research that brings fresh perspectives to established engineering principles, identifies unsolved problems, or suggests directions for future research. The journal also values contributions that push the boundaries of traditional engineering and welcomes multidisciplinary papers.
PSEP's articles are abstracted and indexed by a range of databases and services, which helps to ensure that the journal's research is accessible and recognized in the academic and professional communities. These databases include ANTE, Chemical Abstracts, Chemical Hazards in Industry, Current Contents, Elsevier Engineering Information database, Pascal Francis, Web of Science, Scopus, Engineering Information Database EnCompass LIT (Elsevier), and INSPEC. This wide coverage facilitates the dissemination of the journal's content to a global audience interested in process safety and environmental engineering.
