Abstract
The industrial use of plastic materials has led to the production of microplastics, posing significant environmental risks. Microplastic pollution, especially in water systems, has prompted efforts to develop effective removal methods. Therefore, the purpose of this study is devoted to accomplish a novel comparative assessment analysis for the efficacy of two distinct nanosized biochars in removal of polystyrene microplastics (PS-MPs) from aquatic systems by using the batch removal mode. The two selected nanosized biochars, denoted as PAB-NB and AL-NB, were derived from the pyrolysis of pineapple peels and artichoke leaves, respectively. Characterization techniques confirmed the composition and surface properties of the nanobiosorbents. Results showed that both PAB-NB and AL-NB exhibited efficient removal of PS-MPs, with AL-NB demonstrating slightly higher removal capacity. Adsorption processes were found to follow Langmuir monolayer and Freundlich multilayer formations on PAB-NB and AL-NB, respectively. Kinetic studies suggested pseudo1st and pseudo-2nd order models for AL-NB and PAB-NB, respectively. At pH 2.0, both nanobiosorbents showed high removal rates, indicating neutralization of surface charges. These findings suggest that renewable nanobiosorbents derived from biomass wastes, free from metallic contaminants, hold promise for effective removal of polystyrene pollutants, offering a sustainable solution to prevent microplastic pollution in water systems.
期刊介绍：
Environmental Nanotechnology, Monitoring and Management is a journal devoted to the publication of peer reviewed original research on environmental nanotechnologies, monitoring studies and management for water, soil , waste and human health samples. Critical review articles, short communications and scientific policy briefs are also welcome. The journal will include all environmental matrices except air. Nanomaterials were suggested as efficient cost-effective and environmental friendly alternative to existing treatment materials, from the standpoints of both resource conservation and environmental remediation. The journal aims to receive papers in the field of nanotechnology covering; Developments of new nanosorbents for: •Groundwater, drinking water and wastewater treatment •Remediation of contaminated sites •Assessment of novel nanotechnologies including sustainability and life cycle implications Monitoring and Management papers should cover the fields of: •Novel analytical methods applied to environmental and health samples •Fate and transport of pollutants in the environment •Case studies covering environmental monitoring and public health •Water and soil prevention and legislation •Industrial and hazardous waste- legislation, characterisation, management practices, minimization, treatment and disposal •Environmental management and remediation
