Sustainable Approaches for Pharmaceutical Pollutant Removal: Advances in Chitosan‐Based Nanocomposite Adsorbents

ChemistrySelect, Journal Year: 2025, Volume and Issue: 10(13)

Published: April 1, 2025

Abstract The growing presence of pharmaceutical pollutants in aquatic environments poses significant threats to both human health and ecosystems. Despite their crucial role healthcare, pharmaceuticals enter water systems through various sources, making them some the most critical environmental contaminants. Traditional wastewater treatments, which are classified into physical, chemical, biological techniques, often struggle effectively remove pharmaceuticals. Among these methods, adsorption stands out as a reliable versatile approach for removing organic enhancing efficiency treatment processes. Biopolymers, particularly chitosan, gaining attention due numerous advantages, including biocompatibility, biodegradability, affordability, high capability, non‐toxicity, availability from diverse natural sources. Chitosan, hydrophilic biopolymer, can be chemically modified by incorporating nanoparticles (e.g., metal oxides, carbon‐based materials, magnetic particles) boost its efficiency. These advancements enable chitosan‐based nanocomposites range pharmaceuticals, antibiotics, analgesics, hormones, water. This review examines latest developments nanocomposite adsorbents, emphasizing fundamental mechanisms, optimization conditions, kinetic behaviors, isotherm models. factors collectively determine capturing pollutants. Moreover, underscores potential materials remediation, offering valuable insights application future research directions. Ultimately, aim this is provide insight offer an innovative effective solution challenge contamination By addressing key challenges utilizing advanced material designs, adsorbents hold great promise sustainable efficient removal systems.
