Bio-based acrylate crosslinked copolymer from vegetable oil-derived N-octadecyl acrylate and acrylic acid for heavy metal ions adsorption
Heavy metal contamination of water resources is one of the most serious problems affecting human health and ecosystems. To remove heavy metal ions from polluted water, a bio-based cross-linked copolymer comprising vegetable oil-derived n-octadecyl acrylate and acrylic acid was synthesized via reversible addition-fragmentation chain transfer polymerization using multifunctional calix[4]resorcin-arene thioester as an initiator. Its amphiphilic structure, featuring both hydrophilic and hydrophobic domains, ensured efficient hazardous adsorption. Several techniques, including nuclear magnetic resonance spectroscopy, fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectroscopy, Brunauer–Emmett–Teller analysis, and thermogravimetric analysis, were used to characterize and confirm the formation of the polymeric adsorbent. This copolymer has been evaluated for its ability to remove some common risky metal cations, including cadmium, nickel, and cobalt ions from aqueous solutions, which showed high adsorption efficiency. Optimization studies were conducted to maximize ion adsorption. In addition, pseudo-first-order and pseudo-second-order models were used to analyze adsorption kinetics, and Langmuir and Freundlich models were applied to study adsorption isotherms. The thermodynamics of adsorption was also investigated. As a result, high adsorption efficiency and effective ion desorption capability emphasize its recoverability and reusability.
期刊介绍：
International Journal of Environmental Science and Technology (IJEST) is an international scholarly refereed research journal which aims to promote the theory and practice of environmental science and technology, innovation, engineering and management.
A broad outline of the journal''s scope includes: peer reviewed original research articles, case and technical reports, reviews and analyses papers, short communications and notes to the editor, in interdisciplinary information on the practice and status of research in environmental science and technology, both natural and man made.
The main aspects of research areas include, but are not exclusive to; environmental chemistry and biology, environments pollution control and abatement technology, transport and fate of pollutants in the environment, concentrations and dispersion of wastes in air, water, and soil, point and non-point sources pollution, heavy metals and organic compounds in the environment, atmospheric pollutants and trace gases, solid and hazardous waste management; soil biodegradation and bioremediation of contaminated sites; environmental impact assessment, industrial ecology, ecological and human risk assessment; improved energy management and auditing efficiency and environmental standards and criteria.
