摘要

The pollution of water by heavy metals is a severe problem to the environment and human health, as these pollutants are toxic, persistent, and can be absorbed by living organisms throughout the food chain. This study involves the synthesis, characterization, and application of a new Artemisia Vulgaris Hydrogel—Acrylic Acid copolymer (AVH-co-AA) as an efficient and sustainable sorbent for Cu(II),and Co(II) ions removal from aqueous solutions. Hydrogel was synthesized by a simple green approach using Artemisia Vulgaris seed extract as natural precursor, acrylic acid (AA) as monomer, and N, N′-methylene bisacrylamide (MBA) as cross-linker. Fourier Transform Infrared Spectroscopy (FTIR), Thermo Gravimetric Analysis (TGA), X-ray Diffraction (XRD), and Scanning Electron Microscope (SEM) were used to characterize the chemical and structural nature of the copolymer, which suggested successful polymerization, functional groups responsible for binding metal cations, and a porous landscape suitable for adsorption applications. High dynamic adsorption capacity was demonstrated in fixed-bed column tests, where breakthrough behavior was influenced by influent concentration, bed height, and flow rate. The Thomas and Yoon-Nelson models accurately described column kinetics, demonstrating dependable and predictable performance. Copolymer maintained high removal efficiency over multiple adsorption–desorption cycles, confirming its reusability and stability. Hence, this AVH-co-AA copolymer is presented as a green, cost-effective, and highly active adsorbent for the effective removal of heavy metals and may thus provide a promising approach toward water purification and environmental protection.
