1. Introduction

Copper is a common pollutant in water sources due to its extensive use in various industries. When copper enters water bodies, it can negatively impact aquatic life and human health. High concentrations of copper can damage the gills, scales, and reproductive organs of fish, impairing their ability to survive and reproduce. Copper contamination in drinking water can cause health issues such as stomach cramps, nausea, and liver and kidney damage. Copper can also react with water to form compounds that alter the color, taste, and odor of water, making it aesthetically unappealing. Therefore, effective removal of copper from water sources is critical for the protection of both human health and the environment. Several methods are available for the removal of copper from water, including chemical precipitation, ion exchange, adsorption, and membrane filtration [1,2,3]. Among these methods, adsorption using polymer composite beads has gained significant attention due to its effectiveness, simplicity, and cost-efficiency. Alginate-based polymer composite beads have been developed as an effective method for copper removal from water sources. These beads consist of alginate, a biopolymer derived from seaweed, and other materials such as chitosan or activated carbon, composite inorganic–organic, which enhance their copper adsorption capabilities. The composite beads have a high surface area and can be easily regenerated for multiple cycles of use. The adsorption process is dependent on factors such as pH, temperature, and contact time, and can be optimized to achieve maximum copper removal efficiency. Overall, alginate-based polymer composite beads offer a promising solution for the efficient removal of copper from water, with potential applications in wastewater treatment and environmental remediation. The main purpose of the work is to develop and evaluate the efficacy of alginate-based polymer composite beads for the removal of copper from water sources.

2. Materials and Method

In this study, alginate and inorganic–organic composite beads were synthesized through an efficient and innovative process.

3. Results

Physical experiments were performed using X-Ray Diffraction (XRD). In addition, Fourier-Transform Infrared Spectroscopy (FTIR) and Thermal Gravimetric Analysis (TGA) were used to evaluate the chemical composition and thermal properties of the adsorbents. The adsorption capacity of composite polymeric beads was determined and analyzed using Atomic Absorption Spectroscopy (AAS).

4. Conclusions

The new polymer biocomposite beads exhibited outstanding copper adsorption capabilities and can serve as promising materials for environmental remediation.
