Background: Water pollution from new contaminants like pharmaceuticals, pesticides, dyes, and heavy metals is a big problem around the world because it harms both ecosystems and human health. These micro-pollutants are chemically stable and do not break down easily, so standard wastewater treatment methods are not very good at getting rid of them completely.
Purpose and Objectives: This study aims to create and assess bio-inspired magnetic nanocomposites as a sustainable and effective solution for the targeted elimination of emerging contaminants from aquatic systems. The goal is to create an eco-friendly adsorbent that is highly efficient, selective, and reusable, which will help improve green water purification technologies.
Methodology: The nanocomposites were made by combining biodegradable biopolymers with magnetic nanoparticles to make them easy to recover using magnetic separation. We used X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), and vibrating sample magnetometry (VSM) to figure out the structural, functional, and magnetic properties of the materials we made. Batch adsorption experiments were conducted to evaluate contaminant removal efficiency under different pH, temperature, and concentration conditions.
Results: The bio-inspired magnetic nanocomposites showed great ability to adsorb, pick out contaminants, and be recycled many times. The magnetic part made it easy to recover without losing much performance, which showed that they could be used again and again in water purification systems.
Conclusion and Significance: The results show that bio-inspired magnetic nanocomposites are a promising type of sustainable nanomaterial for cleaning up the environment. Their better performance supports the creation of new water treatment technologies and is in line with the United Nations Sustainable Development Goal 6 (Clean Water and Sanitation).
