Hydrogel nanoparticle for removal of heavy metals (Zinc)

Chemical Engineering

Heavy metal contamination, especially from zinc ions (Zn²⁺), poses a serious risk to both environmental and public health due to its toxicity and persistence in ecosystems. This study investigates the synthesis, characterization, and application of hydrogel nanoparticles as a novel and efficient adsorbent for the removal of zinc ions from aqueous solutions. The nanoparticles are formulated using biocompatible polymers and crosslinking agents to form a three-dimensional, porous network with a high surface area and strong affinity for metal ions. Batch adsorption experiments are performed to assess key parameters, including pH, contact time, initial Zn²⁺ concentration, and nanoparticle dosage. The findings reveal high adsorption capacity and good reusability of the hydrogel nanoparticles, underscoring their effectiveness in water treatment. This research advances green nanotechnology approaches for environmental remediation and offers promising potential for scalable, sustainable solutions to heavy metal pollution
