Green-Synthesized Silver Nanoparticles Catalytic Efficiency for Disintegrating Common Industrial Dyes in Wastewater Compared to Chemically Synthesized Silver Nanoparticles

The study aims to help with clearing the waterways from any hazardous dyes that run off from industrial waste. Nanotechnology is being used for wastewater remediation. This process requires the comparison of green and chemical synthesized silver nanoparticles, posing the question of whether biological capping agents provide a measurable performance advantage. The methodology describes an experimental design which outlines the green synthesis process using plant extracts and chemical reduction using agents like sodium borohydride. The nano characterization was given, which described the structure, size, and shape. While the characterization was given, a spectrophotometer was used to assess the degradation of dyes like methylene blue. The results and discussion analyzed the kinetic data, highlighting that green synthesized AgNPs often achieved higher degradation rates compared to chemical synthesis. Green synthesis was shown to achieve degradation efficiencies exceeding 90%, usually in shorter timeframes. The green synthesis performance had higher efficiency due to the organic molecules from the plant extracts. These organic molecules act as effective stabilizers. Finally, it was concluded that the bio-based synthesis is eco-friendly and technologically superior. It emphasizes the recyclability of these nanocatalysts and their potential for seamless integration into large-scale, sustainable industrial water treatment systems.
