Studies on Synthesized Gold and Silver Nanoparticles with Vegetable Peel Waste as Reducing Agents for the Treatment of Textile Effluent

Abstract

Nano- science is an important area of research in developing new nano-composite materials, has newlinebenefits in all major fields including medicine. Each nanoparticle size has individual physical, newlinechemical, mechanical and electrical properties. Nanoparticles have unique chemical, electronic, newlinemagnetic and optical properties due to their small size and high surface area. Chemical and physical newlinemethods for nanoparticle synthesis employed sophisticated technologies, enormous usage of energy newlinefor maintaining high temperature and pressure, harmful chemical capping and stabilizing reagent, newlinehazardous chemicals as their byproducts leads to the accumulation of toxic chemicals in the newlineenvironment. In the present research work noble metal nanoparticles like gold and silver were newlinesynthesized from the reduction of tetrachloroaurate and silver nitrate metal salts using potato, newlineradish, beetroot and combined vegetable peel waste extract as reducing agent were ecofriendly in newlinenature when compared to conventional methods. Importance has been given to the catalytic newlineapplications of gold and silver nanoparticles synthesized using vegetable peel waste in treatment of newlinedyes Methylene blue and Congo red. Studied recovery and reuse efficiency of gold and silver newlinenanoparticles by immobilizing the nanoparticles on eggshells. newline
