Abstract

Due to the important application of the reduced forms of nitro aromatic compounds in pharmacy, agriculture, biomedicine and many other industries, novel catalyst systems that can operate in very different environments are of great significance. In this respect nanocomposite hydrpgels based on pectin copolymerized with poly(vinyl alcohol) and poly acrylamide embedded with various metal nanoparticles were prepared by the effect of radiation and examined as catalyst for reduction of nitrophenols. The swelling ability of the prepared pectin (poly vinyl alcohol-co-polyacrylamide) hydrogel was briefly studied to confirm the optimum conditions selected. The prepared hydrogels and nanocomposite hydrogels were examined by various important techniques to prove the formation of metal nanoparticles as EDX, and transmission electron microscopy. Different parameters that affect the reduction process, such as effect of different compositions of hydrogel, effect of different metal nano-particles on reduction and the time taken to finish the reduction of 2-nitrophenol to 2-aminophenol, NaBH4 concentration, temperature and concentration of 2-NP are studied and evaluated.
