Article history: Received 20 March 2019 Accepted 29 April 2019 Available online 04 June 2019 Lignosulfonate doped poly(o-anisidine) and poly(o-anisidine)/lignosulfonate polymer composite protected silver nanoparticles (AgNPs) were synthesized by interfacial polymerization method by mixing of an equal molar ratio of o-anisidine and lignosulfonate using silver nitrite as oxidizing agent. The polymerization reaction was carried out under reflux condition at 80 °C for 3 hours. The resulting AgNPs nanocomposite was isolated and then characterized by using various instrument method including UV-visible spectroscopy, FT-IR, and FE-SEM analysis. The catalytic behaviour of the polymer protected silver nanoparticle was studied for the reduction of 4-nitrophenol (4-NP) and textile dyes like methylene blue (MB) and Congo Red. The reduction of 4-nitrophenol using AgNPs/poly(o-anisidine) nanocomposite reaction follow the pseudo first order kinetics and the resulting rate constant was found to be 10 min-1 for 4.0×10-4 M concentration of 4-NP using 10 mg/L of catalyst. On the other hand, the catalytic behaviour of the nanocomposite was investigated toward the degradation of some of the textile dyes such as MB and Congo Red. The percentage of degradation of dye was monitored by UV-visible spectral studies and found to be superior to the other catalyst used for the degradation studies. The present method was employed for the effective removal of textile dyes and reduction of 4-nitrophenol with a minimum amount of catalyst.
