Methylene Blue Dye Degradation Using Silver Nanoparticles Synthesized from Andographis Paniculata Leaves Extract

Abstract

Today, the ejection of hazardous dyes from textile industries in water reservoirs like rivers, lakes and groundwater has become a severe problem. To remove these pollutants is challenging by classical water treatment procedures. Thus, for effluent treatment, we need a more convenient method. Here, we describe use of green synthesized silver nanoparticles in the degradation of precarious dye like methylene blue. The silver nanoparticles synthesized from leaves extract of andographis paniculata which act as a nanocatalyst. The synthesis of silver nanoparticles (AgNPs) and the reduction of silver ions are studied using UV-Visible spectroscopy (Ultraviolet-Visible spectroscopy) and FT-IR spectroscopy (Fourier Transform Infrared spectroscopy) respectively. Organic compounds are responsible for the capping and reduction of silver nanoparticles, according to Fourier Transform infrared spectra. The report accentuate that the AgNPs examined to be an effective catalyst for reduction of precarious dyes nearly 84% at 16 hrs of exposure time.
