Effect of temperature on green synthesized silver nanoparticles using water and methonol

Abstract

Industrial effluents containing dyes pose severe threat to health and environmental hazards. Conventional methods employed in treating these effluents are not effective and economical. There is a need for having alternative methods to resolve these implications. Nanoparticles (NPs) have large surface area, high adsorption properties, high diffusivity and equilibrates faster, are widely employed in treatment of effluents from textile and leather industries containing organic and inorganic dyes. Silver nanoparticles (Ag NPs) have superior physical, chemical and biological properties such as antibacterial and antifungal properties. Ag Nps are widely used to degrade hazardous dyes due to its superior properties. The properties of chosen nanoparticles, temperature and pH of the reaction mixture and the initial concentration of dye influences the efficiency of dye degradation. The rate of degradation has been reported to be faster at higher temperature due to increase in kinetics of the reaction or driven by the physical properties of nanoparticles. In this report, the effect of temperature on the nature of synthesized silver nanoparticles and its subsequent effect in the role of dye degradation has been investigated.
