Studies on biosorption and Photocatalytic degradation of Textile dyes using silver Nanoparticles

Abstract

Nanotechnology is an emerging field of technology in the pasture newlineof environmental science The discharge of coloured waste waters into waterbodies newlineis a serious environmental and public health problem The release of newlinedyes into the receiving water bodies is deleterious due to their color and newlinenondegradation Therefore it becomes imperative to completely degrade newlinethese organic compounds before their discharge It is conquered by newlinebiosorption and photocatalytic degradation process the valuable promising newlinetechniques for the degradation of organic pollutants In the present study newlineCongo Red CR and Direct Brown 1DB 1 dye effluent were collected from newlinetextile mill and studied for the degradation process newlineCurrently there is a growing need to develop environmentally newlinebenign nanoparticle synthesis process that does not use toxic chemicals in the newlinesynthesis protocols Synthesis of nanomaterials by biological approach is newlineinnovative cheaper and environmental friendly and requires less labor In this newlineaspect the present study is focused on the synthesis of silver nanoparticles newlinefrom the extracts of Ulva lactuca Characterization of the samples was newlineperformed by UV Visible Spectroscopy UV Vis FourierTransform Infrared newlineSpectroscopy FTIR Scanning Electron Microscopy SEM and Xray newlineDiffraction XRD methods It was found that spherical shaped nanoparticles newlineof size 40 50nm were found in SEM Altogether extracts from seaweed were newlinescreened by FT IR prediction to reveal chemical functional groups present newline newline
