Abstract
Paper industries will be using a different kind of dyes for producing various kinds of paper. Rhodamine–B (Rh-B) dye is one of the major sources of color effluents from textile and paper dyeing industries, and they cause long-term effects for on an aquatic environment. So this work mainly focused on the synthesis of carbon nanoparticles from neem leaves, characterization and its adsorption and photocatalytic action against Rh-B dye. In this study, Carbon nanoparticles (C NPs) from neem leaves were synthesized for adsorption and photo catalytic degradation of Rh-B dye used in paper industries. The synthesized carbon NPs were characterized by the powder X-Ray Diffraction and Scanning Electron Microscopy. The adsorption and photocatalytic properties of Ccarbon NPs were examined for 1 hour by studying the degradation of the Rh-B dye at every 5 minutes time interval through UV-Visible spectrophotometer. The results obtained shown that carbonC NPs acts as better adsorbents than as photo catalysts.
