Abstract

Congo red (CR), one of the toxic dyes, which is extensively used for dyestuffs, textile, paper and plastic industries. CR does not easily biodegrade in aqueous medium and show harmful effect on aquatic as well as human life. In the present work adsorption studies of CR onto Sarpgandha (Rauwolfia serpentine) leaves powder (SLP) adsorbent was examined in aqueous solution at 27.5ºC with the effects of initial concentration, adsorbent dose, temperature and contact time. Highest 70.98% adsorption efficiency recorded for 20 mg/L solution concentration onto 2.5g of SLP. The applicability of Langmuir and Freundlich isotherm model was investigated, and the Freundlich adsorption isotherm model exhibited the best fit than Langmuir isotherm model with the experimental data. The kinetic data was fitted to pseudo-second-order kinetic model. The adsorption technique was found to be SLP is very useful and cost effective for a better removal of hazardous CR dye.
