Direct plant-surfactant based impregnated activated carbon for adsorption of reactive dye

In textile industry, there is major problem concerning colour effluent in ‘excess with serious consequences to human health and environment. In this work, surfactant impregnated activated carbon has been chosen as the adsorbent in the adsorption process. The aim of this study is to characterized of critical micelle concentration (CMC) of plant-based surfactant and activated carbon and to investigate the direct impregnation plant-based surfactant on activated carbon. The suspension was prepared by using direct impregnated plant based surfactant method. The best reacting condition was found to be at 125 mg/L surfactant loading with 88.56% of RB4 removal efficiency. Moreover, the ideal temperature for process was found to be at 40°C with highest percentage of removal at rate 52.84% and pH value was at pH 7 with 98.41% removal
