چکیده انگلیسی
Hydrothermal carbonization of biomass wastes presents a promising step in the production of cost-effective activated carbon. In the present work, mesoporous activated carbon (HAC) was prepared by the hydrothermal carbonization of rattan furniture wastes followed by NaOH activation. The textural and morphological characteristics, along with adsorption performance of prepared HAC toward methylene blue (MB) dye, were evaluated. The effects of common adsorption variables on performance resulted in a removal efficiency of 96% for the MB sample at initial concentration of 25 mg/L, solution pH of 7, 30 °C, and 8 h. The Langmuir equation showed the best isotherm data correlation, with a maximum uptake of 359 mg/g. The adsorbed amount versus time data was well fitted by a pseudo-second order kinetic model. The prepared HAC with a high surface area of 1135 m2/g and an average pore size distribution of 35.5 Ã
could be an efficient adsorbent for treatment of synthetic dyes in wastewaters.
