Microporous carbon material from fish waste for removal of methylene blue from wastewater

Abstract

Microporous fish waste-based activated carbon material (MFC) was prepared, with a large surface area of 2,193.52 m2/g a pore size of 2.67 nm and micropore and total pore volumes of 0.9168 cm3/g and 0.9975 cm3/g respectively. Adsorption efficiency of MFC was investigated by removal of methylene blue dye from wastewater. The Langmuir model and pseudo-second-order kinetics adequately described the adsorption process. MFC exhibited a high adsorption capacity of 476.19 mg/g at 30 °C, and reached equilibrium within 1 h. MFC could be an efficient and low-cost adsorbent for cationic dye removal during wastewater treatment.
