STUDY OF BIOCHAR FROM GRO-WASTE FOR DYE ADSORPTION: CAPACITY AND KINETICS

Two biochars derived from wattle bark (BA) and coffee husks (BC) used to remove methylene blue (MB) which achieved the yield values of 33.3 % to 35.08% at 500 o C of pyrolysis. Adsorption increased with the rising of the dose until 2 g/L for BC, and 5 g/L for BA, respectively. When rising pH, the increasing trend was observed for BA, and BC, from 67 % at pH of 2 to 93% at pH of 12. The equilibrium time depended on the initial MB concentration and the MB removal accounted for over 83% at the first 30 minutes. The experiment data fits better with Avrami, and Elovich than Pseudo-first-order equation (PSO), and Pseudo-second-order model (PFO). Adsorption process comprised more than one reaction pathway including integer-kinetic order, and multiple kinetic orders or fractionary kinetic order.
