This research aims to produce activated carbon from molasses via a chemical activation process with potassium hydroxide (KOH) and a microwave heating process which consumes less energy and provides more rapid and uniform heat distribution than a conventional heating. The obtained activated carbon was then characterized with BET SEM and FTIR. It exhibited a large specific surface area of 1631 m2/g and a total pore volume of 1.124 cm3/g consisting of mesopore and micropore. In addition the active functional groups were also found on the surface of the activated carbon. Thus it was brought for the adsorption test with methylene blue. It was found that the adsorption capacity of the activated carbon increased with time and reached the equilibrium within 8 hours. The adsorption data of the activated carbon were corresponded to Langmuir isotherm with the highest adsorption capacity of 370.37 mg/g. The adsorption kinetic of the activated carbon exhibited pseudo-second order reaction suggesting to the chemisorption phenomenon. From the thermodynamic study it revealed that the adsorption process were endothermic and spontaneous reactions.

Dyes contaminated in wastewater that negatively affecting the environment and human health. The objectives of this study to prepare activated carbon from Salacca zalacca (Sumalee) seeds activated by 36 mmol/g KOH dye solution and activated carbon ratio 20:32 ml/g for dye removal. The influents of dye removal from wastewater by Salacca zalacca (Sumalee) seeds activated carbon were investigated as initial dye concentration activated carbon and dye solution ratio and contraction time. The moisture content the iodine number the methylene blue index and the functional groups by FTIR technique of the Salacca zalacca (Sumalee) activated carbon were characterized and the kinetics adsorption were also analyzed. The results showed that the activated carbon was the microporous material the highest dye removal from wastewater was 7.50 ± 0.25 mg/g the equilibrium time was 150 min with the activated carbon to dye solution ratio of 1:500 g/ml for 200 mg/l initial concentration. The kinetics of the adsorption process can be described by a pseudo-second order model (R2 = 0.9999). When increasing the initial concentration of dyes the adsorption efficiency was increased. The amount of activated carbon increased resulting in lower adsorption efficiency and the equilibrium time was longer
