Activated carbon from durian shell: Preparation and characterization

A B S T R A C T Activated carbons were prepared from durian shell by chemical activation with potassium hydroxide. In order to find the optimum pore characteristics, different KOH to durian shell ratio (0.25–1.0) and activation temperature (673–923 K) was employed. The adsorption isotherm of activated carbons produced within these range of temperature and impregnation ratio is a mixture…
