Preparation of Micro and Nano Activated Carbon from Waste Cone Seeds by Thermal Carbonization and Microwave Radiation

Abstract

     This research work involves the preparation of nano activated carbon and macro activated carbon from corn seeds with a various mixing ratio of potassium hydroxide (1:0, 1:0.2, 1:0.4, 1:0.6, 1:0.8 and 1:1) % using thermal and micro radiation carbonization to identify the best mixing ratio. At study to confirmed that the efficiency and effectiveness of the prepared of activated carbon samples increase when ratio potassium hydroxide increase with a thermal and micro radiation carbonization was used. The study of samples external surface area was performed via studying the adsorption of methylene blue from their aqueous solution, also measured the internal surface area was performed via studying the adsorption of iodine from their aqueous solution.  Measurement of density and humidity content were also been studied. To determine the efficiency and effectivity prepared samples. The samples were characterized by atomic force microscope (AFM), scanning electron microscopy (SEM).
