EFFECT OF TEMPERATURE ON ACID ACTIVATED CLAY

ABSTRACT

The effect of temperature on acid activated clay was investigated. The clay obtained from Gehaku, Kogi State, was crushed with the aid of a ceramic mortar and pestle, and afterwards ground in a ceramic plate to ensure that the clay was properly crushed, then sieved to obtain the fine clay particles. The clay fine samples were put in a crucible and oven dried at 105oC110oC to remove moisture. The clay samples were mixed with 30% v/v Hydrochloric acid solution, then afterwards agitated mechanically for twenty-four hours, filtered and thoroughly washed with distilled deionized water until no chloride ion was detected. Thereafter the acidified clay samples were filtered and oven dried at 105oC-110oC, and then calcined at 200OC and 400oC in a furnace respectively. This clay samples were analysed using X-ray diffractometer (XRD), Scanning electron microscope with elemental analysis (Energy disperse X-ray), Brunauer-Emmett-Teller (BET) and Fourier transform infrared spectroscopy (FT-IR), and the analysis showed the mineralogical component, surface topology, surface area, pore volume, and adsorption frequencies of the clay.
