Abstract

The average cost generation of activated carbon from biomaterials is
relatively low as compare to the cost of industrial prepared activated carbon,
recent experimental work mainly focuses on the low cost and efficient
substitutes to the pre-existing commercial methods and finding economical
process that can subsidize the sustainability to environment and provide
benefits for further commercial use. In this research Raw material (Rice Straw) was used to produce
activated carbon, process was initially started with washing of raw material to
eliminate dirt impurities with distilled water and de-moisturized it in an oven
for 24 hours at 105 ⁰C. Then dried mass (DM) was impregnated with
the activating agent MgCl₂ with 1:1 and kept for 2 hours at room
temperature and dried for 48 hours in an oven for activation. The treated
material was carbonized by pyrolysis process in muffle furnace for 2 hours at
550 ⁰C and the final product was kept in desiccator for further use.
Freshly produced activated carbon Surface
morphology was characterized by X-Ray diffraction (XRD), scanning of
electron microscopy (SEM) & surface functional groups were analyzed by
furrier Transform Infrared Spectroscopy (FTIR). Iodine number and methylene
blue.
