Abstract

Activated carbons were produced from coconut shells of tall and dwarf tree varieties.The activated carbon from the tall tree variety was initially synthesized using 1Mconcentration of each of ZnCl2, H3PO4, and KOHsolutions. From the adsorptive tests conducted using methylene blue solution, the activated carbon produced with H3PO4 gave the best absorbance and adsorptive performance. Coconut shells of dwarf tree variety were then obtained and treated with same mass of coconut shells of the tall tree variety using varied concentrations of the acid in order to determine whether the optimum concentration and temperature for producing carbon black fromthe coconut shells are distinct or similar for both varieties.Theprocess was alsomodelled using the Differential Response Method (DRM) in order to determine the yields and adsorptive performances of the activated carbons by varying the carbonization temperature and concentration. The results from experiment and the developed mathematical model were both found to be in agreement giving the optimum concentration of phosphoric acid and pH for producing activated carbon to be 0.67M and 2.07 for the tall tree variety and 1M and 1.98 for the dwarf variety at optimum temperatures in the range of 450–575∘C and 575∘C, respectively
