Evaluation of the Influence of Salt Treatment on the Structure of Pyrolyzed Periwinkle Shell

This paper investigates the effect of use zinc chloride in varying impregnation ratios ranging between 0.1 and 1.5 to chemically activate carbonized periwinkle shells. studies to characterize the activated carbon were conducted at ambient conditions. the experimental results revealed that the impregnation ratio at 1.0 gave the optimum values for parameters such as iodine number and porosity; and minimum values for parameters like ph and moisture content which represent properties for characterizing maximum adsorption. this study successfully demonstrates the potential of zncl2 can be used as an activating agent for producing high quality activated carbon which overall has the capacity to impact positively on the quality of the environment.
