A Statistical Study Comparing Experimental and Theoretical Yields of Activated Carbon Prepared from Pomegranate (Punica granatum) Peels via Chemical Treatment

Abstract

Due to the great importance that activated carbon has gained through its use in combating pollution, removing dyes components, and other uses, it has been prepared in different ways. In this research, a statistical study was conducted to compare the practical and theoretical values of activated carbon yield prepared from pomegranate peels with some additives (Novolak resin and Beji asphalt) in order to improve its specifications. Since the preparation of activated carbon is controlled by a group of variables, a number of matters were tested for the possibility of finding a linear relationship based on the effect of the amount of the iodine number, density, ash content, and humidity on the yield of all prepared types of activated carbon, and considering the possibility of achieving the relationship through additional additives that can be obtained through it on carbon with a homogeneous surface and specifications. Also, finding a general mathematical relationship that brings together all the types prepared from pomegranate peels after adding new variables representing the percentages of adding asphalt to them and novolak resin used in preparation and activation. This equation makes it possible to control the proportions of the resulting yield before trying to measure, test and evaluate any of the practically calculated values such as the iodine number, density, ash content and humidity using the mathematical equation and calculating them for unknown values if the other characteristics are known. This achieves a shortening of the time period. The success of this method is evidenced by the high experimental R2 values, the low SE, and the logical variation of the variable coefficients.
