The Study of the Adsorption of some Carboxylic Acid which contain Hydroxyl group at α-Carbon

Abstract

This study involved the adsorption of some carboxylic acid (glycolic ,mandilic , benzilic acid ) on activated carbon which was prepared by chemical treatment .The percentage of adsorption , adsorption isotherms and their application were also studied such as freundlich and lagmuir isotherms . Also , we studied the effect of aromatic ring on the ability of adsorption of these carboxylic acid at room temperature. The result of this study improved that the increase inthe numberofthe aromatic ring in the structure of the carboxylic acid leads to a decreas of thepercentage of the adsorptionwere as the percentage of theadsorption in the organic acid that one has aromatic ring is greater than the carboxylic acid which don’t have anyaromatic ring.
