Abstract

This study is concerned with the adsorption of Congo red from solution on acrylic acid-co-[2-[2- (benzimidazole) azo]-3-methyl-4-nitro phenol] composite (AA-co-L2H ). The purpose of this study into the search for an active surface to be used to remove dyes from wastewater. FTIR and SEM-EDX characterized the morphology and chemical structure of prepared samples. UV-vis. spectrophotometric technique has been used to produce quantitative adsorption at different conditions of time, temperature and concentration of dyes. The calculated data were in accordance with Langmuir equation and the adsorption isotherms are of L-curve. The results obtained show greater removal uptake of dye on composite. The calculated data were in accordance with Langmuir equation and the adsorption isotherms are of L-curve. The results obtained show greater removal uptake of dye on composite. The adsorption was a function of temperature (10, 20 and 30oC). The extent of adsorption of Congo red on the composite was found to increase with decreasing temperature (endothermic process). The basic thermodynamic functions have also been calculated.
