Abstract

In this project the absorption of textile dye on commercial activated carbon is studied. The interaction between adsorbed molecules and the carbon surface were studied at different dye concentrations. The concentrations of dyes in the solution after adsorption process were determined using UV-Vis spectroscopy and the Beer-Lambert law. The Langmuir isotherm theoretical model was used in order to obtain characteristic parameters of adsorbent and adsorbate. In addition, the effects of the different dyes between the carbon surface and water hardness. pH and salinity on the absorption process were studied. In the study of (Red pro032) dye there are some of factors effected such as carbon and salinity. The absorption is affected by the type of carbon and salinity. Water hardness and pH effected in the absorption rate. The purpose of this experimental work, to determine which of these factors are most significant with the goal of establishing a model to predict dye absorbance in wastewater.
