Sažetak
Textile wastewater discharged after the textile dyeing and finishing processes has become a concern for the environment. Textile industry uses various types of synthetic, mostly reactive dyes, and discharges enormous amounts of highly coloured waters. An adsorption process, as sustainable textile wastewater treatment method, is one of the most commonly used and effective method for removal of dyes from coloured water. This paper deals with isothermal adsorption of reactive dye Everzol Black B on commercial powdered activated carbon. Batch mode adsorption study was carried out at three different temperatures and different periods until equilibrium was reached. The residual liquid-phase dye concentration, amount of adsorbate adsorbed, and percentage of adsorbed dye were calculated after adsorption process. In order to investigate the mechanism of dye adsorption experimental data were analysed by two kinetic models. Based on the values of dye concentrations at equilibrium, thermodynamic parameters of adsorption were also determined.
