摘要: Batch adsorption studies were carried out for the sorption of C.I. Reactive Black 5, a reactive dye, onto high lime fly ash, obtained from Soma Thermal Power Plant (Turkey), to be low cost adsorbent. The effect various experimental parameters such as contact time, adsorbent dose and initial dye concentration investigated. Determination equilibrium concentrations was determined by UV-vis spectrophotometry analytical method. Equilibrium data fitted Freundlich Langmuir isotherm equations found well represented equation. kinetics 5 ash also studied characterize surface complexation reaction. A pseudo-second-order mechanism has been developed predict rate constant adsorption, capacity with concentration. single-stage batch adsorber design based on
