Abstract
The present investigation deals with the utilization of Lemna minor algae as an adsorbents for the removal of Acid Red88 (AR88) dye from aqueous solution. A series of experiments were conducted in a batch system to evaluate the effect of system variables. The effect of pH, initial dye concentration, dose of adsorbents and contact time were considered. Under optimum condition (pH 3, contact time 75 min, adsorbent dose 6 g/L and AR88 concentration 25mg/L), application by Lemna minor was able to remove 98% of AR88from aqueous solutions. The equilibrium data is best fitted on Langmuir isotherm and the adsorption kinetic model follows pseudo-second model. The obtained results showed that the dried Lemna minor can be used as a high efficiency and low-cost adsorbent to treat of textile effluents.
Keywords: Lemna minor, Acid Red88 dye, Isotherm’s model, Adsorption and Kinetics
