Biosorption of acid blue 113 dyes using dried Lemna minor biomass
Journal Title: Scientific Journal of Environmental Sciences - Year 2016, Vol 5, Issue 1
Abstract
Industrial wastewater is one of the major environmental pollutants. Discharge of the colorful industrial waste into the receptive waters leads to eutrophication and has mutagenic and carcinogenic properties. Therefore, the aim of this study was to investigate the removal of acid blue 113 (AB113) from aqueous solutions by dried Lemna minor. The experimental data were analyzed by the Langmuir, Freundlich, Temkin and Harkins- Jura isotherm models. Equilibrium data fitted well to the Langmuir model with a maximum adsorption capacity of 59.96 mg/g at temperature 333 K. The dimensionless separation factor RL revealed the favorable nature of the isotherm of the AB113-Lemna minor system. The pseudo-second-order kinetic model best described the adsorption process. The adsorption capacity increases with increasing temperature then the adsorption is an endothermic process. The results proved that the Lemna minor was an effective adsorbent for removal of AB113 from aqueous.
