Removal of rhodamine B from aqueous solution by almond shell biosorbent
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2012, Vol 2, Issue 9
Abstract
In the present study, the use of almond shell (Prunus dulcis) biosorbent has been investigated to remove the Rhodamine B from aqueous solutions. Almond shell has been selected as an adsorbent because of advantages such as high adsorption capacity, non toxicity, availability and low cost. The effects of contact time, initial dye concentration, adsorbent dosage, particle size and solution pH were studied. The results showed that the removal efficiency increased by increasing contact time, adsorbent dosage and initial dye concentration. In addition, the adsorption was dependant to solution pH and the maximum adsorption was observed at a solution pH of 2.0. The Langmuir, Freundlich and Temkin isotherms were used to describe the adsorption equilibrium data. Freundlich equation fits the experimental data better than the Langmuir and Timken equations do.
