Abstract
In this study, low-cost Rhamnus stone was used as adsorbents for the adsorption of Rhodamine-B (RhB) dye from aqueous solution by batch experiments under different condition of adsorbent weight, contact time, pH and initial dye concentration. Kinetic data obeyed to Ho-Mckay pseudo second order equation. Freundlich and Langmuir isotherms were used to test the equilibrium data and the results shows better fit with Langmuir isotherm with maximum adsorption capacity 39mg/g. Thermodynamic parameters show the adsorption of RhB onto Rhamnus stone was spontaneous and endothermic.
