|
In this research, the capacity of snail shell (Rostellaria) powder to remove basic dye (Azure c) from aqueous solution via adsorption was studied. Experiments were conducted at 298 K to know the impact of initial concentration of Azure c, contact time, pH and effect of ionic strength. The Optimum conditions for the adsorption of Azure C were performed at 0.0200 g of the adsorbent material.The maximum removal ratio was equal to 99.88 % at 5mg/L ,10min as adsorption time and 298 K . Equilibrium adsorption isotherms were investigated. The empirical data were analyzed by the Langmuir, Freundlich and Temkin models of adsorption at various temperatures (298 - 338) K. The adsorption isotherm data were suitability well to Langmuir isotherm. The calculated Thermodynamic information of the adsorption process ?G, ?H and ?S refers that the removal process occur via an adsorption process which features with spontaneous, exothermic and decrement in the randomness of the molecules of the adsorbent dye .The obtained isotherms information from the experiments were conform to the (S- curve) in its shape as in Giles classification".
