Use of Iraqi Cherry Seeds in the Removal of Paracetamol and Atenolol Medicines from Their Aqueous Solutions

Abstract: This study describes using Iraqi cherry seeds surfaces (ICS) in the removal of paracetamol (PL) and atenolol (AL) medicines from their aqueous solutions via adsorption on the CSS. The time of adsorption equilibrium for the PL medicine was 2 hours and that for AL was one hour. The following of these medicines in their aqueous solutions were conducted using UV-Visible spectrophotometer. It was found that the optimum weight for PL was 0.1 g and it was for AL 0.05 g. Adsorption capacities for these medicines were ranged from 1.155 to 1.430 mg/g at temperature range from 313 to 333 K and pH values 2-14. Both of Freundlich and Langmuir adsorption isotherms were investigated. Thermodynamic parameters such as enthalpy H, Gibbs free energy G and change in the entropy S for adsorption of these medicines were also performed. The negative values for H indicate that, adsorption processes were exothermic, and the positive values of G indicate that, it was non-spontaneous process. Also the negative value of S, indicates that there was reduction in the entropy for the adsorption processes. This study showed that removal of AL on the ICS was more efficient than that for PL under the same reaction conditions.
