Study of the Ability of Flint Clay Surface in Adsorption of Ibuprofen from Solution

This research is concerned with one of applications of adsorption from solution on selected clay surface. The aim of the work is to investigate the activity of flint clay as antidote in treatment of poisoning by some drug (ibuprofen).The technique of U.V / visible spectrophotometer has been utilized for quantitative estimation of adsorption uptake of the drug by the surfaces in different conditions of temperature, and pH. Stomach environments; have been specifically taken into consideration in this study, i.e., its pH and human body temperature. The adsorption of ibuprofen from aqueous solution on clay has been studied initially in neutral media using distilled water (pH7) as a solvent at 37.5 o C.The increase in adsorption uptake of drug in acidic media may be attributed to the possible changes in the properties of clay surfaces upon lowering the pH value at the solid liquid interface. The results show a decrease in the adsorption extent of drug on clay with increasing the temperature; suggesting an exothermic adsorption process to take place on the two surfaces.
