Removing of Thymol Blue From Aqueous Solutions by Pomegranate Peel.

In this study the pomegranate peel were used to removal of thymol blue from its aqueous solutions, after activation at 500 ºC. Different concentrations of thymol blue used. Different parameters were applied including (effect of dose, effect of adsorption time, effect of pH value).The extent of dye removal increased with increase contact time. An acidic pH is suitable for increased adsorption of dye. The Langmuir isotherm was calculated at the optimum conditions. According to Langmuir isotherm, the mono layer saturation capacity (qm) is 5.28 mg/g. The study concluded that the activated pomegranate peel gone fruitful adsorption results to removal of thymol blue and it could be recommended to using it in other studies of adsorption
