Removal of Xylenol Orange from Aqueous Solution by Adsorption on Polyurethane Foam

Samah Ali, Bushra Ghazi Alharbi


A simple, low cost and fast method for the removal of xylenol orange from wastewater using poly urethane foam. The maximum removal was obtained by studying different parameter such as pH, contact time, adsorbent dose, and drug capacity. The optimum conditions for the removal of xylenol orange at pH=10  by  using 0.1 g  of PUF with contact time 60 min and 250 rpm The experimental isotherm data was studied using Langmuir and Freundlich isotherms. The results indicate that Langmuir isotherm can describe the adsorption process with adsorption capacity (qm) equal to 0.904 mg/g and  with correlation coefficient (R2) equal to 0.972.
