Enhancement Effect of CTAB in Dye Wastewater Treatment by Bentonite

Abstract:

Article Preview

. The adsorption capacity of Orange II by Cetyltrimethyl Ammonium Bromide (CTAB)+bentonite mixture system and bentonite were tested and compared. The influence factors on removal rate of Orange II such as surfactant, the pH, the contact time and temperature were studied. The results showed that the presence of cationic surfactant such as CTAB could greatly enhance the removal efficiency compared with the system only bentonite supplied. The results showed that the highest removal rate of Orange II appeared on pH<3, and when the pH value was from 3 to 5, the removal rate would drop 30%-50%.The effect of reaction temperature on the Orange II removal was then discussed, showed that the removal rate of Orange II descended 5%-10% when the temperature was higher than 25°C.
