Study on Adsorption of Methylene Blue on Mold/Bentonite Composite Adsorbent in Aqueous Solution

Abstract:

This study intends to explore the application of treating Methylene Blue dyeing wastewater with an inexpensive adsorbent compounded with . It studied the adsorption kinetics and adsorption thermodynamics of MB-Mold/Bentonite system. And single factor investigation were also conducted, including dosage, initial concentration, pH, stirring time and standing time. The results showed that the Methylene Blue system fitted second-order kinetics with 62.11mg/g saturated adsorption capacity. While the adsorption isotherms fitted Freundlich equation well(monolayer adsorption), with 61.49mg/g adsorption capacity. And the removal was above 99%, when the dosage of composite absorbent was 8g/L, pH was nature (5.6), stirring time was 15min and standing time was 1h .
