Abstract

Adsorption is one of the common methods for treating dye wastewater. The existing adsorbents still have the problems of high cost, difficult disposal and secondary pollution. Agricultural and forestry wastes with low price and rich sources can be applied to the treatment of dye wastewater. The effect of bamboo leaf powder on the adsorption of methylene blue was studied. The effects of particle size, dosage, temperature, adsorption time and pH on the adsorption effect were studied. The results showed that the optimal single factors were: the particle size is less than 0.25mm, the dosage is 0.4g/100mL, the temperature is 20 ℃, the adsorption time is 50min and pH is 8. Study on the adsorption kinetics indicated that pseudo-second-order kinetic model could better describe the kinetic behaviour. Comprehensively considering the interaction among multiple factors, the optimization experiment was designed by the Optimal mode of Design-Expert software, and the factors were optimized by the response surface method. The results showed that the optimal conditions were: the dosage is 5.37g/L, the adsorption time is 65.47min, the temperature is 25.17 ℃, and pH is 6.7. The results showed that bamboo leaf is a potential natural adsorbent for methylene blue in wastewater.
