摘要：

The adsorption capacity was compared for the dye wastewater onto adsorbent MnO2. The effects of contact time and dosage of adsorbent were studied. The adsorption kinetics was analyzed. The results showed that MnO2 possessed higher adsorption capacity to Methylene blue than Methyl orange which the removal efficiency could reached 94.82%and 78.63% respectively under the conditions (the dosage1.2g/L, time 60min, initial dye concentration 50mg/L, pH7). The dynamical data fit well with the pseudo second order kinetic model. The MnO2 has higher Methylene blue adsorption capacity in short equilibrium times and are good alternative in wastewater treatment.
