Pomelo peel was chosen as adsorbent to treat the simulated dye wastewater with methylene blue. The research results showed the removal rate of 140mg/L methylene blue solution with 100mL could reach more than 83% under the optimum conditions, which were as follows: 0.4g pomelo peels powder, reaction temperature 30°C, pH value 8 and oscillating time 60min.Theoretical saturation absorptive capacity of pomelo peel was 133mg/g at 30°C.The whole adsorption process can be well described by the Langmuir and Temkin isothermal adsorption equation and secondary adsorption rate equations.
