| Abstract: | Nano-manganese dioxide has been prepared by reduction of potassium permanganate with ethanol as re- ductant, and the structure of the as-prepared product has been characterized by energy disperse spectroscopy （EDS） and scanning electron microscopy（SEM）. The nano materials were used as adsorbent to study the kinetics and ad- sorption equilibrium for adsorption of methylene blue. The results showed that the product was irregular-shaped nanoparticles; the adsorption equilibrium was more in line with the Langmuir isotherm model; and the maximum -1 adsorption capacity was 228.31 mg g |
