A novel type of magnetic Fe2O3/Fe3O4 heterogeneous microparticles with ellipsoidal macropores was prepared via the ethanol-water reflux and rapid combustion process. The experimental results showed that the volume of absolute ethyl alcohol and the calcination temperature were the key factors to the grain sizes and the magnetic properties, the calcination temperature largely affected the saturation magnetization and the grain size of Fe2O3/Fe3O4 heterogeneous microparticles, and the amount of absolute ethyl alcohol also tremendously affected the saturation magnetization, however, the amount of absolute ethyl alcohol affected little on the grain size. Fe2O3/Fe3O4 heterogeneous microparticles calcined at 200 °C for 1 h with absolute ethyl alcohol of 20 mL had the largest saturation magnetization of 90.1 Am2/kg.

Adsorbent Dose

Methylene blue removal by adsorption method had been done in batch method using adsorbent of used paper powder. Adsorption parameters covering adsorbent doses, contact times, pH, adsorbate concentrations and adsorption isotherm as well as desorption study of the absorbed methylene blue were evaluated. The results showed the highest adsorption of methylene blue was obtained at an optimum adsorbent dose, for 30 min at pH > 9. The maximum adsorption capacity of 30.77 mg/g was obtained with Langmuir isotherm model. While the effective methylene blue desorption on the used paper powder adsorbent was obtained c.a. 0.27 mg/g at pH 1.
