Dec 01, 2020The manganese sand was firstly collected to stack in a 500 mL Erlenmeyer flask, sonicated for 15 s, and then suspended for 15 s. The pretreatment was repeated four times before the turbid liquid was obtained. The sample was then dried in a constant temperature oven (60 C), and was finally ground by the 100 mesh screen into a powdery manganese

We examine how the processes of advection, dispersion, oxidation-reduction, and adsorption combine to affect the transport of chromium through columns packed with pyrolusite (beta-MnO2)-coated sand. We find that beta-MnO2 effectively oxidizes Cr(III) to Cr(VI) and that the extent of oxidation is sensitive to changes in pH, pore water velocity
