Removal of As(Ⅲ) in a column reactor packed with iron-coated sand and manganese-coated sand

摘要

The applicability of manganese-coated sand (MCS) and iron-coated sand (ICS) for the treatment of As(Ⅲ) via oxidation and adsorption processes was investigated. Scanning electron microscopy (SEM) and X-ray diffraction spectroscopy (XRD) were used to observ
