The adsorption of Zn(II) and Cu(II) onto siderite (S) and kaolin (K) and adsorption of As(V) onto bentonite (B) was studied. The chemical modification – precipitation of MnO2 on the kaolin (KM) and siderite (SM) surface was used to improve the adsorption properties of natural materials for their application in columns. In the batch tests the higher...
