Kinetic studies of Ni(II) ions adsorption from aqueous solutions using the blast furnace slag (BF slag)

Abstract In this work, we used the blast furnace slag for the nickel adsorption in aqueous solution. The physico-chemical characterization showed that the BF slag consists mainly of the silica, lime, and alumina. The specific surface area of the BF slag grains is of the order of 275.8 m2/g. The opti...
