A series of goethite-modified montmorillonite (GMt) materials was synthesized for the amelioration of cationic
cadmium (Cd) and anionic arsenic (As) complex contaminants in soil and water bodies. The results showed that
goethite (Gt) was successfully loaded onto the surface of montmorillonite (Mt), which possessed more functional
groups (such as Fe–O, and Fe–OH) and a larger specific surface area. GMt-0.5 (Mt loaded with Gt at a ratio of
0.5:1) showed the highest adsorption capacity for Cd(II) and As(III) with the maximum of 50.61 mg/g and 57.58
mg/g, respectively. The removal rate of Cd(II) was highly pH dependent, while the removal rate of As(III)
showed little dependence on pH. The goethite on montmorillonite might contribute to the formation of surface
complexes with As(III) and oxidation of As(III) to As(V). In the binary system, both, synergistic and competitive
adsorption existed simultaneously. Importantly, in the binary system, the removal of As(III) was more favorable...
because of the electrostatic interaction, formation of a ternary complex, and co-precipitation. In addition, the
amendment of GMt-0.5 significantly reduced the availability of Cd and As in the soil. This study suggests that
GMt-0.5 is a promising candidate for the simultaneous immobilization of metal (loid)s in both, aqueous solution
and mine soil.
