Comparative study of Mg/Al-LDH and Mg/Fe-LDH on adsorption and loss control of 2,4-dichlorophenoxyacetic acid.

ABSTRACT: Low efficiency and high surface runoff of 2,4-dichlorophenoxyacetic acid (2,4-D) from agricultural field threaten crop yield severely. Layered double hydroxides (LDH) have shown promising adsorption properties for 2,4-D. However, the comparison of two environmentally friendly LDHs (i.e. Mg/Al-LDH vs Mg/Fe-LDH) on adsorption of 2,4-D and corresponding intrinsic mechanisms are still unclear, and the studies on the leaching control of 2,4-D by LDHs in soil environment are particularly limited. In this study, Mg/Al-LDH and Mg/Fe-LDH were selected to conduct their adsorption kinetics experiment for 2,4-D combined with the characterization technology. The results showed that the adsorption capacity of Mg/Al-LDH and Mg/Fe-LDH for 2,4-D was up to 242 mg kg^-1 and 64 mg kg^-1, r
