Zwitterionic glycine was employed to modify Fe/Mg-layered double hydroxides (LDH) to realize an GFe/Mg-LDH adsorbent with high adsorption capacities of oxygen-containing anions including As(V), P(V) and Cr(VI). When the Fe/Mg mole ratio was 0.02 mol/0.02 mol, the G-Fe/Mg-LDH has a good adsorption performance. The optimum adsorption pH value of G-Fe/Mg-LDH for oxygen-containing anions was 6. The selectivity of three oxygen-containing anions was Cr(VI)
