Combined with the percentage content of each element measured by XPS full spectrum analysis in Table S1, it showed that the relative content of Cl element in Mg/Al-LDH after adsorbing 2,4-D (pH = 5, 7, and 8) was higher than Mg/Al-LDH distinctly, and had an increasing trend with the decrease of pH.
