The results of the impact of the [Mg(II)]/[Fe(III)] as part of layered double hydroxides on their sorption capacity with respect to phosphate-ions are presented. It is shown that the most effective for the removal of the given anions from water media within the range pH 3–9 are calcined forms of sorbents being studied with the [Mg(II)]/Fe(III)] 2 : 1 and 3 : 1. Maximum values of adsorption constitute respectively 90.9 and 91.7 mg/g.
