A layered double hydroxide of magnesium and aluminum was obtained by solid-phase synthesis.It was found that it has a predominantly mesoporous structure with cylindrical and wedge-shaped pores, as well as a specific surface area of 50 m2/g. The process of phosphate ion sorption by a synthesized sample is studied. Processing of experimental data on the Freundlich and Langmuir sorption equations showed that the process is described fairly accurately by the Langmuir monomolecular adsorption equation. The capacity of the adsorption monolayer of the synthesized sample with respect to the РО43--ion and the adsorption equilibrium constant are calculated.
