Mesoporous lanthanum phosphate was synthesized by supramolecular self‐assembly of cetyltrimethylammonium bromide and lanthanum nitrate following digestion in phosphoric acid. TGA‐DTA, XRD and SEM were employed to study the uncalcined and calcined materials. Sorption behavior of Cr(III), Mn(II), Fe(III), Co(II), Ni(II), Cu(II), Zn(II), Cd(II), Ba(II), Hg(II) and Pb(II) cations was studied on such materials in water, 3 mol·L −1 ammonia, 0.01 mol·L −1 potassium ferrocyanide and 0.01 mol·L −1 potassium ferricyanide solutions.
