Nanocrystalline magnesium silicate with high surface area has been synthesized by precipitation method using ammonium hydroxide and different surfactants. The results show that the anionic surfactant has a significant effect on the synthesis of nanocrystals. The method makes efficient use of stabilizing surfactant, and the nanocrystals show higher sorption efficiency and chemical stability. Transmission electron microscopy (TEM) shows a nanostructure consisting of different shapes according to different surfactants. According to the results of distribution coefficient on different silicate nanoparticles which applied in the polluted water in Egypt founded that, the selectivity order Fe3+ > Al3+ > Mn2+ >Zn2+> Pb2+.
