Synthesis, characterization and analytical applications of sodium dodecyl sulphate cerium (IV) phosphate: A new Pb (II) selective, surfactant-based intercalated fibrous ion exchanger

Sodium dodecyl sulphate-based cerium (IV) phosphate (SDS-CeP), a new Pb (II) selective intercalated fibrous ion exchanger, has been synthesized. It has been characterized on the basis of X-ray diffraction analysis, IR, thermo-gravimetric and differential thermal analysis, scanning electron microscopy (SEM) and ion exchange studies. The adsorption studies have also been carried out for some alkaline earths and heavy metal ions in different acidic media, showing a marked selectivity towards Pb (II), a toxic metal ion. Hence, its analytical utility has been established by achieving some binary separations on its column. The prepared material has shown good ion exchange capacity (2.92 meq/dry g basis), thermal stability and adsorption behaviour. The ion exchanger may play an explicit role in environmental studies.
