Synthesis and characterization of lead(II) selective sodium dodecyl benzene sulphonate-cerium(IV) phosphate ion exchanger

The surfactant based sodium dodecyl benzene sulphonate-cerium(IV) phosphate (SDBS-CeP) fibrous ion exchanger has been synthesized and was characterized by using various physico-chemical methods. The X-ray, TGA/DTA, SEM and elemental analysis were used to characterize the ion exchanger. The ion exchange property was studied by carrying out the ion exchange capacity, elution, concentration and thermal behavior. Adsorption studies on the synthesized material have also been performed for heavy metal ions in alkalis and acidic media. The material has been found to be selective for Pb2+ and therefore, the binary separations of Pb2+ from other metal ions have been performed on its column and observed to be quite effective in the presence of alkali, alkaline earth and transition metals.
