Abstract:
In this work we report a simple method for the synthesis of uranyl ion imprinted and non
imprinted polyaniline (IPAN and NIPAN) and a copoly mer of 8-hydroxyquinoline
functionalized aniline (ANHQ) and aniline (IFPAN and NIFPAN) using potassium dichromate
and ammonium persulphate as the initiators. The structural characterization of the synthesized
materials were done by FTIR and UV-Visible spectroscopy, morphology by SEM, thermal
properties by TG and electrochemical properties by cyclic voltammetry. Application of the
synthesized materials in removal of uranyl ion was studied using solid phase extraction (SPE).
Various parameters were optimized to get quantitative removal from aqueous sample buffered
to neutral pH using ammonium acetate. Selectivity and reusability studies were carried out to
demonstrate the possible application in real sampleanalysis
