The effective utilization of industrially waste cinder for electroanalytical applications by trapping the hexacyanometallate (HCF) units from Fe3+, Ni2+, Co3+, etc into the interlayer galleries of cinder has been reported. Prussian blue (PB) is an Fe(III)-HCF with mixed valence and zeolite type properties. In the present investigation, the intercalation property of Tl+ with PB/cinder paste electrode (designated as PBCPE) has been utilized for the analytical purpose. Basic cyclic voltammetric experiments with Tl+ in 0.1 M KNO3 results in a continuous insertion of Tl+ ions inside the PB gallery with the ejection of K+ ions. The insertion rate of Tl+ ions in the PBCPE was much faster as compared to that in traditional PB-modified electrodes. The PBCPE has also been utilized for sensitive determination of Tl+ ions in real samples.
