Trace detection of Ce3+ by adsorption strip voltammetry at a carbon paste electrode modified with ion imprinted polymers

A new carbon paste electrode modified with Ce-IIPs was fabricated for determination of Ce3+. The IIPs in the paste can improve the selectivity and sensitivity. Ce3+ was detected based on its own oxidation peak which is more simple and convenient compared with other undirected method. The novel electrode has been used to detect cerium in catalyst sample solution and satisfactory results are gotten.190
