“…The instrumental techniques which have been applied to the cerium determination include X-ray fluorescence [3], inductively coupled plasma-atomic emission spectrometry (ICP-AES) [4,5], graphite furnace-atomic absorption spectrometry (GF-AAS) [5], inductively coupled plasmamass spectrometry (ICP-MS) [6], chemiluminescence [7], fluorimetry [8], ion-selective electrodes [9 -11], spectrophotometry [12,13], and neutron activation analysis (NAA) [14]. Nevertheless, most of these techniques allow only the measurements of the total concentration and require costly and specialized instrumentation, which may not be available in many laboratories.…”

The aim of this work was to obtain an adsorptive stripping voltammetric method for the Ce(III) determination at a carbon paste electrode, chemically modified with N-[(2-hydroxyphenyl)methylidene]-2-furohydrazide (NHMF). The electroanalytical procedure comprised two steps: the Ce(III) chemical accumulation at À 200 mV followed by the electrochemical detection of the Ce(III)/NHMF complex, using anodic stripping voltammetry. The factors, influencing the adsorptive stripping performance, were optimized including the modifier quantity in the paste, the electrolyte concentrations, the solution pH and the accumulation potential or time. The resulting electrode demonstrated a linear response over a wide range of Ce(III) concentration (5.0 -90 nmol dm À3 ). The detection limit was found to be 0.8 nmol dm À3 on the basis of a signal to noise ratio of 3. The precision for six determinations of 10 and 55 nmol dm À3Ce(III) was 5.6% and 2.1% (relative standard deviation), respectively. Application of the procedure to the determination of cerium in phosphate rock and wastewater samples gave good results.

Cathodic Stripping Voltammetric Determination of Cerium Using Indium Tin Oxide (ITO)

et al. 2017

Due to its numerous applications in the field of metallurgy and its role as an alloying element for slowing down the biodegradation of pure magnesium typically known to have very low corrosion resistance, the need to develop simple and inexpensive methods for determination of cerium is important. Ce3+ was determined by cathodic stripping voltammetry (CSV) using Osteryoung square‐wave voltammetry (OSWV) for the stripping step. Indium tin oxide (ITO) was used as the working electrode because of its very good positive potential range with smooth background current. Under optimized conditions, the calibration plot was linear in the concentration range of 100 nM to 700 nM Ce3+. A calculated detection limit of 5.8 nM was found for a 5 min deposition time at ITO based on the 3σ method. Interference from selected metal ions was also examined, and no significant interferences were observed. The good selectivity of this sensor makes it a good candidate for practical applications such as monitoring Ce3+ released into solution during the biodegradation of Mg−Ce alloys being developed for resorbable biomedical implants.
