Antimony Powder-Modified Carbon Paste Electrodes for Electrochemical Stripping Determination of Trace Heavy Metals
Original language description
A new type of the antimony electrode based on a carbon paste bulk-modified with antimony powder (Sb-CPE) is presented for the determination of cadmium(II) and lead(II) ions at the ug L-1 concentration level, when using SWASV or stripping chronopotentiometric protocol. Key-operational parameters, including the amount of antimony powder in the carbon paste mixture, effect of the deposition potential and deposition time, were optimized and electroanalytical performance of the Sb-CPE in nondeaerated solution of 0.01 M hydrochloric acid (pH 2) was compared with related bismuth powder-modified carbon paste electrode (Bi-CPE) and with in situ prepared antimony film carbon paste electrode (SbF-CPE). Favorable limits of detection were achieved; namely: 1.4 ug L?1 for Cd(II) and 0.9 ug L?1 for Pb(II). The applicability of the new electrode was demonstrated on the analysis of tap water. The Sb-CPE was preliminary tested also under chronopotentiometric stripping mode in deoxygenated solutions.
