中文摘要	a tantalum electrode is reported as an alternative electrode for electrochemical stripping analysis for the first time. several key operational parameters that influenced the electroanalytical signals were optimized, such as ph of the electrolyte, deposition potential and deposition time. the tantalum electrode yields well-defined and sharp stripping signals for trace cadmium analysis when combined with differential pulse anodic stripping voltammetry. under the optimized condition the electrode shows good linear behavior in the examined concentration in the range of 20-200 mu g l-1 for cadmium, with a detection limit (3 sigma) of 0.57 mu g l-1 followed a 5-min deposition step under -1.3 v. it also shows good reproducibility with a relative standard deviation of 2.56% for ten consecutive measurements. the sensor was also employed for real sample determination and exhibited excellent performance compared with the result of inductively coupled plasma-mass spectrometry.
