摘要: We report a disposable barrel plating nickel electrode (Ni-BPE) coupled with a specifically designed electrochemical cell for use in flow injection analysis for the determination of trivalent chromium (Cr-III). The response of the activated Ni-BPE was found very sensitive under alkaline condition with a systematic increase in current signal upon successive addition of Cr-III. Under optimized conditions, the calibration curve showed a linear range up to 1 mM with a detection limit (S/N= 3) of 0.30 mu M. Continuous hydrodynamic flow of 0.1 M NaOH at regular Cr-III injections verify the reproducibility of the present system. The proposed method was successfully used to detect the amount of Cr-III in environmental water to show its potential use in real applications. (c) 2007 Elsevier B.V. All rights reserved.
