Resumen

A simple differential pulse voltammetric method based on chitosan modified glassy carbon was used to pre-concentrate copper ions in the chitosan film. After, this electrode was employed for the quantitative determination of cysteine. The modified electrode exhibits a clear improvement of the current response. The method allowed quantifying the analyte in the range in buffer solution and a limit of detection range from 1.0×10-6 to 1.4×10-6 M was achieved. This value seems quite higher than those previously published by other authors. The results are described and discussed in the light of the existing literature.
