摘要:Based on the adsorption of Fe(EDTA)(-) on a chitosan-coated glassy carbon electrode, a second-derivative square-wave voltammetry for the determination of the EDTA species in water samples was investigated. The measuring range of EDTA was from 6.0 x 10(-7) to 5.0 x 10(-5) mol/L with a correlation coefficient of 0.998 and a detection limit of 2.8 x 10(-7) mol/L. The relative standard deviation was less than 6.2% (n = 5) and the recovery was in the range of 98 - 105% for the determination of practical samples. The result was consistent with that from the HPLC method.
