| Abstract;A simple spectrophotometric flow injection (FI) procedure for the determination of Cr(III) using ethylenediaminetetraacetic acid (EDTA) was developed. An FI system with a column packed with Amberlite IR-120(H) was employed for sample pretreatment. This leads to the possibility of a single standard calibration. A linear calibration in a range of 10-27 .MU.g Cr(III) was obtained with a detection limit of 1 .MU.g Cr(III) and RSD of 2% (18 .MU.g Cr(III), n = 12). The proposed procedure was applied for determination of Cr(III) in leachate and dietary supplement samples. The results agreed with those obtained by the standard methods. (author abst.) |
