Abstract
The aim of this study was the development and validation of a new inductively coupled plasma optical emission spectrometry (ICP-EOS) method for determination of Cr(VI) from vegetable samples. The new method was completely validated through verification of performance parameters (linearity, inter-day and intra-day precision, limit of detection - LOD and limit of quantification - LOQ). The vegetable samples, mint and basil, were contaminated with a known amount of K2Cr2O7. Cr(VI) was extracted from the vegetable samples by ultrasound assisted extraction technique, using 0.1 M Na2CO3 as extraction medium. The ICP-EOS method proved to be very sensitive, allowing to determine up to 3.0 µg/g Cr(VI) in vegetable matrices, value which was established as the method LOQ.
