A linear response was observed from 1 to 50 μg L−1. The proposed method is selective, and presents good reproducibility (7.4%) and repeatability (7.0%). The sample throughputwas 21 h−1 and the detection limit was 0.60 μg L−1. This methodology regarding the AOAC method is simple, low cost, low consumption of reagents and provides results in considerably less time. Moreover, ICP-AES technique requires high cost instrumentation and employs higher amounts of reagent and sample than the proposed electroanalytical method.
