Catalytic-oxidation of Janus green in the presence of AgNPs: Application to the determination of iodate

Catalytic-oxidation of Janus green was made in the presence of AgNPs. The reaction was monitored spectrophotometrically at 610 nm. The system was optimized for the trace analysis of iodate. The method is featured with good accuracy and reproducibility for iodate monitoring in real samples without any pre-concentration and separation step.
