| Opis: | The optimum reaction parameters for the interaction of hexavalent chromium [Cr(VI)] with diphenylcarbazide in microfluidic
chips (μFIA) with thermal-lens microscopic detection were selected. The characteristic feature of the applied
flow scheme is the injection of the reagent into the stream containing the test metal, which enables in-field and
real-time monitoring of Cr(VI) simply by flowing the sample continuously through the microchip. The limit of detection
of Cr(VI) under the selected conditions (signal generating wavelength, 514.5 nm; excitation power, 100 mW; detection
position, 10 cm downstream from the mixing zone of the microchip; flow rate 10 μL min–1; injection volume,
1.4 μL) is 15 ng mL–1 (2.9 × 10–7 mol L–1). The linear range is 40 ng mL–1 – 10 μg mL–1 with a relative standard deviation
no higher than 10% in the concentration range 0.1–1 μg mL–1. The online monitoring by this scheme provides the
possibility of up to 360 analyses per hour. |
