Optimization of experimental setup for chemiluminescent determination of cobalt ions

The presented thesis deals with finding the optimal experimental setup for the chemiluminescent determination of cobalt ions by the technique of flow injection analysis (FIA) and sequential injection analysis (SIA) and comparing the achieved results of the determination. The determination is based on a chemiluminescent reaction, essence of which is oxidation of luminol with hydrogen peroxide in an alkaline solution in a flow system in the presence of cobalt ions, which acts as a catalyst of the reaction. In the experimental part of the work, a suitable setup for the detection of chemiluminescent light emission was found, followed by a suitable setup of the FIA and SIA systems for the determination of cobalt ions. For the detection of radiation, a glass spiral tube was selected, which was the most suitable for chemiluminescent measurement, compared to other experiments performed with different. In the next part of the work, optimal conditions for cobalt ions determination were experimentally found. As for the FIA technique, the volume flow rate of hydrogen peroxide, luminol and cobalt ions solutions was optimized. Furthermore, the concentration of the hydrogen peroxide solution and luminol. Last but not least, the dosing volume of the cobalt ions solution and the pH of the luminol solution were..
