Development of methods for the voltammetric determination of chloramphenicol and dinitramin at amalgam electrodes

(referee)
The first part of this diploma thesis deals with the determination of chloramphenicol (CLF) on the retractable-pen-based renewable silver amalgam film electrode (RAE) by differential pulse voltammetry (DPV). Calibration dependencies in the concentration range of 10-100 µmol dm−3 and 1-10 µmol dm−3 were obtained. Repeated RAE surface restoration when determining CLF does not contribute to the repeatability of the signal. The determination limit was 2,2 µmol dm−3 . In the second part of the work, the conditions for the determination of dinitramine (DN) were examined on the meniscus-modified silver solid amalgam electrode by DPV technique. The Britton-Robinson buffer pH 5 was chosen as the optimal medium. In this electrolyte, the impact of regeneration potentials on DN signal stability was monitored. Regeneration pulses or methanol rinses did not contribute to the stability of the signal. There is a strong passivation on the electrode, so this type of electrode is not suitable for determination of this analyte. The possible solution is to use RAE, in which mechanical surface restoration is an effective way of solving the passivation on the electrode surface. In the third part of the work, dinitramine was studied at the RAE. The best repeatability of the measurements was achieved by activation of the...

Development of method for voltammetric determination of chloramphenicol at retractable-pen-based renewable silver amalgam film electrode

(referee)
This diploma thesis is focused on the determination of chloramphenicol (CLF) by differential pulse voltammetry (DPV) on retractable-pen-based renewable silver amalgam film electrode (RAE). For the determination of chloramphenicol the optimum conditions were found. Under these conditions concentration dependences were measured and then limits of quantification were calculated. The effect of pH of Britton- Robinson buffer was tested and the stability of the signal with repeated measurements was monitored. For determination of CLF by DPV BR buffer pH 7 was chosen as an optimum background electrolyte. Under these conditions linear dependences were obtained in the concentration range of 1·10−5 −1·10−4 mol·dm−3 and 1·10−4 −8·10−4 mol·dm−3 . The limit of determination for CLF by DPV at 1,4·10−5 mol·dm−3 was found.
