Comparison of lab-made boron-doped diamond electrodes in electroanalysis of linuron and mesalazine

Abstract

In this study, electrochemical properties of lab-made sensors based on boron-doped diamond (BDD) prepared by hot filaments chemical vapor deposition under different conditions and its application options for determination of substituted urea herbicide linuron and drug mesalazine have been studied. The B/C ratio in the gas phase was varied in the range from 1 000 to 20 000 ppm and the content of CH4 in H2 mixture was 1 %. Parameters of DPV and SWV were optimized on commercial BDDE. These methods were applied for analysis of both analytes using all tested BDDEs, and the calculated statistical parameters were compared.
