Porovnání borem dopovaných diamantových elektrod s různým obsahem boru při stanovení herbicidu linuronu a léčiva mesalazinu

Abstrakt

In this work, the application possibilities of the boron-doped diamond (BDD) electrodes with various boron content for the determination of linuron (a substituted-urea herbicide) and mesalazine (a drug) have been studied. The boron/carbon ratio in the gas phase during BDD film deposition varied from 1000 to 20 000 ppm and the content of CH₄ in H₂ mixture was 1 %. Voltammetric methods based on differential pulse voltammetry (DPV) and square wave voltammetry (SWV) developed with commercial BDD electrode were applied for analysis of both analytes using tested BDD electrodes with different boron content, and the obtained statistical parameters were compared.
