Influence of boron doped diamond electrodes properties on the elimination of selected pharmaceuticals from wastewater

Popis výsledku v původním jazyce

Electrochemical oxidation of four pharmaceuticals from different therapeutic classes: carbamazepine, diclofenac, trimethoprim and venlafaxine on boron doped diamond electrodes in wastewater was investigated. The influence of basic deposition parameters of boron doped diamond layer (CH4/H-2 ratio and boron-to-carbon concentration (CB-C) in gas phase) as well as surface morphology of the Si substrate was studied. The combination of liquid chromatography-tandem mass spectrometry was used for evaluation of removal efficiency of target compounds. Based on quantitative analyzes, no clear influence of CH4/H-2 ratio (in range from 2% to 2.83%; constant CB-C 10,000 ppm) on the removal efficiency was found. An increase CB-C from 10,000 ppm to 15,000 ppm caused a decrease of removal efficiency. The use of boron doped diamond layer grown on structured Si substrate led to a significant increase in removal efficiency (almost 100%). Finally, degradation and transformation products of selected pharmaceuticals were identified by liquid chromatography with high resolution mass spectrometry. Most of the identified oxidation by-products formed during electrochemical oxidation were chlorinated.
