Abstract

The present invention relates to a screen-printed electrode (1) for detecting a pollutant in a water sample, comprising: a substrate (2); a plurality of conductive tracks (3); an electrochemical cell (4), further comprising a working electrode (5), a pseudo-reference electrode (6) and an auxiliary electrode (7); and an insulating layer (8). Advantageously, said electrode comprises a filtering element (9) arranged in contact with the electrochemical cell (4) and configured to filter the water sample received by the electrochemical cell (4). Optionally, said filtering element (9) may be impregnated with an electrolyte, preferably sodium hydroxide, to precondition the water sample, favoring the electrochemical degradation of the pollutant present thereof. Therefore, the screen-printed electrode of the invention saves time in pre-processing samples for water pollution analysis while avoiding any possible contamination thereof by user manipulation.
