The aim of this dissertation thesis "Development of electrochemical detector for heavy metal monitoring" was to create sensible sensors for the determination of heavy metals in the aquatic ecosystem and which would be usable for real applications, determination of the content of various metals in waste industrial waters. For the simultaneous determination of Zn(II), Cd(II), Pb(II) and Cu(II), a carbon paste electrode modified with chromium oxide was developed, based on this modification were produced the screen printed electrodes for the simultaneous determination of said metals with good limit of detection. For the usability of printed sensors in situ, a new electrochemical cell design was designed. This proposed cell also facilitates dosing of samples and buffer necessary for electrochemical analysis. Further, for determination of the total chromium content in aqueous solutions, was introduced a new method using a silver film on a glassy carbon electrode. Finally, various methods for waste water treatment from heavy metals have been tested.
