Automatic electrochemical determination of soil contaminated by heavy metal ions (Cd(II) and Pb(II))

Popis výsledku v původním jazyce

Heavy metal pollution has become one of the most serious environmental problems of today. In this paper, we present low-cost and rapid production of amalgam electrodes, which were used for determination of Cd(II) and Pb(II). Difference pulse voltammetrywas used with following settings: initial potential -1,1 V; end potential -0.2 V; step potential 0.005 V; modulation amplitude 0.025 V; modulation time 0.057 s and interval time 0.2 sec. Optimized parameters were implemented in a robotic analyser. Samples were measured in 24-well plates with a flat bottom. The electrochemical robotic device included three moto-rized units and a positioning system. First unit was rigidly connected to the vertical frame of the electrochemical robot; electrode holder was attached to it and enabled precise vertical (z) positioning of electrode holder (up and down). Microtiter plate was placed on horizon-tally (x/y) positioned board. The limit of detection (LOD) was calculated for the geometric surface of th
