The analytical utility of the electrochemical PADs is demonstrated through electrochemical determination of Pb(II) and Cd(II) by anodic stripping voltammetry. Our products measure parameters such as pH, conductivity, temperature and moisture for optimum plant growth. The ePADs were applied to the simultaneous determination of Pb(II) and Cd(II) by anodic stripping voltammetry using bismuth-coated working electrodes and the limits of detection were lower than the legislative limits. Why Choose Bluelab Conductivity PPM Pen? Heavy metals are toxic species that can accumulate in living organisms via the consumption of food and water, breathing, and absorption through the skin [, The current requirements for on-site analysis had a great impact on the way towards the development of miniaturized, low-cost, integrated, and disposable analytical devices and sensors [, Several paper-based devices have been reported for heavy metal and metalloid determination by stripping analysis.
