Professional analysis and design kits for a variety of water conditions? waterproof design, durable anodic stripping voltammetry anodic stripping voltammetry invented in the 19th twenties century, and in 1969 its inventor Jaroslav Heyrovsky won the Nobel Prize in Chemistry. Anodic stripping voltammetry to restore electrical potential is applied to the working electrode, when the electrode potential exceeds precipitation potential of certain ions in solution the metal ions are reduced to metal plating on the working electrode surface; when sufficient metal plating on the working electrode surface to the working electrode potential constant rate of increase, the metal plating on the electrode will produce dissolution (oxidation). Each metal has a specific dissolution (oxidation) reaction of a voltage, according to the dissolution (oxidation) generates potential value to identify the type of metal, and generates dissolution (oxidation) potential differences between different kinds of metals, simultaneous measurement of a variety of metals, to measure the current and recording the corresponding potential to calculate the concentration of metal ions. Applications for the determination of heavy metals in drinking water, surface water, beverage, environmental water, sea water, industrial waste water and other widely used to examine soil, food, solid matter content of heavy metals
