Anodic Stripping Voltammetric Detection Of Zn(Ii), Cd(Ii) And Pb(Ii) Of Coal Gangue At Bismuth Film Glassy Carbon Electrodes

For coal gangue it is very important to detect the heavy metals of the products in view of environment risk control, because the heavy metals in coal gangue can cause multiple significant toxic effects. Most of the techniques now available are more suitable for laboratory conditions only and usually cost much testing time. In this work, we develop a new rapid detecting method of Zn(II), Cd(II) and Pb(II) in coal gangue based on anodic stripping voltammetry. Through a large number of experiments, operational parameters have been optimized. This work provides a quick and convenient detection method for heavy metals in coal gangue.
