Development of a Rotary Disc Voltammetric Sensor for Semi-continuous On-site Measurement of Heavy Metals

摘要

This study characterized a new type of RDV sensor has been detected of trace levels of Pb(II), Cd(II) in non-deoxygenating solutions. Specifically determination of heavy metals was made by SWASV. In addition, the RDV sensor showed a correlation coefficient of 0.998 for the Pb(II) and 0.999 for Cd(II) at 180s deposition time. It is predictable that this advanced monitoring technique is more helpful for environmental engineers to create effective heavy metals treatment systems.
