A Potentiometric Sensing System for Lead |
|
| Abstract: | Abstract A pontentiometric flow system based on a sparingly soluble mixture of lead laurate and lauric acid as the responsive element and a glass electrode as the primary sensor is reported. The response of the system to copper, cadmium, zinc and aluminium is also presented.Although the system is relatively unselective, it has the advantage over commercial (Ag2S/PbS-based) lead ion-selective electrodes of reversibility of response to copper and cadmium. |
