Abstract
|

|
|
The Determination of trace of selenium by Cathodic stripping voltammetry has been studied using hanging mercury drop electrode. The effect of several supporting electrolytes containing of iodide and collection potential, collection time, pH on the stripping;voltarnmetric peak of selenium was tested. The sensitivity of selenium in presence of 2.5 x10-5M iodide increased to 5.0 x 10-8 mole/L. The addition of iodide allows the selective meastu´:ement of selenium in the presence of lead,
