Application of potentiometric stripping analysis with constant inverse current in the analytic step for determining lead in glassware
The trace amounts of lead in extraction glassware products were determined by potentiometric stripping analysis with constant inverse current in the analytic step (PSA-iR), an electrochemical technique of high sensitivity and selectivity. This paper deals with an investigation which was directed to...

The trace amounts of lead in extraction glassware products were determined by potentiometric stripping analysis with constant inverse current in the analytic step (PSA-iR), an electrochemical technique of high sensitivity and selectivity. This paper deals with an investigation which was directed to the effect of a great number of factors on the results of PSA-iR, of lead in glassware, such as the mercury time electrodeposition, the electrolysis potential, the solution stirring rate and the constant inverse current. Linearity of the lead analytical signal was achieved within the range of mass concentrations from 2.5 μg/dm3 to 4.5 μg/dm3.Adetection limit of 0.64 μg/dm3 was obtained, with a reproducibility of 4.14 % expressed as the coefficient of variation. The analyses were carried out using a computerized stripping analyzer of domestic design and manufacture (Faculty of Technology, Novi Sad and "Elektrouniverzal", Leskovac).
