Abstract
Normal urine samples of healthy adult individuals of nearly same age have been successfully analysed for lead determination by linear scan anodic stripping voltammetry. Analyses of undigested as well as digested samples have been performed for lead both by a modified sample addition as well as by standard addition methods. The results obtained in both cases are compared with each other. Good agreement is obtained between the two methods. The results obtained by the two methods are also compared with the results given in the literature. The detection limit is 0.4 ppb of the lead for a 5 minutes duration of electrolysis.
