A sensitive and selective method for the determination of lead(ll) with N-pchlorophenylcinnamohydroxamicrnacid modified carbon paste electrode has beenrndeveloped. The iead(ll) is accumulated on the electrode surface by the formation of therncomplex in an open-circuit/ and the resulting surface is characterized by mediumrnexchange, potential reduction, and differential pulse anodic stripping voltammetry. Thernelectrochemical response was evaluated with respect to carbon paste composition,pHrnand concentration of accumulating and stripping solutions, preconcentration time,rnlead(ll) concentration, and other variables. Two linear ranges were obtained in thernconcentration ranges 1.00 x 10-6 - 2.40 x 10'5MPb(ll) with 2 min preconcentration timernand 2.00 x 10-8 - 1.00 x 10â€™6MPb(ll) with 6 min preconcentration time. The detectionrnlimit was found to be 1.00 x 10 s M with 6 min preconcentration time. For sixrnpreconcentration/medium exchange/voltammetric determination/renewal cycles, therndifferential pulse voltammetric response was reproduced with 5.3% and 4.9% relativernstandard deviations at 4.00 x 10*6Mand 8.00 x 104MPb(ll), respectively. Rapid andrnconvenient renewal allows the use of a single modified electrode surface in multiplernanalytical determinations over several weeks. Many coexisting metal ions had little orrnno effect on the determination of lead(ll). The developed method was applied to leadrndetermination in potable water
