Abstract
Reductive potentiometric stripping analysis (RPSA), with potassium fer rocyanide as the reducing agent on a glassy carbon electrode, is appli ed for the determination of lead over the range 2 x 10(-8)-5 x 10(-6) M. The relative standard deviation of 2 x 10(-6) M lead for ten consec utive measurements is 2.5%. This technique has been used to determine the minute amount of lead in a human hair sample solution.
