Abstract
This paper presents a new technology using Bismuth-film to determinate lead instead of mercury film. It is proved in the experiment that, in the optimum measuring situation (when the pH is 4, deposition time is 150s, and the deposition potential is 0.8.), the lead concentration and stripping peak current shows a good linear relationship in the measuring range of 10 to 110ug/L, which is I=0.1002C+0.0539. The experimental analysis shows that the concentration of lead in tea samples is 1.667μg / g, and the recovery rate is 91.2% ~ 101.8%. It is proved that the method of bismuth film electrode is used to measure lead with advantages of convenience, speediness, sensitivity and accuracy, etc.
