Summary : The objective is the determination of the conditions operating optimal to determine the concentration of the cadmium and the lead dissolved in the human blood. An electroanalytical method has been developed for the determination of lead and cadmium in whole blood by differential pulse anodic stripping voltammetry (DPASV) on a hanging mercury drop electrode (HMDE). The best conditions were found to be electrolyte support perchloric acid 0.02 M, the accumulation potential is -900 mV, and the accumulation time is 320 s. The obtained limits of detection are equal to 0.46 and 0.08 ng/mL
respectively for the lead and the cadmium. The developed method was validated by the analysis of reference materials certified by total blood. |
