Abstract: | Abstract A novel fast system based on the integrated film electrodes was created. The resulting system was successfully applied in the detection of blood lead, by means of differential pulse anodic stripping voltammetry in tiny amount of volume, ~50 µl, codeposited with Hg without removal of oxygen. Under the optimum conditions, the peak current was linear to Pb2+ concentration from 1.2 to 70 µg/dl, and detection limit was 1.2 µg/dl. Blood lead was detected with calibration curve, y=9.726E? 8+9.959E?8 x (R=0.998). Compared with other methods reported, this method was more rapid, low‐cost, and could meet the requirement of real‐time analysis. |
