Summary
For determination of trace Se we used high-pressure wet digester to pretreat the specimens obtained from the human body. This method is very effective in preventing loss of Se by volatilization which often occurs in the sample pretreatment. We studied the method of using anodic stripping voltammetry at gold-disc electrode to measure the trace Se present in the human body and found it to be the optimal procedure. The detection limitation was about 2x10−8 g/L, the recovery rate of Se about 96.6±6,7 %\((\bar x \pm s)\), and the coefficient of variation CV = 7.0%.
