| ABSTRACT |
| Determination of soil Se by anodic stripping voltammetry (ASV) with aurum thin-film electrode (ATFE) overcomes the interference of gold peak with selenium peak, and thus has a higher sensitivity with the minimum detectable wncentration being 0.017 pg/mL, the standard deviation of the measured results less than 0.012 μg/g, the coefficient of variation lower than 10%, and the recovery rate between 86% to 103%. Besides the measurement conditions, the digestion of soil sample was also studied in detail. |
