Abstract:
Microwave is the most reliable sample digestion method. However, it requires expensive microwave digester automation and has relatively low productivity. In this study, three non-automated digestion methods, i.e. wet acid digestion using nitric acid (HNO₃) and hydrogen peroxide (H2O₂), wet acid digestion using HNO₃, and dry washing, are compared in order to determine the best approach.
