Application
- Optimisation of sample pre-treatment in the HG-AAS selenium analysis.: Explores methods to improve sample preparation using amidosulfuric acid in hydride generation atomic absorption spectroscopy, which is crucial for detecting selenium in environmental samples (Schloske et al., 2002).
- [Preparation and use of amidosulfuric-acid-containing tablets for titration purposes].: Describes the formulation and application of amidosulfuric acid tablets designed for titration, simplifying quantitative analyses in chemical education and research (Subert and Chalabala, 1973).
