Application
- Large-volume injection electrothermal AAS combined with tungsten-treated pyrolytic graphite furnace: determination of cadmium in tap, snow and river water samples with phosphate modifier.: This research demonstrates the application of phosphate modifiers in enhancing the detection sensitivity of cadmium using electrothermal atomic absorption spectrometry. It provides insights into environmental analysis techniques, particularly in the assessment of water quality (Imai S et al., 2004).
