Resumen:
|
Extraction using 0.28 M nitric acid at 95 °C for 90 min recovers not only arsenic quantitatively from rice grains independent of types but also preserves arsenic speciation completely. It is simple, economic, effective and reliable and is especially suitable for routine analysis of large amounts of samples.
