Abstract:The contents of K&Na in chemical reagent of (NH 4) 2Cr 2O 7 have been determined by means of Atomic Absorption Spectrometry.The experimental results demonstrate that this method is high accurate, simple and rapid. The recovery of K?Na are over 95.2% and 92.0%, and the RSD of K?Na are 4% and 3%, respectively.
Key words:atomic absorption spectrometry; (NH 4) 2Cr 2O 7; potassium; sodium
