【Abstract】 Compound sodium chloride injection was determined directly by atomic absorption spectrometry(AAS).The interference from coexistent elements(K+.Na+)was eliminated by and accurate.The satisfactory recoveries[101. 2% (Na+), 100. 4% (K+) and 100.2% (ca++ )] were obstained with RSD of 1.6%, 1.5% and 1.2%, respectively.更多还原
