激光等离子体光谱法测定水溶液中钠

Determination of Na in Solution by Laser-Induced Plasma Spectroscopy

建立了一套激光等离子体光谱测量装置 ,测定溶液中不同浓度 Na的 5 89.0 nm谱线强度 ,得到浓度 -强度校准曲线。浓度 0 .1 %时的最大相对误差为 9.1 3%。对氯化钠生理盐水进行了测定 ,结果吻合得很好。

Na in solution was determined by laser-induced plasma spectroscopy with an experiment equipment at spectral line of Na 589.0nm.The maximum relative error of 9.13% occurs at concentration of 0.1%.NaCl in physiological brine was measured with satisfactory results.
