摘要
探讨了用DX-300型离子色谱仪测定在其它高浓度阴离子存在下微量NO_3^-的方法,采用电导检测器与紫外检测器联用技术,既可克服基体高背景对微量NO_3^-测定的干扰,又可同时测定共存的其它阴离子,如Cl^-、SO_4^(2-)等.方法用于测定镀镍液及其原料硫酸镍中NO_3^-的分析,得到了满意结果.
A method for the determination of micro-amounts of NO3~ ion in the presence of large amounts of other anions by DX-300 model lon-chromatograph using conductometric and UV-spectrometric detectors is reported in this paper. Several other anions, e. g. , C1~、SO4^(2-) , can be determined simultane-ously. The proposed method has been applied to the determination of NO3~ ion in Ni-plating solution and nickel sulfate with satisfactory results.
