Studies on Fine Absorption Spectrum of Neodymium Ion in Chloric Acid and Its Analytical Application

对钕的精细吸收光谱进行了系统的研究 ,考察了钕的浓度、基线峰和参比液对钕的精细谱图的影响 ,提出了利用钕的精细吸收光谱来测定低钕离子浓度的方法 .实验结果表明 ,利用钕的吸收光谱可直接准确测定 0 .0 35～ 35mg/m L钕的离子浓度 .该方法简单、快速 .

In this paper,the fine absorption spectra of Neodymium has been studied.A fine spectrophotometric method for the determination of Nd has been developed.The effect of the concentration of Nd,basic line peak and blank solution has been discussed.The result indicates that when the basic peak was chosen,the 0.035-35mg Nd/mL can be well detected directly by this method,and it is simple and rapid.Furthermore,satisfactory results can be obtained for samples.
