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

对铈的精细吸收光谱进行了系统的研究 ,重点讨论了铈的精细吸收光谱的基线选择问题 ,提出了利用铈的精细吸收光谱来测定低铈离子浓度的方法 .实验结果表明 ,利用铈的精细吸收光谱可直接准确测定 0 .2 0～2 2 mg/m L铈的离子浓度 .该方法简单、快速 .在实际样品分析中取得满意的结果 .

In this paper,the fine absorption spectra of Cerium has been studied.A fine spectrophometric method for the determination of Ce has been developed. The result indicates that when the basic line was chosen,the 0.20-22 mg Ce/mL can be well detected directly by this method,and it is simple and rapid.Furthermore,satisfactory results can be obtained for samples.
