摘要
本文用流动注射荧光分析法研究了三价铈在无机稀酸中的荧光性质.利用此性质建立了测定微量铈(Ⅲ)的方法.铈的线性范围0～100pbb.本法简便快速,灵敏度高,重现性好,己成功地应用于合成样品中铈(Ⅲ)的测定、
The fluorescence property of Ce(Ⅲ) in hydrochloric or sulphuric acids is studied with flow injection fluorescence analysis. A method for the determination of trace Ce(Ⅲ) has been established. The fluorescence was measured at 354nm (excitation at 258nm). The linear range is 0-100 ppb and the detection limit is 0.1ppb. The sampling rate is 180/h. The results for the determination of Ce(Ⅲ) in synthetic sample are satisfactory.
