摘要

探讨了钕与丙氨酸、咪唑形成荧光配合物的各个因素

确定了用液体荧光法测定钕元素的最佳条件。实验表明

钕与丙氨酸和咪唑形成荧光配位化合物的最佳条件为:丙氨酸和咪唑的量的比为5:1

pH=5.0;钕配位化合物荧光强度的最佳测量条件为:激发波长220nm

发射波长350nm

激发狭缝带宽5nm

发射狭缝带宽10nm;溶液钕含量的最低测量下限为0.5g/mL。应用该方法测定了氧化钕和陶瓷产品中的钕含量。

Abstract

Fluorimetric liquid method was used for the analysis of neodymium resulting from the formation of fluorescent complex among neodymium

alanine and imidazole

and the effects of various factors were discussed. The optimum reaction conditions of the complex are

(alanine):

( imidazole)= 5:1

pH=5.The optimum excitation light wavelength is 220 nm

the emission light wavelength 350 nm

the excitation slit 5 nm

and the emission slit 10 nm. On the basis of these conditions

neodymium(Ⅲ) can be determinated at a low detection limit of 0.5 g/mL. Further

neodymium(Ⅲ) concentrations of neodymium oxide and neodymium ceramic product were determined using this method.
