摘要
研究了在Tfiton X-100存在下,某些稀土元素与1-苯基-3-甲基-4-苯甲酰基吡唑酮-5形成配合物的4f电子跃迁的光谱性质。拟定了三阶导数光谱直接测定混合稀土中Nd和Er的方法,用于合成样及稀土矿样分析,结果满意。
The spectral characteristics of 4f electron transitions for some rare earth complexes formed with l-phenyl-3-methyl-4-benzoylpyrazolone-5 in the presence of triton X-100 are studied. A phtometric method is suggested to determine directly Nd and Er in mixed rare earths. It has been used to determine Nd and Er in two synthetic samples and a rare earth material, satisfactory results are obtained.
