离子交换树脂光度法可直接将被测化学组分同时浓集和选择性吸附于树脂上进行光度测定 ,不需预浓缩和分离 ,故具有比溶液光度法更高的灵敏度和选择性 ,同时简化了分析手段 ,可检测样品液中痕量金属离子的含量。研究了 TBA—稀土络合物定量富集在强碱性的阴离子交换树脂上的最佳实验条件 ,并直接测定了合金样中的稀土总量
Ion exchange resin spectrophotometry can be directly measured chemical components concentrated and selectively adsorbed on the resin for photometry, without preconcentration and separation, it has a higher sensitivity and selectivity than solution photometry, while simplifying The analysis means, can detect the content of trace metal ions in the sample solution. The optimum experimental conditions for the quantitative enrichment of TBA-rare earth complexes on strongly basic anion exchange resins were studied and the total amount of rare earths
