【摘要】 研究了 PAIV萃淋树脂色层柱在钕浓度 0 .414× 10 - 6 、2 5～ 30 m L溶液中对钕的吸附 ,选择含有草酸或EDTA的稀硝酸溶液进行淋洗 ,可以使钕富集近 4倍 ,用分光光度法测定淋洗液钕含量 ,回收率为 10 3.1%更多还原

【Abstract】 The adsorption of Nd on PAIV levextrel chromatographic column for its volume 25~30mL and concentration 0.414ppm was investigated.The concentration of Nd can be concentrated about 4 times with suitable nitric acid elution which includes some H 2C 2O 4 or EDTA.Nd is measured by spectrophotometric method and its recovery is 103.1%.更多还原
