摘要：

Praseodymium was determined by reaction with 5,7-dichloroquinolin-8-ol and Rhodamine 6G in a weakly alkaline medium. The flotation of the ion association complex was carried out with hexane, followed by dissolution in acetone for subsequent spectrophotometric determination. The molar absorptivity was 1.83 x 10(5) 1 mol - 1 cm - 1 at 530 nm. Beer's law was obeyed in the range 8-240 mug l - 1 praseodymium. Praseodymium in aluminium metal and aluminium salts was determined by the proposed method in conjunction with an ion-exchange separation using Dowex 50W-X8 cation-exchange resin.
