摘要: Inductively coupled plasma atomic emission spectrometry (ICP-AES) interfaced with high-performance liquid chromatography (HPLC) has been applied to the determination of rare earth elements. ICP-AES was used as an element-selective detector for HPLC. The separation elements HPLC helped avoid erroneous analytical results due spectral interferences. Fifteen (Y and 14 lanthanides) were determined selectively HPLC/ICP-AES system using a concentration gradient method. detection limits present about 0.001-0.3 ..mu..g/mL 100-..mu..L sample injection. calibration curves obtained by peak height measurements showed linear relationships in range below 500 all A USGS rock standard sample, ores, high-purity lanthanide reagents (>99.9%) successfully analyzed without
