本文提出了一种分离富集测定痕量Cu（Ⅱ）、Co（Ⅱ）、Cd（Ⅱ）、Fe（Ⅲ）和Mn（Ⅱ）的新方法。金属离子与1-亚硝基-2-萘酚在pH 9络合。在Diaion HP-20树脂上固相萃取后，通过火焰原子吸收光谱法测定金属。考察了基体离子对体系的影响。金属离子的回收率大于95%。的分析物离子（k = 3，N = 21）的检测限变化为0.18微克/升的镉（II）的0.44微克/升的铁（III）。方法用于水系沉积物标准物质（GBW 7309）、铵盐和工业肥料样品中铜、钴、镉、铁和锰的测定。分析物离子在μ g/g水平下测定的相对标准偏差（RSD）为1 - 10%。
A sensitive and simple separation-enrichment technique for the determination of trace amounts of Cu(II), Co(II), Cd(II), Fe(III) and Mn(II) was described. Metal ions were complexed with 1-nitroso-2-naphthol at pH 9. Following solid-phase extraction on Diaion HP-20 resin, metals were determined by flame atomic absorption spectrometry. The effect of the matrix ions were investigated. The recoveries of metal ions were greater than 95%. The detection limits of the analyte ions (k = 3, N = 21) were varying 0.18 mug/l for Cd(II) to 0.44 mug/l for Fe(III). The method was applied to a stream sediment standard reference material (GBW7309), some ammonium salts and industrial fertilizer samples for the determination of copper, cobalt, cadmium, iron and manganese. The relative standard deviations (RSD) of the determinations for analyte ions at mug/g levels varied from 1 to 10%.
