建立了鲁米诺-过氧化氢化学发光流动分析法测定海水中痕量锰的方法。该方法操作简单，除铁离子外，几乎所有金属离子均不干扰化学发光检测。通过使样品溶液通过8-羟基喹啉固定化螯合树脂柱，彻底除去铁物种。检测下限和上限分别为0.029nM和4μM。相对标准偏差为0.58%，在10 nM的Mn（II）。该方法允许选择性和灵敏度测定亚纳米水平的锰在海水样品中具有足够的精度。
A flow through analytical method has been developed for the determination of trace amounts of manganese in sea water using luminol–hydrogen peroxide chemiluminescence (CL) detection. The method was very simple and almost all the metal ions did not interfere with the CL detection except for iron species. The iron species were thoroughly removed by passing the sample solutions through a 8-quinolinol immobilized chelating resin column. The lower and upper limits of detection were 0.029nM and 4μM, respectively. The relative standard deviation was 0.58% at 10nM of Mn(II). The method permitted the selective and sensitive determination of sub-nM levels of Mn in sea water sample with sufficient precision.
