摘    要:基于衍生试剂与天然水中原生有机质之间对铝的竞争配位,建立了用荧光分光光度法区分天然水中铝形态的方法。以铬蓝黑R和桑色素为分析试剂可以测定无机单核铝,而以8-羟基喹啉为分析试剂则可以测定总单核铝,实验结果与用Driscoll方法所得到的结果基本一致。为有目的地选择分析试剂,在天然水自身pH条件下进行铝形态的直接分析提供了一个新的方法选择。相对来说,荧光分光光度法操作更加简单,条件温和,对原始样品几乎没有扰动,天然水中铝形态分析的结果更符合真实情况。

关 键 词:荧光分光光度法  单核  形态分析  方法选择  分析  实验结果  天然水  配位  桑色素  衍生试剂

Abstract:Fluorimetric method has been proposed for the speciation of Al in natural waters, based on the different competitive complexation behavior of analytical reagent and natural organic matter to Al. With eriochrome blue black R (EBBR) or morin, the monomeric inorganic Al (Al i) was determined, while with 8 hydroxylquinoline, the total monomeric Al (Al a) was obtained. The analytical results of Al speciation in natural water are close to those by Driscoll's method. The method is simple and reliable. Fractionation of Al was realized by selecting appropriate reagents under the pH of natural water determined. The merits of this novel strategy are that the disturbance to original equilibrium of Al species is minimized and the results conform to the actual situation of natural waters.
Keywords:Aluminum  Speciation  Eriochrome blue black R(EBBR)  Morin  8 hydroxylquinoline  Natural water  Fluorimetry
