  A multilayer analytical element has been prepared for use in the accurate colorimetric determination of lithium ion found in aqueous specimens. The element includes first and second reagent layers underneath a porous spreading layer. A more precise assay at longer read times of dye formation and reduced rate of background dye development are achieved because the second reagent layer contains both an aromatic phenol organic solvent and a perfluoroalkyl surfactant which were formerly included only in the first reagent layer. A 14-crown-4-ether derivative dye is used to complex with lithium ion to provide the colorimetric signal.

  我们制备了一种多层分析元件，用于对水样中的锂离子进行准确的比色测定。该元件包括位于多孔铺展层下面的第一和第二试剂层。由于第二试剂层同时含有芳香族苯酚有机溶剂和全氟烷基表面活性剂，因此可以在更长的染料形成读取时间内实现更精确的检测，并降低了背景染料的显色率。14-crown-4-ether 衍生物染料用于与锂离子络合以提供比色信号。
