| 摘 要： | 在稀硫酸介质中及草酸存在条件下，痕量铁对金芝花橙ＯＯ对光化学褪色反应有较催化作用，在氢氧化钠介质中中，金莲花橙ＯＯ于－０．８０Ｖ处产生一灵敏的２．５次生分极谱波。采用２．５微分极谱法研究了Ｆｅ（Ⅲ）－草酸－金莲茶橙ＯＯ光化学新体系，建立了一个检出限和测定范围分别为０．７ｎｇ／ｍＬ和２ｎｇ／ｍＬ－１００ｎｇ／ｍＬ铁的光学伏安分析新方法，并用于试样分析。

| Abstract: | A novel photochemical voltammetric method for Fe was described,based on its catalytic effect on the photochemical reaction of tropaeolin OO irradiated by UV light under the conditions of pH 2 0 and existence of oxalic acid as activator,in which tropaeolin OO (E p=-0 80 V) could be measured by 2 5 order differential voltammetry. A calibration graph from 2 to 100 ng/mL Fe and detection limit of 0 7 ng/mL were obtained by the fixedirradiation time procedure.Iron in tea and water samples was also analysed. |
