摘要

人体中铁元素含量过多会引起人体组织损坏、皮肤色素沉着、肝脾功能性障碍等病状。研究利用Fe³⁺与邻香兰素乙醇溶液反应生成藏蓝色络合物的特性，实现了对溶液中Fe³⁺的快速检测。邻香兰素乙醇溶液对Fe3+有较强的选择性。在Fe³⁺浓度为0～200 μM的范围内，不同浓度的Fe³⁺的紫外光的吸收大小与Fe³⁺浓度呈良好的线性关系（R=0.99299）,邻香兰素乙醇溶液对Fe³⁺的检测限约为1 μM。

Abstract:

Excessive iron content in human body can cause human tissue damage, skin pigmentation, liver and spleen dysfunction and other symptoms. In this paper, the reaction of Fe³⁺ with o-vanillin ethanol solution to form the dark blue complex was studied. O-vanillin ethanol solution has strong selectivity to Fe³⁺. In the range of Fe³⁺ concentration 0～200 μM , the ultraviolet light absorption of Fe³⁺ with different concentrations showed a good linear relationship with Fe³⁺ concentration (R=0.99299), the detection limit of o-vanillin ethanol solution on Fe³⁺ was about 1 M.

Key words: o-vanillin colorimetry Fe³⁺ complexation reaction
