铁(Ⅲ)显色体系的研究

Study on Colour Reaction System of Iron(Ⅲ)

从pH试纸的制作中得到启发。通过对显色剂、氧化剂、缓蚀剂、缓冲体系的分别选择确定一种简便易行,效果良好的显色体系的组成成分。利用显色剂与不同浓度铁离子溶液进行显色反应制得标准色阶。将显色体系溶液喷涂到钢铁基材表面进行显色反应,对照标准色阶对钢铁锈蚀程度定量分析。

Gain enlightenment from the preparation of pH test paper,through the selected of color reagent,oxidant,corrosion inhibitor and buffer system,a simple and effective composition of colour reaction system is identified.Use of color reagents reaction with different concentrations of iron（III）solution make the standard color levels.Sprayed the colour system to the surface of the steel substrate to have color reaction,contrast the standard color levels to analyse to the steel extent of corrosion.
