The color reaction between iron(Ⅲ) and p-diethylamine phenylfluorone(p-DEMPF) was studied. In a NHCl-NH ·HO buffer solution with pH 9.00 and in the presence of tetradecyl pyridine bromide(TPB),iron(Ⅲ) reacts on p-DEMPF to form a bluish violet complex. |
中文意思: 在pH 9.00的NHCl-NH .HO缓冲体系中,铁(Ⅲ)与对二乙氨基苯基荧光酮(p-DMEPF),溴代十四烷基吡啶(TPB)反应生成三元蓝紫色配合物,其吸光度值与铁(Ⅲ)的浓度成正比,据此建立了测定微量铁的分光光度新方法。 |
