摘要
利用5-溴水杨基荧光酮、CTMAB与Fe(Ⅲ)、Ti(Ⅳ)形成的三元配合物显色体系,采用联机检测技术,结合流动注射方法,对双组分金属离子进行了速差动力学同时测定的研究,并且测定了电铸液中Fe(Ⅲ)的含量.结果表明,方法不仅扣除了Ti(Ⅳ)的干扰,而且测定了Ti(Ⅳ)的含量.方法的回收率在96%～106%之间.样品处理手续简便,电铸液中其它组分基本不干扰测定.
The computerized kinetic FIA method was developed for the simultaneous determination of mi-croamounts of Fe (Ⅲ) and Ti (Ⅳ) in electrocasting solution by the coloration system of 5-bromosalicylfluorone in the presence of CTMAB. By the use of reaction rate difference-kinetic method the determination of iron is carried out by compensating the interference of Ti ( Ⅳ) and simultaneously Ti ( Ⅳ) is also determined. The recovery is 96%-106% and the sample processing procedure is simple. Other components present in the electrocasting solution do not interfere.
