卡尔曼滤波分光光度法用于铝、镓和铁的同时测定——铬天青 S-溴化十六烷基三甲胺法

Simultaneous Determination of Al(Ⅲ),Ga(Ⅲ) and Fe(Ⅲ) by Kalman Filter—Chromazurol S(CAS) and Cetytrimethylammonium Bromide (CTMAB) Spectrophotometry

本文运用卡尔曼滤波(KF)递推算法,通过三元络合物显色体系:CAS-CTMAB-Me,实现了Al(Ⅲ)、Ga(Ⅲ)和Fe(Ⅲ)三元素的同时测定,合成样分析结果良好。

Kalman Filter(KF)used as a“chemometries filter”can filter out the interferences from each other. By KF a spectrophotometric method for simultaneous determination of Al (Ⅲ), Ga (Ⅲ) and Fe (Ⅲ) with CAS and CTMAB is described. The procedure is accurate and selective. The method has been applied to the analysis of the synthetic samples with satisfactory results.
