摘要
利用芳胺的重氮化偶合反应 ,采用误差反向传播人工神经网络方法 ,对于吸收重叠的3组分芳胺类化合物体系进行同时测定 ;并用该法测定了以高压紫外汞灯为光源 ,纳米金红石相TiO2 为催化剂 ,光催化降解苯胺、甲萘胺、邻氯苯胺3组分过程中各组分浓度 ;实验证明对合成样本与催化体系样本 ,回收率均在91 %～108 %之间,其结果准确可靠。
A method for the determination of arylamines,aniline,α-naphthylamine and o-chloraniline,which absorption spectra are seriously overlapped,was proposed by back propagation artificial neural network(BP- ANN)-spectrometry based on the diazo coupling reaction of arylamines withα-naphthol.The experimental conˉditions were optimized and the parameters for the BP-ANN were selected.The recoveries of91%～108%of the arylamines for the method were obtained.The method was applied for the simultaneous determination of contents of aniline,α- naphthylamine,and o-chloraniline in photocatalytic degradation process with titanium dioxide rutile nanoparticles as a catalyst.
