| 摘 要： | 邻苯二酚和对苯二酚是有毒物质,酪氨酸和色氨酸是天然氨基酸中仅有的会发光的组分,由于四组分光谱重叠,很难用常规方法直接定量检测.实验中采用三维荧光光谱结合平行因子和自加权交替三线性分解算法,邻苯二酚、对苯二酚、酪氨酸和色氨酸进行直接定量测定;同时,比较两种算法在定性测定和定量测定上的差别.当测量体系的成分数预估计值为4时,两种方法分辨后的回收率分别为(101.2±2.7)%,(99.3±3.0)%,(98.7±4.5)%,(101.6±4.7)%和(109.0±8.0)%,(91.3±11)%,(99.7±13)%,(98.1±11)%.试验结果表明,两种方法可用于四组分直接快速定量测定;通过对两种算法的比较,PARAFAC算法更具优势.

| Abstract: | Catechol and hydroquinone are toxic substances,while tyrosine and tryptophan are luminescent substances in natural amino acids. Because of spectra overlap of the four components,it is difficult to detect quantity directly with conventional methods. A simple and reproducible method which provides simultaneous determination of catechol,hydroquinone,tyrosine and tryptophan in the same samples is presented in the present paper. The method combined excitation-emission fluorescence spectra with PARAFAC and SWATLD... |
