A simple and sensitive method for the determination of carbaryl in whole blood and commercial formulations, based on normal, and synchronous first- and second-derivative fluorescence spectra, is presented. Solvent effects on the spectral characteristics of carbaryl solutions and the influences of instrumental parameters are described in detail. Two methods have been developed, with neutral (for carbaryl) and basic (for 1-naphthol) media. Detection limits of 0.9 and 0.7 ng/ml were achieved for carbaryl and 1-naphthol, respectively, with the first-derivative approach.
本文提出了一种基于常规、同步一阶和二阶导数荧光光谱测定全血和市售制剂中西维因的简单灵敏方法。详细描述了溶剂对西维因溶液光谱特性的影响以及仪器参数的影响。已开发出两种方法，分别用于中性（针对西维因）和碱性（针对1-萘酚）介质。采用一阶导数法时，西维因和1-萘酚的检测限分别为0.9和0.7 ng/ml。
