多波长线性回归荧光法同时测定苯酚、间苯二酚和间苯三酚

Simultaneous Determination of Phenol, Resorcinol and Phloroglucinol by Multiwavelength Linear Regression Fluorimetry

酚类物质是环保、卫生、医药、食品等行业分析的重要指标，通常只能测定酚的总量［１～３］，最小二乘法［４］、卡尔曼滤波法［５］虽能同时测定各量，但需要用计算机解谱，且只进行了苯酚和间苯二酚两组分的测定．对于结构相似的苯酚、间苯二酚和间苯三酚三组分混合体系...

The fluorescence spectra of the mixture of phenol, resorcin and 1,3,5 trihydroxybenzene have been analyzed by multiwavelength linear regression method. In a buffered pH=6 86 solution the detection limit of phenol, resorcin and 1,3,5 trihydroxybenzene was found to be 0 48, 0 51 and 0 67 μg/L, respectively. The method has been applied to the simultaneous determination of the above phenols in the synthetical samples and pharmaceutical preparations with recoveries being in the range of 93 7%￣106%.
