| | CESFS has been applied to the determination of mixtures of PAHs: BaP,BeP,AN,PY and PE. When an appropriate Δν is chosen, these components can be well detected simultaneously by this method, and it is simple, rapid and sensitive.Furthermore,good resultscan be obtained for environmental samples. | | 本文以恒定能量差的同步荧光光谱对BaP、BeP、AN、PE和PY五种组分的多环芳烃混合物进行分析研究,结果表明,选择合适的能量差,能同时定量分析出其中四种组分,特别是对致癌性强,而在常规荧光光谱中干扰严重的BaP不必预分离就直接测定有重要意义。该方法简单,快速,灵敏。本文还将此方法用于十七种PAHS的混合物,及大气样、底泥和柴油机尾气样的研究,获得良好的效果。 | | 文摘来源 | | Simultaneous quantitative analysis phenol and dichlorophenol by the derivative of absorbance ratio method has been developed. The sensational linear relationship between derivative of absorbance ratio and correspond concentration has been approved when the phenol concentration under 9 mg/L as well as dichlorophenol below 7 mg/L. Relative standard deviation of phenol and dichlorophenol is 1.35~0_0 (n=12) and 2.02~0_0(n=12) respectively. | | 据吸光度比值导数光谱方法的原理,采用了普通分光光度计同时定量分析测定苯酚和2, 4 二氯苯酚。实验表明,苯酚浓度<9mg/L、及2, 4 二氯苯酚浓度<7mg/L时,吸光度比值之导数相应物浓度间呈现线性关系。误差实验显示,苯酚的测量平均相对误差1. 3500(n=12), 2, 4 二氯苯酚的测量平均相对误差2. 0200(n=12)。 | | 文摘来源 | |   |
