苯并(a)芘(Bap)的常规监测方法是将环境样品用有机溶剂提取,再经过一些预分离步骤,然后用紫外吸收或荧光法测定。这种方法繁琐、灵敏度低、精密度差。 同步荧光光谱方法的原理是由Llogd提出来的。由于它可以简化光谱及增大分析选择性,受到分析工作者的重视。 同步荧光方法用于Bap的分析,北京环科所的雷世寰已做了一些探讨工作。但 The usual monitoring method for benzo (a) pyrene (Bap) is to extract the environmental samples with organic solvents and then pass through some pre-separation steps followed by UV absorption or fluorimetry. This method is cumbersome, low sensitivity, poor precision. The principle of synchronous fluorescence spectroscopy is proposed by Llogd. Analysts are paying attention to because it can simplify the spectrum and increase the selectivity of the analysis. Synchronous fluorescence method for the analysis of Bap, Beijing Central Branch of the World has done some research work. but
