同步荧光法同时测定地面水中的苯酚和苯胺
SIMULTANEOUS DETERMINATION OF PHENOL AND ANILINE BY SYNCHRONOUS FLUORIMETRY
【摘要】 苯酚和苯胺的常规荧光光谱互相有干扰。应用固定波长同步扫描法可同时测定苯酚和苯胺。当介质的酸度pH=6.0及波长差△λ为20nm时,苯酚同步荧光峰波长276nm,测定范围为0.010-3.0μg/ml,检测限5ng/ml;苯胺同步荧光峰波长300nm,测定范围0.10-2.0μg/ml,检测限30ng/ml.
【Abstract】 A measurement method of synchronous fluorimetry for the simultaneous determina-tions of phenol and anlline is carried out in a Britton-Robinson buffer solution(pH6.0) with△λ20nm for synchronous scanning,which gives peaks at 276nm and 300nm for phenol and anilie ,espectively.The Linear ranges of the determination are 0.010 to 3.0μg/ml for phenol,0. 10 to 2.0μg/ml for aniline.The determination gaves a relative standard deviation of less than 6.7%.
