协同增敏同步荧光法测定自来水与人尿中的1-羟基芘
Determination of 1-Hydroxyl Pyrene in Tap Water and Human Urine by Enhanced Synchronous Fluorescence Spectrometry with β-Cyclodextrin and n-Propyl Alcohol
【摘要】 使用正丙醇这一小分子脂肪醇,进一步促进β-环糊精有序介质对1-羟基芘的荧光增强作用,基于此,利用同步荧光法测定水样中的1-羟基芘,检测限达到2.5×10-11m ol/L,相对标准偏差为3.8%(n=5),运用该方法测定了自来水与人尿样品中的1-羟基芘,结果满意。
【Abstract】 Joint use of β-Cyclodextrin and n-propyl alcohol can enhance synchronous fluorescent intensity of 1-hyroxyl pyrene(1-HP) greatly.Based on this phenomenon,experiments were carried out,a new method for the determination of 1-HP established by enhanced Synchronous Fluorescence Spectrometry.The limitation of determination of this method was 2.5×10-11 mol/L,RSD=3.8%(n=5).Tap water and human urine samples were determined by this method,and satisfying data were gained.
