该文采用N2O/C2H2FAAS和FAES两种方法同时测定正常人头发中的铝,并对测定条件、干扰物质的影响及测定结果进行了比较.实验表明,在酸性介质中,选择396.1NM发射线,不论是物质的干扰程度、还是测定的精确度、灵敏度和回收率,FAES法均优于FAAS法.其对应的RSD(N=9)分别为2.2和2.7%,检出限分别为0.07和0.25μG/ML.在1.0G头发样品中加入20.0μG铝,其回收率分别在96.5~105.0%和93.5~106.5%之间.“,”In this paper,two methods of N?2O/C?2H?2 FAAS and FAES are applied to determine aluminium in healthman hair.The requirement of determination,interferences of inorganic ions and organic substances and the results of determination are contrasted respectively.It is shown experimently that the interference ratio of substances,accuracy,sensitivity and recovery ratio of FAES are superior to FAAS at 396?1nm wavelength in acidity medium.The RSD (?n=9?) of FAES and FAAS are 2?2 and 2?7%respectively and detect limi...
