摘　　要：水杨基萤光酮－溴化十六烷基三甲基铵分光光度法测定锌黄青瑜，童式国，刘小虎，杨映辉（四川大学化学系，成都６１００６４）关键词：锌，水杨基萤光酮，人发，分光光度法微量锌的测定方法是比较多的，如近年来发展较快的有高灵敏显色的萤光酮衍生物等。而水杨基萤光酮，...Thecolour reaction of a reagent ,salicylfluorone(SAF),with zinc in the presenceof CTMAB was studied.A stabie complex is found in the medium of PH 8.5.The maxi-mum absorption of the complex occurs at548nm,The apparent molar absorptivity at548nm is 5. 01×10￣4L· mol￣(-1). cm￣(-1).bollows Zine in the range of 0-30.0μg/25ml,The molar ratio of Zn(Ⅱ)to SAF being 1 :2,the method has been sucessfully appliedto the determination of Zn content in hair.
