摘　　要：目的建立适用于面制食品中铝含量的分光光度检测方法。方法样品经微波消解法或湿消解法消解后,用分光光度法测定食品中铝的含量。结果铝浓度在0.25～5.0μg/ml范围内呈现良好的线性关系,相关系数r=0.9998。检出限(LOD)为:2.3ng/ml;定量限(LOQ)为:7ng/ml。结论该方法用于面制食品中铝含量的测定,方法简便、快速,结果准确可靠。Objective To establish a determination method for aluminium in flour foods with photometric method. Methods After samples being treated with microwave digestion and wet digestion, aluminium in staple flour foods was determined by photometric method. Results There was a good linearity of the result in the range of 0.25 -5.0μg/ml aluminium, r = 0. 9998 ; limit of detection（LOD） ：2. 3ng/ml; limit of quantitation（LOQ） ：7ng/ml. Conclusion This method of determining aluminium in flour foods is simple, rapid and reliable.
