摘　　要： 主要应用了石墨炉原子吸收光谱法塞曼扣除背景方式,在镀钼涂层的平台石墨管中直接进样测定葡萄酒中的铝含量。研究了石墨炉各主要工作条件对吸光度的影响,确定了该方法的最佳条件:0—100μg/L范围内呈线性关系;仪器的检出限为1.7μg/L;应用此方法测定了几种不同样品中铝含量,测定值的相对标准偏差(n=10)在2.28%—3.94%之间,在样品中做回收实验测得回收率在97%—102%之间。 Background overcompensation in Zeeman-corrected was used in the directly injection determination of aluminum in wine by GFAAS with molybdenum-coated platform tube.The influences of main work conditions on absorbency were discussed,and the best conditions were confirmed to keep linear relationship in the range from 0—100μg·L-1.The aluminum in several samples were analyzed by this method.The RSD（n=10） were obtained in the range from 2.28%—3.94%.The recovery for the samples were made between 97% and 102%.
