摘　　要：通过对GB/T 5009.182-2003中铝检测方法-铬天青S分光光度法进行改进,表明在0.0-8.0μg范围内,其线性关系良好,回归方程y=0.197 7 x-0.036,R2=0.999 5,精密度高,相对标准偏差为2.6%,准确度高,样品加标回收率为97.3%-104.8%;样品经送第三方检测机构按GB/T 23374-2009《食品中铝的测定电感耦合等离子体质谱法》检测,两者结果误差在10%以内,准确度高。By improving GB/T 5009.182-2003 aluminum Detection-Chromium Azure S Spectrophotometry the result indicated that, there was a good linear relationship in range of 0.0-8.0 μg, y=0.197 7 x-0.036, R2=-0. 999 5. The relative standard deviation was 2.6%, sample added recovery was 97.3%-104.8%. The sample was sent to the third-party testing organization according to GB/T 23374-2009 ＂food in aluminum Inductively coupled plasma mass spectrometry＂ test, the result error was within 10%.
