摘　　要：文章依据GB/T12689.1—2010,通过酸度试验、试剂加入量和加标回收试验、精密度试验等,对铬天青S分光光度法快速测定锌锭中的铝含量的检测方法进行了优化。该法相比原方法减少了调节pH值的步骤,且减少了三种其它试剂的加入。加标回收率为98.93%~100.82%,方法相对标准偏差为4.28%~6.43%。According to GB/T 12689.1-2010,the determination method of aluminum content in zinc ingot by chrome azurol S spectrophotometry was optimized through acidity test,reagent addition and recovery test,precision test,etc.compared with the original method,this method reduces the steps of adjusting the pH value and reduces the addition of three other reagents.The recoveries was 98.93%~100.82%and the relative standard deviations was 4.28%~6.43%.
