摘　　要：探讨了电感耦合等离子体发射光谱法（ICP-AES）测定铝锰铁合金中铝、磷、硅的分析条件。试样经盐—硝混合酸分解,于同一试液中测定铝、磷、硅。铁、锰的背景干扰采用背景校正扣除。方法的相对标准偏差（n=7）为0.6%~3.7%,加标回收率为96%~103%。The analytical conditions of determination of aluminum,phosphorus,silicon in aluminum-ferromanganese alloy by ICP-AES are discusses.The sample is dissolved by hydrochloric-nitric acid and elements of aluminum,phosphorus,silicon are determined in the same solution.Background interference of iron and manganese can be eliminated by background correction.The test result shows that the relative standard deviation（n=7） is 0.6%~3.7%,the recovery of standard addition is 96%~103%.
