采用硝酸作为消解剂对样品进行微波消解，利用ICP-AES同时测定车用汽油中的Fe、Mn、Pb和Si元素。通过加标回收实验与方法精密度计算，验证了该方法所得数据的可靠性，各元素测定结果的相对标准偏差在1.77%～4.69%(n=6)之间，加标回收率在91.1%～108.0%之间。结果显示，与常规单一检测法相比，该法高效简便、灵敏准确。

Determination of iron, manganese, lead, silicon in gasoline for motor vehicles were studied by ICP-AES after digested by HNO3 in microwave system. The determination results showed the method was sensitive and accurate. The reliability of analytical data was checked by additional standard recovery test and method precision. Recoveries of the method for these elements were in the range of 91.1%~108.0%, with the RSD≤4.69%(n=6). Compared with the commonly used single-element analytical techniques, the proposed method has the advantages of more efficient and accurate.
