摘　　要：试样经高温灰化后,硝酸处理。采用电感耦合等离子体发射光谱仪测定汽油中铅、锰、铁和磷含量。结果表明,铅、锰、铁和磷含量在0—10μg/L范围内线形关系良好,r=0.999,RSD为1.68%—5.00%,回收率96.0%—104.9%。The lead,manganese,iron and phosphorus in the samples were treated with nitric acid after ashes at high temperature,and the amout of lead,manganese,iron and phosphorus were determined by Inductively coupled plasma emission spectroscopy.The linear relation of detection is in the range of 0—10μg/L for lead,manganese,iron and phosphorus,with the relative standard deviation of 1.68%—5.00%and the relative coefficient of 0.999.The recovery is 96.0%—104.9%.
