微量雾化系统-电感耦合等离子体原子发射光谱法测定汽油中8种有害元素的含量
Determination of 8 Harmful Elements in Gasoline by ICP-AES Using Microconcentric Nebulizing System
摘 要
用碳链的碳数与汽油样品近似的异辛烷以1：1的质量比稀释样品，并引入所选高效雾化系统处理。按经优化的操作条件，用电感耦合等离子体原子发射光谱法测定汽油中8种有害元素（铅、铁、锰、铜、磷、硫、氯和硅）的含量。上述8种元素的质量分数在一定范围内与分析信号之间呈线性关系。检出限（3s）在0.34~250 μg·kg-1之间。按标准加入法进行回收试验，回收率在94.4%~108%之间，测定值的相对标准偏差（n=7）在1.1%~4.9%之间。

Abstract
Isooctane, a solvent with similar carbon number in the carbon chain to that of the gasoline, was selected as the diluent for gasoline in the mass ratio of 1 to 1, and the diluted gasoline sample was introduced into the highly efficient nebulizing system. Eight harmful elements (Pb, Fe, Mn, Cu, P, S, Cl and Si) in the nebulized sample were then determined by ICP-AES under the optimized conditions of the instrument. Linear relationships between the values of analytical signals and mass fraction of the 8 elements were found in definite ranges, with detection limits (3s) in the range of 0.34-250 μg·kg-1. Values of recovery found by standard addition method were in the range of 94.4%-108%, and values of RSDs (n=7) found were ranged from 1.1% to 4.9%.
