摘　　要：通过探讨电感耦合等离子发射光谱法测定常规汽油中硅含量的影响因素,找出了测定常规汽油中硅含量的最佳操作条件:在硅谱线为251.612 nm、稀释比为1∶5、发射功率为1 050 W的条件下,雾化器的流量为0.6 L/min时,常规汽油中硅的回收率较高、标准偏差均小于5%,可得最佳试验结果。Basing on discussion of influencing factors in silicon content determination in conventional gasoline by inductive coupling plasma atomic emission spectrometry method,the optimal operation condition parameters were found.When silicon spectral line was 251.612 nm,ratio of diluent to the conventional gasoline was 1∶ 5,transmitting power was 1 050 W,and flow rate of the atomizer was 0.6 L/min,the recovery yield of silicon from the conventional gasoline was higher and the standard deviations were all below 5%,the optimal test results were obtained.
