X射线荧光光谱测定灯用煤油中的微量硫

DETERMINATION OF TRACE SULFUR IN ILLUMINATION KEROSENE BY X-RAY FLUORESCENCE SPECTROMETER

本法利用波长色散X射线荧光光谱仪测定灯用煤油中的硫 ,测量精密度较好 ,加标回收率为 90 .4 %～ 10 8.9% ,检测限 (LLD)为 0 .6× 10 - 6 (ws)。

Trace sulfur in illuminating kerosene was measured by sequential X-ray fluorescence spectrometer. The experimental results show that the precision are acceptable, and recovery is 90.4%～108.9%,the lower limit of detection (LLD) is 0.6ppm.
