摘要
用紫外荧光法测试了液态石油烃中的痕量硫。以二甲苯作稀释剂,在0.05～1000 ng/μL浓度范围内测定结果的相对标准偏差小于3％,硫的回收率为96％～104％。该法简便、快捷。
The trace sulfur in liquid petroleum hydrocarbons was determined by ultraviolet fluorescence with xylene as diluting solvent. RSD was less than 3% and recovery was 96% - 104% in the concentration range of 0. 05 - 1 000 ng/μL. This method is a rapid and easy way.
