摘　　要：分别采用紫外荧光法、化学发光法和微库仑法测定柴油、120#溶剂油中的总硫、总氮含量,并进行了对比分析。结果表明,三种分析方法都具有较高的精密度和灵敏度,无显著性差异。Total sulfur and total nitrogen in diesel oil and 120# solvent naphtha were determined by UV fluorescence method, chemiluminescence method and microcoulometry, respectively. The experimental results were studied comparatively. It is demonstrated that all thesemethods have relatively high precision and sensitivity and their analytical results have no significant difference.
