摘要
阐述了紫外荧光法测定油品中硫含量的分析原理和分析步骤,通过具体研究实验条件(进样量、裂解温度、气体流量及进样速度等)对测定结果的影响来寻找测定的最佳实验条件,并通过建立标准曲线来测定油品中硫的含量。检验了方法的精密度和准确度。结果表明:在适当的实验条件下,用紫外荧光法测定油品中硫含量具有较高的精密度、准确度和回收率。
The analysis principle and the analysis step of ultraviolet fluorescence method for determination of sulfur in petroleum products was proposed in the paper, Seeked the best experimental conditions of the determination by study the effect of experimentation conditions（Specimen handling quantity, decomposition temperature, gas flow rate and specimen handling speed and so on）to the results, and sulfur in petroleum products was analyzed by establishing calibration curves. The precision and accuracy were presented. The results showed that： Under the suitable experimentation condition, the determination of sulfur content in petroleum products had the higher precision, accuracy and returns-ratio with the ultraviolet fluorescence method.
