采用微库仑法测催化柴油中的硫的质量分数,考察积分电阻、放大倍数等积分条件对测量结果的影响,并确定最优积分条件。在最优积分条件下,对用外标法配置的不同硫质量分数的催化柴油样品进行精密度和回收率的考察。实验结果表明,放大倍数为200、积分电阻为600Ω时,测得的硫质量分数误差小、重复性好。微库仑法操作简便、快速、准确,适用于大批量样品的测定。

The mass fraction of sulfur contained in the catalytic diesel was determined by micro-coulometry measurement,the effects of the integral resistance and magnification to the measurement results were investigated,and in addition,the optimal conditions were confirmed.Under the optimized conditions,precision and recovery rate of the external standard samples on catalytic diesel were investigated,and showed that the sulfur content measured with pretty good accuracy and repeatability with a magnification of 200 times,integral resistance of 600 Ω.It was a simple,rapid and accurate method for measuring large quantities of samples.
