摘要
介绍一种利用高效液相色谱定量检测绝缘油中腐蚀性硫（二苄基二硫）的方法,可为绝缘电气设备的状态评价提供更多依据.使用甲醇萃取和固相萃取两种样品前处理方法,可有效分离油样中的杂质,使二苄基二硫质量浓度在0～500 mg/L范围内线性良好,测量结果准确可靠,灵敏度较高,精密度好;但样品前处理回收率较低,具体试验条件还需进一步优化.
A quantitative detection method of dibenzyl disulfide in corrosive sulfur in insulating oil by high performance liquid chromatography is introduced.h can provide more evidences for the state evaluation of insulation and electrical equipment.It can effectively separate the impurities from oil samples by these two sample pretreatment methods with methanol extraction and solid-phase extraction.The dibenzyl disulfide linearity in the range of 0mg/L-500mg/L is good,and the measurement results are accurate ,reliable ,high sensitivity and good precision ,but the recovery rate of the sample pretreatment methods is low, so the specific test conditions need to be further optimized.
