摘要:
提出了氧弹燃烧-离子色谱法测定机油样品中Cl、S、P的方法.机油经氧弹燃烧分解，用NaOHH2O2吸收，离子色谱法以28 mmol/L的KOH为淋洗液，IonPac AS23型阴离子分析柱，抑制电导检测，可同时测定机油中Cl、S、P，各被测离子线性关系良好，相关系数为0.999 5～0.999 9，测定结果标准偏差小于3.75%，加标回收率为97.1%～101.20%.此法样品前处理操作简便，准确度高，重现性好.
Abstract:
A method was proposed for the determination of chlorine，sulfur and phosphorus in engine oil by oxygen bomb combustionIon Chromatography. Engine oil was first burnt in oxygen bomb，them the combustion products were absorbed in NaOH—H2O2 solution，which was analyzed by Ion Chromatography using 28 mmol/L KOH as mobile phase， IonPac AS23 separation column and suppressed conductivity detection. The relative standard deviation of chlorine， sulfur and phosphorus are lower than 3.75%，and the correlation coefficient range for the target ions and the recovery of this method are 0.999 5—0.999 9 and 97.1%—101.2%，respectively. The method is simple，accurate and good reproducibility for determining of chlorine，sulfur and phosphorus in engine oil.
