摘要
应用电感耦合等离子体原子发射光谱法测定燃料油中硫元素含量。采用硝酸-过氧化氢作为消解剂,对燃料油样品进行微波消解处理,选择180.7 nm谱线作为分析线,对SRM2724b柴油标准物质、国产101煤油和-10#柴油3种燃料油中的硫元素进行测定,3种燃料油测定结果的相对标准偏差均小于5%(n=6),SRM2724b柴油标准物质硫含量的测定值与标准值基本相符。
Sulful in fuel oil was determined by ICP-AES method.Nitric acid and hydrogen peroxide were used as digestion agent to pertreat fuel oil samples by microwave digestion.The spectral line 180.7 nm was selected as the analytical spcatral line.SRM 2724b diesel fuel standard material,101 kerosene and-10#diesel fuel were tested,the relative standard deviations of the detection results were all less than 5%(n=6).Sulful content in SRM 2724b diesel fuel standard material was determined and the determination value was in consistency with the standard value.
