采用ICP-AES有机进样法测定燃料油中铝、硅、钙、钒、铁、镍元素。采用航空煤油为稀释剂,按照油/溶剂(质量比)1/9加以稀释后直接进入ICP-AES(电感耦合等离子体发射光谱)仪器测定。方法检出限:钒为0.5μg/g,硅为1μg/g,铝、镍为0.2μg/g,铁、钙为0.05μg/g;相对标准偏差<5%;回收率在88.4%～109.8%之间;与无机灰化-碱熔法(IP 501/05)测定的结果进行了比对,结果基本一致。
Determination of aluminum, silicon, calcium, vanadium, iron and nickel in fuel oil by ICP-AES. Using aviation kerosene as a diluent, dilute 1/9 of the oil / solvent (mass ratio) directly into an ICP-AES (Inductively Coupled Plasma-Atomic Emission Spectrometer) instrument. The detection limits were as follows: vanadium 0.5μg / g, silicon 1μg / g, aluminum and nickel 0.2μg / g, iron and calcium 0.05μg / g; relative standard deviation <5%; recoveries 88.4% -109.8 %; Compared with the results of inorganic ashing-alkali fusion method (IP 501/05), the results are basically the same.
