摘要
研究了微波消解燃料油样品的体系和程序,建立了燃料油中磷含量的测定新方法-磷钼蓝光度法。结果表明,在最佳实验条件下,磷的线性范围为0～1.0μg/mL,RSD为2.06～2.47%,回收率为99.13%～104.10%。方法具有高准确度和低检出限,适用于燃料油中磷的测定。
The microwave digestion system and program of fuel was studied, and a new method for the determination of phosphorus in fuel named phosphor - molybdenum blue spectrometry was established. The test results indicate that the linear range of phosphorus is 0 - 1.0 μg/mL, RSDs were in the range of 2.06 -2.47%, and the recoveries ranged from 99. 13% - 104.10% under the optimum determination conditions. This method was convenient,rapid and accurate, which was suitable for the determination of phosphorus in fuel.
