喷气燃料中铜含量测定的误差分析

An Analysis to Deviation of the Measurement of Copper Content in Jetfuel

在针对一些轻质石油产品的分析中 ,铜含量的分析会得到经常的应用 ,尤其对于喷气燃料而言 ,铜含量的多少 ,直接关系到喷气燃料的重要质量指标———热安定性的好坏 ,因此铜含量的测定对于喷气燃料的质量控制有着重要的意义。SH/T182 - 92是现行的铜含量的测定方法 ,在一些情况下 ,该分析方法的偏差较大。通过对该方法的一些改进 ,尤其是在显色时 ,采用分步显色的方法 ,大大提高了分析的精度 ,使该方法得到了一定的充实和完善。

The analysis of copper content is frequently used in the anlysis of light petroleum products. The content of copper in jet fuel is diectly related to the important quality index of jet fuel-the level of thermal stability; therefore, copper content measurment is of significance to the quality control of jet fuel. SH/T182-92 is a method on copper content measurment in use at present. But under cerfain conditions,this method can be resulted in relatively abvious diviation. By making some improvement of this method,such as carryingout the color development measurement step by step, which greatly improves the accuraty og the analysis. And the method of the copper content measurement, has been fairly improved.
