摘要: 本文对工业污水中,石油烃类分析的紫外吸收光度法,进行了删繁就简的试验。实验表明,石油烃萃取溶剂石油醚的透光率T,可以在很大范围内应用,可以简化或省略脱芳净化。脱水剂硫酸钠用量必须适当,否则会产生负偏差。分析中,标准油样可用具有代表性的单一油品代替。

Abstract: The author tries to simplify the ultraviolet absorption spectrophotometric method in analying petroleum hydrocarbons. The experiments have shown that the transmittancy T of extract solvent petroleum ether can be applied in a larger range, and the dearomatic purification can be simplified or even be omitted. Beinga dehydrating agent, the dehydrated sodium sulfate must be used properly, otherwise a negative derivation would occur. In analysis, the standard oil sample can be replaced by a representative single oil.
