石油烃测定方法和标准使用建议

Suggestions for the Method and Standard Use of Petroleum Hydrocarbon Determination

石油类中含有石油烃类物质,石油烃类物质中主要的毒性来源于多环芳烃。不同行业的国内外标准中有多种石油烃类物质的测定方法,主要包括重量法、气相法、红外法、紫外法和荧光法。不同方法各有其优缺点。全面比较了各方法的原理和应用范围,给出今后实际检测和标准修订的建议以供参考。

Petroleum contains petroleum hydrocarbons,and the main toxicity of petroleum hydrocarbons comes from polycyclic aromatic hydrocarbons.There are many methods for determination of petroleum hydrocarbons in domestic and foreign standards of different industries,including gravimetric method,gas chromatography method,infrared method,ultraviolet method and fluorescence method. Different methods have their own advantages and disadvantages.This paper comprehensively compares the principle and application scope of these methods,and gives suggestions for future practical testing and standard revision for reference.
