Abstract

The Total Petroleum Hydrocarbon (TPH) is the total of different types of hydrocarbons in the crude oil mixture. It includes volatile petroleum hydrocarbons and extractable petroleum hydrocarbons. The TPH determination techniques are primarily grouped into spectroscopic (ultraviolet spectroscopy, raman spectroscopy, fluorescence spectroscopy, infrared spectroscopy) and non- spectroscopic (gravimetric, immunoassay, gas chromatography with mass spectrometric detection (GC/MSD), gas chromatography with flame ionization detection (GC-FID)) techniques. Solvent and the sample characteristics determine the efficiency of the techniques. This paper compares spectroscopic (fourier transform infrared spectroscopy and ultraviolet spectroscopy) and non-spectroscopic (gravimetric and gas chromatography) methods in the determination of TPH in soil. Spectroscopic and non-spectroscopic techniques are efficient, but the paper recommends spectroscopic techniques because the techniques are efficient with small operational time, and are safer in occupational health and safety issues. In addition their results are accurate and reliable.

土壤中总石油烃测定技术综述

石油总烃(TPH)是原油混合物中不同类型烃的总和。它包括挥发性石油碳氢化合物和可提取石油碳氢化合物。TPH测定技术主要分为光谱法(紫外光谱法、拉曼光谱法、荧光光谱法、红外光谱法)和非光谱法(重量法、免疫法、气相色谱-质谱检测(GC/MSD)、气相色谱-火焰电离检测(GC- fid))技术。溶剂和样品的特性决定了技术的效率。本文比较了光谱法(傅里叶变换红外光谱法和紫外光谱法)和非光谱法(重量法和气相色谱法)测定土壤中TPH的方法。光谱技术和非光谱技术都是有效的，但本文推荐光谱技术，因为光谱技术效率高，操作时间短，并且在职业健康和安全问题上更安全。结果准确可靠。
