Abstract

Leakage of oil and petroleum products can cause serious soil pollution. Traditional monitoring method for soil petroleum hydrocarbon pollution finds it difficult to diagnose a large area of soil contaminated area, while visible and near infrared (VNIR) spectroscopy technology boasts advantages like fast and convenient. Therefore, it is the most promising means to rapid acquisition of soil information, and the trend of future research. The experiments are designed to simulate different degrees of pollution under the actual conditions, and the spectral characteristics and differences of the different types of petroleum hydrocarbon contaminated soil are measured and analyzed by the method of VNIR spectroscopy. The study shows: (1) When the content of petroleum hydrocarbon is the same, the spectral reflectance of engine oil contaminated soil is lower than that of diesel oil and gasoline contaminated soil; spectral response characteristics of soil containing diesel oil and engine oil are in the depth of 1206nm and 1728nm, which spectral response characteristics of soil containing gasoline is in the depth of 1192nm and 1707nm. And their absorption depths in the response characteristics are as engine oil, gasoline and diesel oil, from big to small. (2) With the increase of petroleum hydrocarbon pollution, the absorption depth of water absorption Valley at 1423nm decreases first and then increases, which can be used as an auxiliary basis to identify soil petroleum hydrocarbon pollution.
