Determination method for trace polycyclic aromatic hydrocarbons in paddy soils by HE Mingjiang, SHEN Haoran, ZHA Ting, YU Xiongsheng, LIU Xingmei

“…The PAHs are usually extracted and purified by organic solvent prior to determination. In order to improve determination accuracy and recovery rate, the pretreatment conditions for the determination of 16 PAHs in paddy soils are of great significance.On the basis of former work, in order to get the highest extraction efficiency and recovery rate, we compared two different extract solvent mixtures, four different clean-up columns and three different elution solutions, and also compared the elution volume and temperature of nitrogen blowing to optimize the determination method for trace PAHs in paddy soils under the laboratory condition. …”
