MEASUREMENT OF SOIL POLLUTION |
摘要 |
A soil sample of fixed volume is mixed with a drying agent (MgSO4) and then acetone. The liquid is filtered off and a sample is applied to the sensing surface of an attenuated total reflectance (ATR) device in an IR spectrometer. After evaporation of the acetone, absorption is measured in a C-H stretch region (e.g. 2950 cm-1) to provide a value indicative of the amount of oil in the sample.
