Research on Determination of Volatile Organic and Inorganic Substances in Sandy Soil

Four detecting methods are separately adopted to measure the volatile organic and inorganic components in sandy soil including purge and trap-gas chromatography/mass spectrometry and headspace-gas chromatography/mass spectrometry and X ray fluorescence spectrometry and spectrophotometry with silver diethyldithiocarb nate(Ag-DDC).It is detected that the soil consists of a kind of poisonous mineral-arsenous compound and five varieties of volatile organic matter such as 2-ethyl-hexanol and n-octyl alcohol and others.
