| Abstract | HEEP COPYRIGHT: BIOL ABS. A method for determing the hydrocarbons dissolved in sea water, including their concentration and separation into homogeneous classes, was described. Extraction with organic solvents, determination of the optimum volumes for n-hexane and CCl4 and concentration procedures for the extracts were investigated. Separation of hydrocarbons from polar compounds and their fractionation into 5 classes (aliphatic, monoaromatic and polynuclear with 2, 3-4 and 5-6 rings) were achieved using adsorption chromatography on a 2-step microcolumn of silica gel and aluminium oxide. The overall recovery efficiency of the procedures and the detection limits of several hydrocarbons in 11 sea water were reported. |
