A.2 Infrared spectroscopy method
A.2.1 Extraction and preparation of the extract
An effluent sample of approximately 500 ml is weighed into a separating funnel with a rated volume of 1000 ml,
directly from the sampling device (see Figure A.1). Within 15 min of sampling the pH shall be set to between 1 and
2 using sulphuric acid (H SO ) and 50 ml of 1.1.2-trichloro-1.2.2-trifluoroethane (C Cl F ) shall be added. It is then

immediately shaken, with a frequency of 3 Hz to 4 Hz for 10 min and the phases allowed to settle for 30 min.
Alternatively, tetrachloroethylene (C Cl ) (IR grade) may be used as the extraction solvent.

If the samples have to be transported to an external laboratory, they shall be weighed into glass bottles. The
samples shall be preserved within 15 min by addition of acid as described above. They shall either be further
preserved by addition of 1.1.2-trichloro-1.2.2-trifluoroethane as above before transport, or they shall be sent to the
analysis laboratory at 4°C. If preserved by solvent, at the analysis laboratory the samples shall be transferred to
separating funnels for extraction as above. If the samples have been refrigerated then the solvent should be added
to the sample bottle, then transferred to separating funnels for extraction as above.
After phase separation the organic fraction is run off and immediately filtered through approximately 10 g of
anhydrous sodium sulphate (Na SO ) into a volumetric flask with a rated volume of 50 ml. The extract is made up

the sodium sulphate.
A.2.2 Evaluation
Measurement is made against a reference of the pure solvent of same layer thickness using matched cuvettes of
equal length. Before measurement, a transmission value of exactly 100 % shall be set with the cuvettes inserted, at
3,2 µm. Those absorption bands showing 3,38 µm and 3,42 µm shall be recorded.
The mass concentration of the hydrocarbons in the water sample is obtained from:
