Application of headspace gas chromatography to the determination of chlorinated hydrocarbons in waste waters

A method is described for the determination of C 2 chlorinated hydrocarbons in waste waters. The headspace method was used for the quantitative analysis. The method was tested for individual components in the concentration range of 0.5–200 ppm. The efficiency of the purification of waste waters from industrial plants was determined by the method described. For quantitative analysis the external standard method was applied.

Determination of polycyclic aromatic hydrocarbons in industrial waste water at the ng/ml. level

A combination of column, thin-layer and capillary gas chromatography was investigated as a quantitative method for determination of polycyclic aromatic hydrocarbons in industrial waste water at the 10–100 ng/ml level. The method gives 90–95% overall recovery. Analytical results for polycyclic aromatic hydrocarbons in waste water from a Norwegian aluminium plant are presented.
