Research in environmental pollution

IX. A new micro method for the extraction of polychlorinated biphenyls (PCB's) from sewage sludges

Original Papers Environmental Analysis


Sewage sludges are treated with concentrated sulphuric acid and coated on silica gel. For the extraction and clean-up steps only a total solvent amount of 20 ml is necessary. The results of this “H2SO4-method” are compared with already tested micro extraction methods. It was found that the proposed method is equally effective and can therefore be used for routine analysis. The reduction of solvents and chemicals waste by miniaturisation of analytical procedures is an important step for environmental protection.
