The validation of the extraction method is significant for the characterization of the offset effluent and the selection of an adequate effluent treatment for its safe disposal in a printing environment. For the aforementioned reasons, the qualitative characterization of the organic load profile of the waste offset developer was evaluated based on the application of two liquid/liquid (L/L) extraction methods. The gas chromatographic/mass spectrometric (GC/MS) method was used for the qualitative detection of the organic compounds present in the offset effluent. The cumulative qualitative GC/MS profile of organic substances in the waste offset developer indicates that the effluent contains 69 organic compounds with a probability of presence higher than 70% according to the AMDIS software and the NIST database.

It is known that a series of organic compounds containing in molecule SH-, NH- qroups, including halogens, carboxylic acids and their derivatives, have the ability to form the innercomplex compounds under certain conditions. These compounds permit to carry out the extraction in acidic medium, that prevents the of process hydrolysis. They are not dissolved in water but are soluble in various solvents and form colored solutions and so may be used as an extractants. The main purpose of this paper is the study of palladium extraction ability for chlorinated naphthenic acids (CNA) synthesited in laboratory on the basis of industrial alkylphenols. Ammoniumacetate with various pH was used as a buffer to extract palladium from PdCl2·2H2O 0.1 mkg/ml solution. The main task for the use of inert organic compound in extraction is the selection of reagent which dissolves it but does not form any compound. With this aim the influence of different solvents on their reagent was researched. The experiments show that chloronaphthenic acid is dissolved well in organic solvents. Its solution, for example in kerosene, is light-resistant, does not hydrolyze in water, alkalis and acids. So, chloronaphthenic recomendefor palladium extraction
