nr 2

New sorbents capable of forming hydrogen and it-jt bonds with phenols were prepared. These sorbents possess aromatic Tt-acceptor residues and hydrogen donor and acceptor sites. The surroundings of the sites are of different polarities. Sorption efficiency of these materials was studied by reversed-phase high performance liquid chromatography. The testing mixtures consisted of three phenols of different polarity and acidity.

nr 6

The concentrations of chromium, nickel, copper, manganese, zinc, iron, cobalt and aluminum ions in drinking waters from eight sites of Tokat, Turkey, were determined by atomic absorption spectrometry. The values found the present work for the heavy metal contents of the drinking water samples of Tokat, Turkey were below the maximum tolerable limits set by the World Health Organisation (WHO) and the Water Pollution Control Regulation of the Turkish authorities.
