In the paper preparation, characteristics and potential applications of two new sorbents with chemically bonded transition metal complexes have been presented. The sorbents have been synthesized by attaching copper (II) chlorides to the silica surface through ketoimine groups. The suggested application area of the proposed sorbents is related with solid-phase extraction (SPE) of aromatic compounds of different structure, e.g., phenol, 2-chlorophenol, and benzene from water matrix. The experiments proved high efficiency of the sorbents, the ranging recovery rates from 88% to 96% and the LOD values from 0.2 for phenol, and 1.0 for o-chlorophenol.Basic characteristics of the sorbents synthesized were determined by the use of elemental analysis and UV-VIS spectroscopy.

Concern for the natural environment increasingly devotes more attention to growing potential hazards resulting from the release of various substances. Currently, one of the main problems associated with environmental pollution is the derivation of organic compounds from wastewater. Substances derived from sewage leaks into the environment in the form of a multicomponent mixtures often enhances the toxic effects caused by these compounds. While analyzing the reports in the literature of the last two decades it can be seen that substantial efforts are devoted to the determination of selected trace contaminants present in wastewater. Among the most marked there are endocrine disrupting compounds, residues of pharmaceuticals and personal care products, plastics and sunscreens. Recently, a new group of compounds joined the aforementioned contaminants, namely drugs, whose legality and availability is increasing every year. Exposure to these type of compounds, named in the literature as emerging contaminants (ECs), involves, among others, such effects as hormonal imbalance, reduction of the survivability of aquatic organisms and reproductive problems. This paper provides a review of the types of emerging organic groundwater contaminants (EGCs) which are beginning to be found in the natural environment in many countries all around the world.
