Cd and Pb represent a serious ecological problem due to their soluble nature, their mobility and ability to accumulate in the soil. The exposure to these heavy metals can originate from different sources (drinking water, food, air), and they can make

The study of the interaction of chromium with O-donor humic-like ligands is performed by electrospray-ionization mass spectrometry (ESI-MS) and ultraviolet/visible (UV/VIS) spectrophotometry. Heterogeneity of functional groups justifies the use of mo

UV-VIS spectrophotometric investigations of Cu(II) complexes with hydroge-nated dextran showed that the complexation of Cu(II)-ions began at pH > 7. The formation of Cu(II) complexes with dextran monomer units was observed at pH 7-12. With further in
