Abstract
Tromethamol-modified siloxane surfactants (disiloxane and siloxane copolymers), which have previously been synthesized in the authors research group, were reacted with metal salts (Cu(II)acetate, Zn(II)acetate and Fe(III)sulfate). The obtained compounds were characterized by FT-IR and 1H-NMR spectroscopy. The evolution of the reactions was followed by UV-Vis spectra and the obtained data proved the afinity of the tromethamol-based siloxane compounds towards metal species. The formed Cu complexes showed significantly higher electronic absorption compared to Cu(II)acetate. The tested siloxane surfactants, which also act as chelating agents, could be used for improving metal detection or in certain decontamination processes.
