Abstract
Sorption of platinum chloro complexes from solutions with the help of oxidized carbon sorbents was studied. An effect of the oxygenated surface functional groups of oxidized carbon sorbents on their sorption capacity was studied using IR spectroscopy, pH-metry, titrimetry. Sorption isotherms for H2PtCl6 and Н2PtCl4 were obtained. It was established that the capacity of the sorbent with respect to H2PtCl6 increased by a factor of 2.4.
