    The influence of different methods of pre-modification (thermal, hydrothermal, and acid-thermal) of natural bentonite on the catalytic activity of bentonite-anchored palladium(II) and copper(II) complexes in lowtemperature oxidation of carbon monoxide has been studied. The contributions of weakly and strongly bound Pd(II) and Cu(II) forms to the total activity of the catalysts were evaluated by two methods, desorption of the metal ions and a kinetic method.

    Some features of Pd(II) and Cu(II) adsorption with bentonites and activity of bentonite based catalysts in the reaction of carbon monoxide oxidation
    (2016) Rakitskaya, Tatiana L.; Vasylechko, V. O.; Kiose, Tetiana O.; Dzhyga, Ganna M.; Gryshchouk, Galyna V.; Volkova, V. Y.; Джига, Ганна Михайлівна; Джига, Анна Михайловна; Кіосе, Тетяна Олександрівна; Киосе, Татьяна Александровна; Ракитська, Тетяна Леонідівна; Ракитская, Татьяна Леонидовна
    For the first time, Ukrainian natural bentonites are used as supports for anchoring Pd(II) and Cu(II) complexes. Depending on the bentonite origin, such supported metal complexes have different catalytic properties in the reaction o f carbon monoxide oxidation. Bentonites, similarly to other natural sorbents, are selective with respect to metal ions: the bentonite origin affects Cu(II) position in the selectivity orders. However, there are no data concerning adsorption o f Pd(II) and also Cu(II) and Pd(II) when they are simultaneously present in aqueous solution used for bentonite impregnation.
