Zusammenfassung:It has been found that catalytic reactions used for determination of microquantities of cobalt ions and metals of platinum group can occur on the surface of hard carriers. For carrying out of catalytic reactions on surface hard carriers were chosen and ways of its preparing were developed. It was proposed some materials that may serve as carrier for catalytic reactions and means of their modification. It was shown that interaction between components of catalytic reactions and carrier surface depends on nature of hard carrier, notably: absence of interaction (hydrophobic polymers), irreversible sorption (gels of metal oxides), active interaction with surface functional groups (different kinds of paper). Dependences between speed of catalytic reactions taken place on surface of hard carriers and catalyst concentrations in solutions have been found. It may serve as a basis for working of sorption-catalytic test-methods for revealing and semiquantitative determination of microquantities of cobalt ions and metals of platinum group.
