METHOD FOR HETEROGENEOUS CATALYTIC DECOMPOSITION OF COMPLEXONS AND SURFACE-ACTIVE SUBSTANCES IN TECHNOLOGICAL SOLUTIONS OF RADIOCHEMICAL PRODUCTIONS ON NICKEL-FERRICYANIDE CATALYST Russian patent published in 2015 - IPC G21F9/04 C02F1/58 B01J23/755 B01J23/745 B01J27/26 B01J41/04 

FIELD: chemistry.

SUBSTANCE: invention relates to method for heterogeneous catalytic decomposition of complexons and surface-active substances in technological solutions of radiochemical productions on nickel-ferricyanide catalyst. Nickel ferricyanide, applied on anion-exchange resin, is applied as catalyst under impact of oxidative system, which consists of hydrogen peroxide and nitric acid, in dynamic mode in thermostatted apparatus of column type. Possibility of claimed method realisation is confirmed by researches on laboratory installation, shown on fig. 1, which includes: catalytic column with jacket (1), thermostat (2), peristaltic pump (3), reservoir with initial solution (4), receiving tank (5), measuring cylinder (6), V-01, V-02, V-03 are needle valves for consumption regulation.

EFFECT: method makes it possible to reach almost complete degree of decomposition and minimal residual concentrations by complexon and surface-active substance.
