Аннотация: Sorption recovery of palladium from nitric acid solutions on carbon adsorbents BAU, LKAU-7, ABG and UC has been investigated using model solutions with concentrations 8 x 10(-4)-8 x 10(-3) mol/l for palladium and 1, 2 and 5 mol/l for nitric acid. The recovery degrees of Pd(II) depend on the concentration of palladium in contacting Показать полностьюsolutions as well as on the type of sorbent used. On average, they reach 60%-100% with the maximum in 1 M HNO3 The palladium desorption by 10% thiocarbamide solution in 1M H2SO4 proceeds completely for the sorbent LKAU-7. The use of thiocarbamide solutions in 0.1 M NaOH increases the desorption of palladium from the sorbents BAU and UC up to 80%-85%.
