The solution is to remove anrecovering palladium from waste and hydrogenationnvfld, containing 2 to 25 µg / mlnpalladium. The essence of the solution is thatnthat a macroporous absorbent is usednamidooxide polystyrene-type polymernfunctional group, with absorptionnrun at pH 1 to 6.5, waste ratenwater of 0.3 to 2.5 m / h and trapped palladiumnis obtained from the absorbent by burning,nrespectively. by extraction with strong mineral acids.nThe absorbent may be a polymernwith added charcoal, 'orn% of asbestos in an amount of 5 to 15 wt. relativento the weight of the polymern1 to 5 wt. oxidizer,nas nitric acid, organic peracidsnas peroxy, permectic, formaldehyde. |
