METHOD OF PREPARING HETEROGENEOUS METAL-POLYMER CATALYST FOR CLEANING WASTE WATERS TO REMOVE PHENOL COMPOUNDS Russian patent published in 2008 - IPC B01J37/02 B01J23/40 C02F1/72 

FIELD: waste water treatment.

SUBSTANCE: method comprising deposition of active components onto polymer carrier followed by washing with modifying solution and drying of resulting catalyst is characterized by that above-mentioned polymer carrier is a super-crosslinked polystyrene preliminarily washed with acetone and dried, deposition of active components onto polymer carrier is accomplished by impregnating it for 8-10 min with complex solution of platinum group metal chloride and/or gold-hydrochloric acid sodium salt in concentration 0.57-64.5 g/L in complex organo-alcohol-water solvent containing, in particular, tetrahydrofurane, methanol, and water, whereupon catalyst id dried to constant weight and then optionally washed with modifying solution of sodium carbonate, 2.76-136.74 g/L, and with distilled water to neutral pH = 6.8-7.2. Catalyst allows deep oxidation of phenol compounds at high degree of conversion.

EFFECT: enhanced phenol oxidation activity of catalyst, simplified catalyst preparation technology needing utilization of lesser amounts of expensive chemicals.
