FIELD: chemical technology, processes of recovery of slime containing metals of platinum group. SUBSTANCE: the offered method provides for recovery of metals of platinum group internal surfaces of units using catalysts based on platinoids and includes treatment of these surface with aqueous solution of absorbent by circulation of aqueous solution at velocity head in zone of action within 10-5-20 Pa with subsequent recovery of separated slime by means of filtration. EFFECT: higher efficiency. 3 cl, 2 tbl
