Results of research on removal of lead from synthetic and industrial Cu-Pb-Fe alloy with argon barbotage are presented. For examinations was taken a synthetic alloy and industrial alloy coming “Glogow II” Copperworks. As basic research equipment was used a pipe resistance furnace enabling heating of samples up to 1 473 K. Examinations were made in 2 test series. The 1 series was performed on the synthetic alloy, while in 2 series was used an industrial alloy. All series were conducted at 1 473 K and with gas flow 5,55•10-6, 6,94•10-6, 8,33•10-6, 9,72•10-6 m3•s-1.Daju se rezultati istraživanja odstranjivanja olova iz sintetičke i industrijske Cu-Pb-Fe legure argonskim pročišćavanjem. Za ispitiva nje odabrana je sintetička industrijska legura iz tvrtke za bakar “Glogow II”. Osnovni uređaj za istraživanje je cje vasta peć sa mogućnošću zagrijavanja uzoraka iznad 1 473 K. Ispitivanja su provedena u 2 serije. Prva serija je provedena na sintetičkoj leguri, a druga serija na industrijskim legurama. Sve serije su izvedene na 1 473 K sa strujom plina 5,55•10-6, 6,94•10-6, 8,33•10-6, 9,72•10-6 m3•s-1
