摘要: AbstractThe effect of surfactants nonylphenolpolyethylene glycol (D1), dinaphthylmethane-4,4′- disulphonic acid (D2) and polyethylene with a molecular weight 400 (D3) added separately or as mixture (D1+D2+D3) on Co-Zn dust cementation kinetics morphology obtained deposits was investigated in the presence both Cu Sb. The rate constant Sb 3 to 5 times lower than that found up higher This indicates high inhibition Co cementation. D1, D3 D1+D2+D3 inhibit highest D1. A decrease concentration from 200 35 mg dm-3 at increased by despite D1+D2+D3. An increase substantially decreased crystallite size deposit porosity.On investigue l’effet des agents nonylphenolpolyethylen...
