The adsorbing colloid flotation of Pb(II), Cd(II), and Cu(II) with ferric hydroxide floc and the mixed surfactant system sodium dodecylphosphate (SDP)/n-hexanol was investigated. Good removals of Pb and Cu were obtained; removal of Cd was less satisfactory. The effects of interfering anions (sulfate, oxalate, silicate, phosphate) were studied; higher concentrations of these ions could be tolerated with SDP/n-hexanol than with sodium dodecylsulfate. Measurements of the cmc of SDP were made; low solubility prevented determinations in the pH range 4-8.5.
