다국어 초록 (Multilingual Abstract)
The characteristics of the bubble adsorptive separation of CTAB(cetyltrimethylammonium bromide) and CuS precipitates was investigated. The Langmuir adsorption equation was adequate at very low concentration of CTAB, and the adsorption heat was determined from the batch analysis considering the bulk liquid accompanied between bubbles. The adsorption mechanism was explained with the collision adsorption between bubbles and precipitate particles. The optimum concentration ratio of [CTAB] to [CuS] for adsorptive separation was 0.1 and coincided with the ratio for the coagulation of particles. The collection efficiency was depended on pH and CTAB concentration but independent of the air flow rate, and the maximum efficiency was 0.0002. The selective separation of ZnS from the mixture of Cu-Cd-Zn sulfides was obtained by the bubble adsorption with CTAB.
