초록

CTAB에 의한 CuS 침전 미립자의 응집과 기포 흡착특성을 고찰하였다. CTAB의 기포흡착은 Langmuir흡착식을 따르며, 포말간 본체액의 동반을 고려한 회분해석으로부터 구한 흡착열은 3700cal/mol로 나타났다. CTAB에 의한 CuS미립자의 기포흡착은 기포-입자간 충돌흡착으로 설명되었고, 흡착분리에 대한 최적 농도비는 CuS의 최적 응집농도비와 일치하였으며, 그 값은 [CTAB] 대 [CuS]가 0.1로 얻어졌다. 기포에 의한 포집효율은 pH와 CTAB농도 등에 의존하나 공기의 유량에는 무관하였으며, 최대 포집효율은 최적 첨가농도에서 0.0002로 나타났다. 또한 Cu-Cd-Zn 황화물의 혼합계에서 CTAB를 사용한 기포흡착의 경우 ZnS의 선택적 분리가 가능하였다.

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.
