흡착 교질 포말부선법에 의한 Cobalt Ion의 제거
Removal of Cobalt Ion by adsorbing Colloidal Flotation
초록
모의폐액으로 제조한 50ppm의 코발트이온을 Fe(III) 및 Al(III)의 응집제와 sodium lauryl sulfate의 계면활성제를 사용하여 흡착 교질 포말부선법으로 제거하였다. 용액의 pH, 계면활성제 농도, Fe(III) 및 Al(III) 농도, 공급기체의 유속 등을 변수로 하여 실험한 결과, Fe(III)를 응집제로 사용한 경우 초기 코발트이온농도 50ppm, pH 8.5, 공급기체유속
Simulated waste liquid containing 50 ppm cobalt ion was treated by adsorbing colloidal flotation using Fe(III) or Al(IlI) as flocclant and a sodium lamyl sulfate as a collector. Parameters such as pH, surfactant concentration, Fe(III) or Al(III) concentration, gas flow rate, etc., W앙e considered. The flotation with Fe(III) showed 99.8% removal efficiency of cohalt on the conditions of initial cobalt ion concentration 50 ppm, pH 9.5, gas flow rate 70 ml/min, and flotation time 30 min. When the waste solution, was treated with 35%
