Abstract

The removal of copper ion from aqueous solution by adsorption with bone char that made from spent pig bone has been studied. This paper was studied the effects of bone char dosage and pH. The optimal results show that bone char adsorbs about 96.5 percent of copper ion in aqueous solution containing 50 mg/L as initial concentration at pH 5.0 when the bone char of 5g/L is used for 30 hours. Increase in the initial pH of the copper solution resulted in an increase in the copper ion uptake per weight of the sorbent Freundlich isotherm model was found to be applicable for the experimental data of $Cu^{2+}$.

폐기되는 돼지 뼈로 제조한 bone char를 이용하여 용액 중에 존재하는 구리이온 제거를 검토하였다. 이 논문은 구리이온 농도가 50mg/L 인 시료 용액에 흡착제로 bone char를 1, 3, 5, 7, 10, 15g/L 첨가하여 실험한 결과 흡착제 첨가량은 5g/L가 적합하였고 30 시간 처리하였을 경우 구리이온 제거효율은 96.5% 이었으므로 반응시간은 30 시간 이상이 효과적이었다. 구리이온 수용액의 초기 pH 증가는 흡착제 무게당 구리이온 흡착량이 증가하였다. 구리 이온의 흡착 실험자료는 Freundlich 등온식 모델에 잘 일치하였다.
