초록
폐기물로 대량 발생되는 굴껍질을 활용한 vaterite 형 탄산칼슘 제조 실험을 하였다. 굴껍질을 800 °C 의 온도에서 항량이 되도록 가열하여 산화칼슘이 주성분인 소성 굴껍질을 제조하였다. 이 굴껍질을 질산 용액에 녹여 0.1M 질산칼슘 수용액을 만들고, 0.1 몰 라이신/1 몰 생석회가 첨가된 0.1 M 탄산나트륨 수용액과 20 °C, 600 rpm 교반 조건에서 1시간동안 반응시켜 탄산칼슘을 제조하였다. XRD, SEM, Size 분석을 하고 vaterite 84.5%, calcite 15.5% 함유한 구형 탄산칼슘을 확인하였다. 평균 입경 범위는 6.87 μm 이었고, 아미노산 분석에서 탄산칼슘 내의 라이신 함유량은 0.1%이었다.
The experiments to produce the vaterite type calcium carbonate were conducted for using the waste oyster shell as the recycling resources. Firstly, the oyster shell were calcinated at 800 °Cfor 24 h. Calcinated oyster shell were reacted with the nitric acid solution, and were diluted to 0.1 M Ca(NO3)2 solution. This solution was mixed with 0.1 M Na2CO3 contained 0.1 mol lysine/1 mol CaO at 20 °C and 600 rpm mixing condition for 1 h. The reaction products were identified to vaterite type calcium carbonate (84.5% vaterite, 15.5% calcite) by XRD and SEM analysis. Mean particle diameter was 6.87 μm, and the lysine content in calcium carbonate was analyzed to 0.1%.
