| 제목 | A Study on the Extraction of Calcium Ion from Oyster Shell |
| 초록 | Annual oyster shell generation in Korea is 300,000 tons, and efforts to recycle it have continued steadily. However, despite the increased recycling rate of oyster shells, large amounts of them have been left unattended. In this study, and experiment was conducted to verify the basic properties of oyster shell for the purpose of synthesizing high value-added materials using oyster shell. Using eluents such as HCl, CH3COOH, NH4Cl, etc., calcium ion dissolution conditions in oyster shell were confirmed. The characteristic analysis was conducted using XRD, XRF, and ICP-AES. In addition, various variables such as solid-liquid ratio of shell and eluent, particle size and dissolution time were reviewed and change in the properties of precipitates were compared according to pH of the eluent after the reaction. |
