In this study, the influence of acid solutions on the production of precipitated calcium carbonate (PCC) using seashells was investigated. In terms of the Ca dissolution efficiency and atmosphere for dissolving CO 3 2−, the results indicate that HCl, HNO 3, CH 3 COOH, and HCOOH at 1.0 M were the most ideal among the acid solutions. The use of weak …

This study aimed to prepare precipitated calcium carbonate (PCC) from pearl oyster shells by dissolving with HNO 3 solution, carbonation with carbon dioxide, and sonication. Shells with a size of 200 mesh were calcined at 900 ºC for 3 hours, dissolved in 0.8 M nitric acid solution and added ammonia to form an alkaline medium.
