Characterization of nano calcium powder from blood cockle ( Anadara sp.) shell produced by using different hydrochloric acid concentration

[摘要] Blood cockles one of shellfish which can potentially be developed as a source of protein and minerals. The shell provides a source of calcium, as the structure is similar to that of bone. This research aims to characterize nano calcium powder from blood cockle ( Anadara sp.) shell produced by using different hydrochloric acid (HCl) concentrations. Four concentrations vis. 0.5 N, 1.0 N, 1.5 N and 2.0 N were designed by using a completely randomized design. This research revealed that different the concentration affected the particle size and mineral content of the nano calcium powder, where concentration of 1 N was the most appropriate concentration used. The yield generated was 0.82% with the calcium content of 62.89%, the particle size of 454.4nm and high uniformity.
