Abstract
Heavy metals from households and industrialization discharge into coastal and marine ecosystems could threaten living organisms. Hence, control of heavy metals from the environment should be done. The application of waste seashells as adsorbent for heavy metal has received growing interest due to having porous surface structure, abundance availability, eco-friendliness, and low cost. Instead of being dumped, which can lead to environmental pollution, this study aims to use green mussel (Perna viridis) and blood cockle (Anadara granosa) shells as adsorbents for Cr(VI) ion. Blood cockle and green mussel shells were cleaned, then milled into powder (150 μm), semi-rough fragment (45 μm), and rough fragment (2 mm). The concentration of Cr(VI) ion in the samples was determined by AAS method. The shell was characterized by scanning electron microscopy (SEM). The result shows that the amount of ion Cr(VI) adsorped increased with decreasing particle size of the adsorbent, and the maximum amount of adsorption was obtained by Anadara granosa (65,767%) rather than by Perna viridis (58,073%). According to these results, the shells of both Anadara granosa and Perna viridis could be used as effective adsorbent for chromium. More research is needed to apply this method effectively in conjunction with the study.
