ZoP Remediation of Heavy Metal Ions in synthetic contaminated effluent by Calcium Carbonate from Asiatic Clams “Tulya” (Corbicula fluminea) shells

autorzy: Jerome A. Sombilon Anna Beatriz A. Suavengco

The study aimed to investigate if the Asiatic Clams (Corbicula fluminea) can be a good adsorbent in the remediation for water contaminated by Cadmium (Cd) and Lead (Pb). A test was carried out by determining the chemical components present in the clams. The clams were crushed then sun dried. Granulized samples were analyzed under FTIR showing the presence of Calcium carbonate. In two different columns containing granulized clams, lead and cadmium samples were passed through. Heavy metals that passed through were analyzed in an AAS machine with the following results: Cadmium got a removal percentage of 97.37% (Cd1), 98.33% (Cd2), and 98.40% (Cd3) and Lead got 97.68% (Pb1), 98% (Pb2), and 98.16% (Pb3). It can be concluded that the Asiatic Clams can absorb the Cd and Pb; thus making it a good remedy for contaminated water.
