dc.description.abstractCockle shell has been usually used as craft materials, while the rest was discarded as waste. This shell contains 97% of CaCO3, which recognized as an adsorbent in the ash form. This ash was produced via calcination step at 800ÂșC for variation time of 4, 5, and 6 hours. Each of the ash obtained were tested for the ability adsorption of through the Cu2+, Sn2+, CN- and NO3 - ions with a concentration of 50 ppm and contacting for 24 hours. The ash blood cockle shells was potential as an adsorbent cations such as Cu2+ ions (98.92%) and Sn2+ ions (98.11%) that were analyzed using Atomic Absorption Spectrophotometer (AAS), and anions such as CN- ions (57.54%) and NO3 - ions (64.41%) that were analyzed using a UV-Vis spectrophotometer.en_US
