| dc.description.abstract | Snail shells (Pomacea canaliculata) are usually used only as craft material its alternative utilization is used asan adsorbent. CaO is a chemical compound whose structure is a hexagonal cube with an open frame on the cubic lattice where van der Walls bonds can occur, so that shell ash can be used as an adsorbent. CaO which is obtained from the calcination is carried out at temperature of 800 oC for ±10 hours. The ability of the adsorbent was tested against variation of copper in a solution with the variation of copperion concentration, activator Na2CO3 and contact time. From the research result of the ash of snail shell it was obtained that CaO content is 92,29%. The optimal absorption was obtained at 20 hours of contact time and 10% Na2CO3 concentration at 50 ppm copper solution with the adsorption of 1,9997 mg/g and the adsorption efficiency was 99,9876%. | en_US |
