Abstract:The calcium-alginate-silica demonstrates the potential application of a membrane for clean water supply through the absorption of Cl- and Na+ ions. Calcium originated from coral skeletons, while silica was extracted from the beach sands of The Gulf of Prigi. The produced membrane was characterized using XRF, FTIR, and SEM techniques, followed by NaCl solution adsorption studies. The results show that the coral skeletons as source of Ca consist mainly of calcium oxide based on XRF analysis, ranging from 90.86% … Show more
