Abstract
The effect of alginic acid, extracted from the Lessonia trabeculata calcareous marine algae, was studied in the electrocrystallization of calcium carbonate ( CaCO 3 ) on indium tin oxide (ITO) transparent electrodes. Scanning electron microscopy, X-ray diffraction-collected data and microscopic observations show that the presence of Mg 2 + at the electrolyte induces the magnesium calcite and aragonite phase formation along with the changes in morphology and crystal orientation. Addition of alginic acid strongly inhibits the effect of Mg 2 + on the crystallization, receiving in favor of the nucleation and growth of calcite phase of CaCO 3 . These results suggest that the alginic acid acts as an organic template in the electrocrystallization of CaCO 3 , controlling the crystallographic orientation of crystal growth, and as a consequence, the crystal morphology.
