dc.description.abstractThis work aimed to synthesize and characterize the calcium acetate monohydrate (Ca(CH<inf>3</inf>COO)<inf>2</inf>·H<inf>2</inf>O) from the exothermic reaction between CaCO<inf>3</inf> powder derived from cockle shells with three different acetic acids (8, 10, and 12 mol L<sup>−1</sup>) concentrations by the rapid and easy process without pH and temperature control to lead to cheap chemical production. The physicochemical characteristics of all synthesized Ca(CH<inf>3</inf>COO)<inf>2</inf>·H<inf>2</inf>O samples are investigated based on the chemical compositions, crystal structures, vibrational characteristics, morphologies, and thermal behavior to confirm the target compound. A suitable concentration of 10 mol L<sup>−1</sup> CH<inf>3</inf>COOH was chosen to produce Ca(CH<inf>3</inf>COO)<inf>2</inf>·H<inf>2</inf>O with the highest yield (96.30 %), maximum calcium content (96.2 % CaO) with lower impurities, and time consumption of 17 h. The calcium acetate product obtained from cockle shells in this work shows differences in thermal stability, morphological structure purity, %yield, and metal contamination with those reported obtained from other sources and another shell type in the previous work. This research investigates the transformation of cockle shell waste into CaCO<inf>3</inf> for the production of calcium acetate, aiming to address environmental sustainability concerns by reducing the use of calcium ore resources and greenhouse gas emissions.
