Synthesis and Dehumidification Performance of Calcium Chloride Derived from the Waste Shells of Anadara granosa

Abstract:

The waste shell of Anadara granosa or blood cockle is utilized as an alternative source for calcium carbonate (CaCO₃) in the synthesis of calcium chloride (CaCl₂) as a dehumidifier. In this paper, the synthesis of CaCl₂ from the waste shell was investigated at various concentrations of HCl reactant and the shells’ particle sizes to determine the optimum yield. The synthesized CaCl₂ was further tested on its capacity in adsorbing moisture and compared with the commercially-available dehumidifier. It was found that concentration of HCl at 5 M produced the highest yield, while the particle size of 0.5 mm took the shortest period in producing CaCl₂ from the waste shells of Anadara granosa. Investigating the performance as dehumidifier in a controlled environment, synthesized CaCl₂ showed similar capacity in sorbing moisture as the commercially-available dehumidifier, proving the high potential of the waste shells of Anadara granosa to serve as a green alternative for CaCO₃ in producing CaCl₂.
