Abstract
The scarcity of clean water and increasing water pollution caused by domestic and industrial activities have encouraged the development of adsorbent materials that are effective, economical, and environmentally friendly. Eggshells are an abundant waste material and contain approximately 94–95% calcium carbonate (CaCO₃), making them a potential source of calcium for the synthesis of inorganic materials. This study aimed to synthesize **calcium peroxide (CaO₂)** from eggshell waste, investigate the effects of eggshell type and drying temperature on the characteristics of CaO₂, and evaluate its effectiveness as an adsorbent for acetic acid. The synthesis was carried out through eggshell preparation and calcination at 900°C to produce CaO, followed by hydration to form Ca(OH)₂ and precipitation using H₂O₂ to produce CaO₂. The eggshell types used included commercial chicken, native chicken, quail, and duck eggshells, while the CaO₂ drying temperatures were varied at 60, 70, 80, 90, and 100°C. Material characterization was performed using **X-Ray Diffraction (XRD)** and a **Surface Area Analyzer (SAA)**, while adsorption performance was determined based on the adsorption capacity and acetic acid removal percentage. The results showed that the synthesis successfully produced a crystalline CaO₂ phase with crystallite sizes ranging from **15–28 nm**, although a small amount of CaCO₃ residue remained due to recarbonation. The type of eggshell affected the characteristics of the synthesized material, with the highest surface area obtained from CaO₂ derived from native chicken eggshells, reaching **19.667 m²/g**. The optimum adsorption performance was obtained at a drying temperature of **80°C** using native chicken eggshells, with an adsorption capacity of **347.54 mg/g** and a removal efficiency of **34.75%**. These results demonstrate that eggshell waste has the potential to be utilized as a sustainable raw material for the synthesis of CaO₂, which can be used as an adsorbent material.
