- Heavy metal contamination, especially from cadmium (II) ions, poses a major environmental threat, particularly in developing countries.
- This study investigates the use of a composite film made from starch, eggshell, and orange peel-activated carbon to effectively remove cadmium from water, utilizing advanced characterization techniques like X-ray diffraction and scanning electron microscopy.
- The findings show that the composite film exhibits a highly porous structure, achieving nearly complete cadmium removal (100% at 0.5 mg/L and 99.7% at 1.0 mg/L), suggesting its potential as a cost-effective adsorbent for environmental cleanup.
In the current study, cornstarch (CS) and eggshell powder (ESP) were combined using a casting technique to develop a biodegradable film that was further morphologically and physicochemically characterized using standard methods. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were used to characterize the morphology of the ESP/CS film, and the surface of the film was found to have a smooth structure with no cracks, a spherical and porous irregular shape, and visible phase separation, which explains their large surface area. In addition, the energy dispersive X-ray (EDX) analysis indicated that the ESP particles were made of calcium carbonate and the ESP contained carbon in the graphite form.

Hence, our study developed and characterized a biopolymer film based on starch and anthocyanin for prospective meat freshness monitoring applications. The developed film was morphologically characterized using different morphology instruments to identify the interaction between anthocyanin and starch.
