Overview of the Surface Adsorption of Common Dyestuffs Used in the Textile Industry onto Granulated “Green” Materials

The contamination of water sources via the release of chemical dyestuffs used in textile manufacturing has become a source of concern for environmental scientists in recent years. Furthermore, the accumulation of heavy metals and organic compounds used in the dying process present adverse effects towards natural biodiversity (plant, aquatic, and marine life), as well as negative effects on human health. Attempts to remediate and further prevent these contaminants from polluting public waterways using adsorption-based removal processes are currently in place. However, those processes typically use expensive and/or ecologically unfriendly settings. Thus, the search for “greener” adsorbents, such as crushed eggshells, is of paramount importance.
