Nanoclay-based nanoadsorbents for wastewater treatment

The majority of human activities produce some sort of waste, and these wastes often end up in wastewater treatment plants, therefore, resulting in wastewater containing undesirable and contaminating chemicals. As the standard of living improves, these contaminants become more diverse. This results in conventional treatment methods being less effective in protecting water resources from contaminated effluents. Thus there has been a surge in the exploration of new-generation wastewater treatment technologies. Within these, adsorption onto nanoclays has been suggested by various researchers. In this chapter, the different types of nanoclay-based nanoadsorbents reported in the literature have been reviewed with the aim of highlighting their applicability in wastewater treatment.
