Abstract

The ever-increase in water pollution by industrial and anthropogenic activities is a well-established risk to the well-being of the human populace. Several remediation systems and processes have been and are currently used to tackle the challenge. Scientists have risen to the challenge and are thus synthesizing various compounds/composites to serve as water remediators from pollutants, especially via sorption processes. In this short review, the potential of some composites; (Polyaniline (PANI), Titanium Dioxide (TiO2), and Bentonite) in wastewater treatment is briefly discussed. The combination of the three composites is anticipated to be an excellent nanocomposite in wastewater remediation due to their excellent adsorptive properties, ease of preparation, and environmental benignity.
