摘要
The chemical contamination of water from an extensive variety of toxic derivatives, specifically heavy metals, aromatic molecules and dyes, is a genuine ecological issue attributable to their potential human lethality. In this way, there is an earnest need to create advances that can remove harmful toxins found in wastewaters. Among all the reported treatment techniques, adsorption is one of the more prevalent systems for the removal of contaminations from the water. Adsorption is a standout among the most simple and effective strategy for treating industrial effluents, and a valuable device for ensuring nature. The increasing number of publications on adsorption of toxic compounds by modified bentonites demonstrates that there is a recent increasing interest in the synthesis of new low-cost adsorbents used in water treatment. The present review demonstrates the late advancements of nanotechnology in the synthesis of nanoadsorbents containing bentonite and its composites. The primary target of this review is to depict the adaptable way of bentonite and its composite and their capacity to absorb variety of inorganic contaminants, which are available in the water. It is evident from the review that modified bentonite composites (low-cost adsorbents) have demonstrated high removal capabilities for certain inorganic contaminants from water.
