Hybrids of layered double hydroxide (LDH) are emerging as robust adsorbent materials for the removal of toxic organic dyes from wastewater. The LDH-containing hybrids have shown excellent adsorption performance owing to their large surface area and chemical stability. These hybrids are non-toxic, cost-effective, and readily available and can easily be regenerated. Herein, this review aims to summarize the recent progress of LDH-containing hybrids as highly efficient adsorbents for dye removal from aqueous phase. The study discusses various important parameters such as adsorption capacity, surface area, toxicity, and regeneration ability. The effect of adsorption variables such as temperature, adsorbent dosage, pH and contact time has also been briefly reviewed. Moreover, the article also provides insight into adsorption mechanisms and adsorption kinetics. (C) 2019 Elsevier B.V. All tights reserved.
