It has been particularly interesting to develop an adsorbent demonstrating a high adsorption capacity and low cost for removing various pollutants from contaminated waters. Inorganic chemical adsorbents have thus been studied widely, aiming at providing an alternative to the activated carbon in the treatment of surface and ground water and industrial effluents. This article aims to review and provide new insight into the recent development of modified clays, zeolites and layered double hydroxides based sorbents for the removal of aqueous contaminants such as heavy metals, natural and synthetic organic matter and anion contaminants. A new type of sorbent, metal-organic frameworks (MOFs), is also introduced owing to its extremely high surface areas and promising adsorption capacity in treating emerging organic micro-pollutants.
