Functionalized multi-walled carbon nanotubes for oil spill cleanup from water

Abstract The growing global economy resulted in an incessant increase transportation and exploitation of oil. Hence, the oil spillage has been considered a serious threat to aquatic terrestrial ecosystems. Therefore, water purification major challenge around world. There are numerous classical methods available for removal from water, but owing multiple defects disadvantages, research efforts have focused find such adsorbents which can improve adsorption capability. Traditional adsorbent material typically applied includes activated carbon, organoclays, wool, zeolites, etc. These materials suffer several drawbacks as low absorption capacity, non-selective absorption, complicated reusability, whereas nano-adsorbents offer advantages having sorption sites, large surface area, short intra-particle diffusion distance, tuneable pore size, ease low-temperature modification. Multi-walled carbon nanotubes (MWCNTs) extensively used with strong affinity organic pollutants. functionalization MWCNTs further capacity manifolds remove materials. nanocomposites also compatible green environmentally friendly adsorbents. This review paper aims at providing insight understand properties their potential use adsorb hydrocarbons water. Moreover, synthesis those materials, modification procedures including metal oxide nanoparticles, applications discussed detail. Graphic abstract
