Nano-adsorbents have gained special attention in water pollution mitigation in India since last decade. Two vital properties make nanoparticles highly lucrative as adsorbents. On a mass basis, nano-particles have much larger surface areas compared to macro particles. They can also be enhanced with various reactor groups to increase their chemical affinity towards target compounds. Nano-adsorption techniques are now widely used to remove cations, natural organic matter, biological contaminants, inorganic pollutants, nitrates and arsenic from groundwater, surface water and industrial effluents. Nano-adsorbents of mixed oxides such as iron-cerium, iron–manganese, iron-zirconium, iron-titanium, iron-chromium, cerium-manganese were successfully employed for water treatment. Among the available different technologies, adsorption is one of the best due to its easy handling, low cost and high efficiency. The environmental fate and toxicity of a material are critical issues in materials selection and design for wastewater purification system. The success of the nanotechnology in field conditions is a factor of interdisciplinary works, which need successful collaboration of chemistry, material science and geology and biosciences.
