Abstract: At present due to the shortage of water resources, effective treatment of wastewater is a foremost requirement and the treated water is using for gardening as well as agricultural purpose to avoid surface water utilization. In this aspect, the requirement is to develop and implement progressive wastewater treatment technologies with high effectiveness and less investment. Through point and non-point sources, the discharged water is obtained after utilizing domestic and industrial purposes and including storm water runoff. This wastewater containing different types of pollutants including heavy metal ions. These heavy metal ions are considered as the serious environmental problem in society. Methods are available to remove the pollutants from wastewater and among adsorption is a widely used method for the removal of pollutants and particularly it plays an important role in wastewater treatment for the removal of heavy metals. At present in the water purification research under Nanotechnology, Nano materials are used as adsorbents for removal of pollutants from wastewater. A number of researches have evidenced that Nano materials (Nano carbon materials, Nano metal particles, and Polymer based Nano particles) are the good adsorbents for the removal of heavy metal ions from wastewater due to their unique structural properties. Due to simplicity, less cost, easy handling, and efficiency, the adsorption process is commonly popular for removal of heavy metals. In this paper concentrated on a brief review on the availability of Nano metal oxide based adsorbents for removal of water pollutants.

I. INTRODUCTION

Water is nature’s most common, abundant and widespread chemical compound of all living creatures and we all ways thought to be available in sufficiently and a free gift of nature. Clean, safe and adequate fresh water is vital to the survival of human beings. Assurance of drinking-water safety is a foundation for the prevention and control of waterborne diseases.
