These adsorbents have a fast adsorption rate and high adsorption efficiency, efficient to remove various pollutants and they are easy to recover and reuse. These features highlight the suitability of CNTs for the treatment of water polluted with heavy metal ions and dyes. This review outlines the preparation of CNTs as well as different methods of surface modification of these materials by non-covalent and covalent functionalization strategies. Additionally, an overview of recent developments and applications of CNTs for heavy metal ions and dyes pollutant removal is discussed in detail. Based on current research and existing materials, some new and futuristic approaches in this fascinating area are also discussed. The main objective of this review is to provide up-to-date information about the most important features of CNTs and to show their advantages as adsorbents in the treatment of polluted aqueous solutions.","PeriodicalId":14081,"journal":{"name":"international journal of nano dimension","volume":"1 1","pages":"109-120"},"PeriodicalIF":1.5,"publicationDate":"2016-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73277310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biological methods are the preferred to combat with the issues concerned with the nanoparticle synthesis. Within this decade, thousands of plants have been screened to analyze the final impact on characterization and morphology of AgNPs compared to general modes of their synthesis. Phytosynthetic method is an eco-friendly route that can lead to an advanced production of silver nanoparticles with controlled morphology.
