| چکیده مقاله |
| Due to various pollutions, Wastewater treatment is one of the issues that required much attention. Dyes, as cationic and anionic dyes, are the main threaten in wastewater. In different studies; various adsorbents have been used to adsorb the dyes with the highest percentage. Carbon based and polymeric Nano materials are two kinds of dye adsorbents, which can adsorb the different dyes efficiently. Carbon Nano tubes (CNTs) and graphene oxide (GO) are known as carbon based Nano materials. As results show; carbon based materials are the best for adsorption of cationic dyes. The polymeric Nano materials, which involved Ion exchange resin, Nano magnetic polymers (NMP) and Extracellular polymeric substances (EPS). As the researches show, adsorptions which are based on polymeric nanomaterial are the best adsorption of anionic dyes. Also; the studies about isothermal models are so important for different kinds of dye adsorbents. It was found that the adsorption equilibrium data of cationic and anionic dyes were well defined with the Langmuir model. |
