Abstract:


Background: The huge quantity of wastewater, containing poisonous and hazardous dyes, is released by various industries which pollute water at resources in a direct and indirect way. Most of dyes are dangerous class of water contaminants have affected environment drastically. Some dyes such as Congo red, Rhodamine B, Methylene blue, Methyl violet, and Crystal violet etc. are a serious anxiety for human being.

Remediation Methods: Numerous methods are available for removal of dyes from water. The adsorption, being superior and ecofriendly technique, has advantages for eliminating organic dyes because of availability of materials as adsorbents. The inexpensive nanomaterials is more attractive choice for remediation of various dyes, due to their unique properties and afford the adequate pathway to absorb any organic dye from water to overcome their hazardous effects on human health.

Results: In this review, we have discussed latest literature related to various types of synthesis, characterization and uses as adsorbent for highly adsorptive removal capacity of nanoparticles for organic dyes.

Conclusion: Adsorption technology provides an attractive pathway for further research and improvement in more efficient nanoparticles, with higher adsorption capacity, for numerous dyes for eliminating the dyes discharged from various industries and thus can reduce the contamination of water. Therefore, nanocomposites may contribute for future prospective water treatment process.
