Review on Silver Nanoparticles in Dye Effluent Treatment
Author(s): Vikram Mor*, Gopal Arora and Mohinder Pal
The present condition of water resources demonstrated the predominance of effluent drainage-related pollution. Contaminated rivers pose significant economic and environmental concerns, requiring the creation of a realistic solution to deal with the repercussions. Physical and chemical treatment techniques for indigo effluent cleansing presently are in use time-consuming, expensive, or unsuccessful. Due to their better interface surface chemistry sensitivity, nanoparticles are emerged as a preferable alternative for degradation and decolorization. In this regard, the use of metal nanoparticles in treating wastewater has been widely studied. Efforts were undertaken to discover the kinematics and statistics optimisation of the treatment parameters in order to effectively remove dyes. In addition, the usage of gold Nano composites has been shown to be effective. In contrast, studies have revealed the mechanisms of gold Nanomaterials toxicity, at even small doses, and also their harmful biological problems when contained in treated water. As a consequence, the providence of Ag nanoparticles free in processed wastewaters, which could pollute underground water, aquatic environments and soil, is an important worry. The present state of information on the utilization of Ag nanoparticles and silver-based Nano composites in wastewater, as well as current findings on argent Nanomaterials toxicity decrease, is covered in this review.
