Nature meets innovation: Green synthesis of nanoparticles using plant extracts and ionic liquids for a sustainable future

Title : Nature meets innovation: Green synthesis of nanoparticles using plant extracts and ionic liquids for a sustainable future

Abstract:

Green synthesis of nanoparticles (NPs) is an emergent study field in nanotechnology as this process is nonhazardous, green, effective, and inexpensive when compared to other traditional physical and chemical approaches. Nowadays plant-mediated green synthesis and eutectic-based ionic liquids of NPs are obtaining more consideration among investigators worldwide. Wastewater typically contains a mixture of organic and inorganic substances, including azo dyes that can affect water quality and clarity, harmful microorganisms such as bacteria, viruses, and parasites and heavy metals like lead, mercury, cadmium, and chromium. Thus, Green synthesized NPs can be utilized in wastewater treatment owing to their high efficacy and biocompatible property. In this keynote speech numerous NPs were biologically synthesized using both plant extract and eutectic-based ionic liquid medium. Then the mechanism of the NPs formation will be introduced and systematically explained. After that numerous characterization techniques for characterizing the synthesized NPs by both plant extract and eutectic-based ionic liquids mediums will be introduced. These techniques include UV-Vis and FTIR spectroscopy analysis, XRD and EDX analysis, SEM and TEM images, DLS and zeta potential analysis, BET surface area analysis and vibrating-sample magnetometer (VSM) dynamic technique for measuring the magnetic moment for magnetite NPs. After synthesizing the NPs, they have been used for wastewater treatment application. The antibacterial activity of the biosynthesized NPs, azo dyes degradation and heavy metal ions removing have been studied intensively. The comparison between both mediums also presented and the differences have been entirely highlighted. This study showed that the green synthesized NPs, from both medium, are highly proficient for recycling and removal of heavy metal from wastewaters without loss of their stability and degradation of a variety of organic pollutants from wastewaters and, thus, purify the wastewaters for reuse and recycling and could solve various water quality issues worldwide.
