Remediation of industrial discharged dyes to the water bodies is much needed in the current scenario. Here in this, we prepared silver nanoparticles using Anisomeles malabarica. The synthesized nanoparticles were characterized by Fourier transform infrared study, scanning electron microscopy, dynamic scanning calorimetry, and thermogravimetric analysis. All the characterization studies suggested that the formation of silver nanoparticles was successful. The synthesized silver nanoparticles were used as an adsorbent to adsorb the methylene blue. To achieve this, optimum pH of the adsorbent to adsorb the dye was studied, and it was found to be pH 7. The adsorbent dose to adsorb the dye was found to be 0.1 g/L. From the isotherm theoretical studies, it was found that the adsorption isotherm follows Langmuir adsorption, and the q max was found to be 97.08. From the kinetic study, the rate of the reaction follows the pseudosecond-order kinetics with regression > 0.9 . From the study, it was inferred the nanoparticles synthesized can act as a good adsorbent and can be used to purify the wastewater contaminated with methylene blue.

Zinc oxide nanoparticles (ZnO NPs) were prepared by co‐precipitation of zinc acetate with Ampelocissus martini rhizome extract (AM). Four conformations of ZnO NPs were obtained by conjoined precipitation of sodium hydroxide, zinc acetate dihydrate, and AM: ZnO NPs‐01, ZnO NPs‐02, ZnO NPs‐03, and ZnO NPs‐04. The structure of ZnO NPs was confirmed by X‐Ray diffraction (XRD). Fourier transform infrared (FTIR) analysis was conducted to identify functional groups. The formation and morphology of the synthesized ZnO NPs were confirmed by field emission scanning electron microscopy (FE‐SEM) with Energy dispersive X‐ray spectroscopy (EDS) mapping, and transmission electron microscopy (TEM). Free radical scavenging activity was determined by 2,2‐diphenyl‐1‐picryl‐hydazyl‐hydrate (DPPH) and 2,2/‐azino‐bis‐(3‐ethylbenzothi‐azoline‐6‐sulfonic acid (ABTS) assays. Antibacterial activity was examined by disc diffusion analysis together with minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC). ZnO NPs‐04 showed the highest inhibition in DPPH and ABTS assays and was active against E. coli and S. aureus with MICs=10 mg/mL and 5 mg/mL, respectively. These findings indicated that synthesized NPs could be utilized for several medicinal applications.
