Abstract
The release of textile dyes from the industries to the environment has become a significant health issue to humans and their surroundings, where a large number of dyes are wasted to the nearby water during the dyeing process. Therefore, the practice of the utilization of biosynthesized nanoparticles from numerous biological systems has been described, out of which plant material is considered the most appropriate method. The usage of plant material not only makes the procedure ecological but also their abundance makes it more cost-effective. The present study aims to biologically produce selenium nanoparticle using Mucuna pruriens seed powder and apply it in the degradation of dyes and removal of pathogenic bacterial cultures from pathogen-containing lake water using an optimum concentration of selenium nanoparticles. The production of selenium nanoparticles was characterized via visual coloration from colorless to brown solution which was checked using UV–Visible spectrophotometer, the crystalline structure was analyzed using X-ray diffraction, the morphology was analyzed with transmission electron microscopy, scanning electron microscopy, dynamic light scattering, which was in the range of 90–120 nm, with stable spherical monodisperse characteristics. The surface potential was checked using zeta potential, while the Atomic Force Microscopy gave information on the roughness of the nanoparticles, and the presence of –OH, −COO, aromatic groups were confirmed with Fourier Transform Infrared spectroscopy. The biosynthesized nanoparticles were then analyzed for its environmental applications, like degradation of dyes from industrial wastes and checking its antimicrobial activities.
Highlights
The recent developments in the field of nanoscience have garnered significant attention from various sectors since they can be utilized for detection, diagnostics, purifying industrial waste [1], role in energy production or utilization, catalysis [2], food technology [3] and therapeutics [4]
The differences in the arising of color over the various pH could be due to the presence of different dissociated functional groups of M. pruriens that are involved in the biosynthesis procedure [27, 28]
The biosynthesis of selenium nanoparticles (SeNPs) mediated through a green route using seed extract of M. pruriens at physiological conditions like room temperature, is a procedure which is simple, eco- friendly and highly efficient
Summary
The recent developments in the field of nanoscience have garnered significant attention from various sectors since they can be utilized for detection, diagnostics, purifying industrial waste [1], role in energy production or utilization, catalysis [2], food technology [3] and therapeutics [4]. Menon et al Sustainable Environment Research (2021) 31:2 as transporters of selenium compounds, which would raise the bioavailability of this component and permit its controlled release in the organism, has become a target to many researchers. It is a critical micronutrient and a metalloid (either metal or non-metal), and its supplementation gives various medical advantages. Selenium supplementation during fermentation with sugar beet molasses is found to be helpful in the production of fuels like bioethanol, which are clean and cost-effective in comparison to the alternate options [6,7,8,9,10,11]
