Spectroscopic and chromatographic studies of chemical constituents of wild A.pindrow royle: facile foliar fuel for the synthesis of nanomaterials.

The current work is the first ever report on the functionalization of CoO nanoparticles (NPs) using the bio active constituents of Abies pindrow Royle (A.pindrow) leaves. An efficient phytochemical extraction method was determined by comparing different extraction strategies for extracting the biologically active compounds of A.pindrow leaves. The phytocompounds were noticed via chromatographic techniques; High-performance liquid chromatography (HPLC) as well as the Gas chromatography-mass spectroscopy (GC-MS) followed by spectroscopic analysis that is the Fourier transform infrared spectroscopy (FTIR) along with Ultraviolet-visible spectroscopy (UV-Vis). The reducing properties of the phytochemicals were investigated by efficiently synthesizing metal oxides nanoparticles (CoO NPs) by treating aqueous plant extract with Co(NO3). 6H2O aqueous complex. The newly synthesized NPs were characterized via X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDX) and field emission-scanning electron microscopy (FE-SEM). Finally, the GCMS, FTIR and UV-Vis identified the A.pindrow leaves biocomponents as capping and reducing mediator of the synthesized CoO nanoparticles. FTIR confirmed the prepartion of CoO NPs as well as the capping and stabilizing agents of A.Pindrow at 2378.31 cm-1, 1370.11 cm-1, 1260.57 cm-1, 937.4 cm-1 and 607.24 cm-1 having carboxylic acid, alcohols, aromatics, alkenes, aromatic amines, esters as well as ethers functional groups, flavonols and flavonoids phytochemicals. Moreover GCMS analysis revealed the dominating constituents of A.pindrow leaf extracts are carbohydrates, terpenoids, alkanoids, flavonoids as well as phenols. Furthermore, the antibacterial and bioactive agent, tannis was also observed in aqueous extract. These phytochemicals noticed in this current work, has antioxidant potential, that is why they have shown biomedical applications. The present manipulation, further articulated that, maximum phytochemicals extraction of A. pindrow leaves was illustrated in the aqueous extract as compared to ethyl acetate and ethanol.

Synthesis and Analysis of Euphorbia cognata Boiss-Assisted Organic-Inorganic Complex: Photosynthesis and Stabilization of CoO Nanoparticles.

Synthesis of metal oxide nanomaterials using phytochemicals has now been regarded as mutually exclusive to chemical synthesis techniques. Here, we have extracted, isolated, and characterized the phytochemicals of Euphorbia cognata Boiss leaf hydro-organic extract and utilized them as biofuel in the preparation of metal oxide nanoparticles (CoO NPs). To evaluate the chemical composition of bio templates, chromatographic techniques like high-performance liquid chromatography (HPLC) and gas chromatography-mass spectroscopy (GC-MS) were being utilized. The reducing properties of the organic fuel were investigated by efficiently synthesizing CoO NPs by treating aqueous plant extract with an aqueous complex of Co(NO3)·6H2O. X-ray diffraction (XRD) was utilized for identification of newly prepared NPs, and composition of elements was inveterate via energy dispersive X-ray spectroscopy (EDX). The spherical-shaped morphology was noticed via field emission-scanning electron microscopy (FE-SEM), and the biocomponents of synthesized metal oxide were identified by GC-MS which has confirmed the active presence of monopolized octodrine, decanoic acid, cathinone, and acetic acid in the synthesized metal oxides NPs. Overall, the present study has demonstrated well the significant potential of E. cognata phytocompounds as fuel in the synthesis of nanomaterial.

Amine-Decorated Methacrylic Acid-based Inverse Vulcanized Polysulfide for Effective Mercury Removal from Wastewater.

Mercury [Hg(II)] contamination is an indefatigable global hazard that causes severe permanent damage to human health. Extensive research has been carried out to produce mercury adsorbents; however, they still face certain challenges, limiting their upscaling. Herein, we report the synthesis of a novel amine-impregnated inverse vulcanized copolymer for effective mercury removal. Poly(S-MA) was prepared using sulfur and methacrylic acid employing the inverse vulcanization method, followed by functionalization. The polyethylenimine (PEI) was impregnated on poly(S-MA) to increase the adsorption active sites. The adsorbent was then characterized byusing Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM). FTIR spectroscopy confirmed the formation of the copolymer, and successful impregnation of PEI and SEM revealed the composite porous morphology of the copolymer. Amine-impregnated copolymer [amine@poly(S-MA)] outperformed poly(S-MA) in mercury as it showed 20% superior performance with 44.7 mg/g of mercury adsorption capacity. The adsorption data best fit the pseudo-second-order, indicating that chemisorption is the most effective mechanism, in this case, indicating the involvement of NH2 in mercury removal. The adsorption is mainly a monolayer on a homogeneous surface as indicated by the 0.76 value of Redlich-Peterson exponent (g), which describes the adsorption nature advent from the R2 value of 0.99.
