Polyacrylonitrile modified partially reduced graphene oxide composites for the extraction of Hg(II) ions from polluted water

Polyacrylonitrile nanoparticles grafted on ethylene diamine functionalized partially reduced graphene oxide (PAN-PRGO) was prepared via in situ emulsion polymerization and was further modified to contain amidoxime, amdinoethylene diamine, and carboxylic groups on the surface of the graphene nanosheets via partial hydrolysis of the nitrile groups on the polymer chains of the composite using (4% NaOH, 20 min) (HPAN-PRGO). The properties and morphologies of the prepared composites were compared through FTIR, UV-Vis, Raman spectra, XRD, SEM, TEM, and XPS analysis. The results revealed that polyacrylonitrile nanoparticles were grafted on the surface of the aminated graphene oxide nanosheets via the reaction between the free amino groups of the ethylene diamine modified graphene oxide nanosheets and nitrile groups of acylonitrile (AN). The obtained HPAN-PRGO composite was evaluated for its chelating property with Hg(II) ions. The effect of initial pH, initial concentration of the Hg(II), adsorbent dose, and contact time on the extraction of Hg(II) ions using HPAN-PRGO were investigated. The adsorption experiments indicated that HPAN-PRGO exhibits higher affinity toward Hg(II). The maximum uptake capacity for the extraction of Hg(II) ions on HPAN-PRGO was 324.0 mg/g at pH 5. The HPAN-PRGO shows a 100% removal of Hg(II) at concentrations up to 50 ppm, and the adsorption is exceptionally rapid showing more than 80.0% removal within 15 min and 100.0% of q(e) within 1.5 h at 800 ppm concentration. The Langmuir isotherm model and pseudo-second-order kinetic model have showed good fitness with the practical data. The XPS analysis of HPAN-PRGO before and after adsorption revealed the chelation adsorption mechanism between mercury and amine, amide, amidoxime, and carboxylic groups. After six adsorption-desorption cycles, the HPAN-PRGO could retain more than 90.0% of its original adsorption capacity. These results confirmed that HPAN-PRGO has exceptional performance for the removal of Hg(II) from wastewater. [GRAPHICS] .

2-(3-pyrrolin-1-yl)-1,4-naphthoquinones: Photoactivated alkylating agents

The preparation of 2-(3-pyrrolin-1-yl)-1,4-naphthoquinones and a study of their use as photoactivated alkylating agents is reported. The title compounds were easily synthesized by conjugate addition of the corresponding 3-pyrrolines to various naphthoquinones. Upon exposure to ambient room light, the compounds undergo an internal redox reaction to form 2-(pyrrol-1-yl)-1,4-hydroquinones, which are activated for nucleophilic addition by an S(N)1 azafulvene mechanism. Control experiments demonstrated that the redox reaction is triggered by light and that the nucleophilic addition does not proceed before this activation occurs. ((C) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008).

N-benzyl-5-hydroxy-3-pyrrolidin-2-one by hydrogen peroxide oxidation of n-benzyl-3-phenylseleno-2-pyrrolidinone

Using the known peroxide oxidation of N-benzyl-3-phenylseleno-2-pyrrolidinone with 30% hydrogen peroxide at – 5 degrees C after 3.5 h, we prepared the expected N-benzyl-3-pyrrolin-2-one. However, reaction with 30% hydrogen peroxide for 12 h (-5 degrees C -> ambient) gave the unexpected product N-benzyl-5-hydroxy-3-pyrrolidin2-one in 84% isolated yield. This procedure is a new synthetic route to N-benzyl-5hydroxy-3-pyrrolidin-2-one.

Photooxygenation of 5-dialkylamino-4-pyrrolin-3-ones. synthesis of highly functionalized ureas, 2-oxazolidinones, and 2-oxazolinones

5-Dialkylamino-4-pyrrolin-3-ones, available from cyclocondensation of amidines with dimethyl acetylenedicarboxylate (DMAD), undergo rapid singlet oxygenation to give highly functionalized ureas by way of a 1,2-dioxetane cleavage of the initially formed [2 + 2] cycloadducts. These latter compounds undergo cyclization to 2-oxazolidinones in MeOH. Catalytic hydrogenation of the ureas in EtOAc gives 2-oxazolinones. The DBU-DMAD adduct undergoes photooxygenation by an entirely different pathway to give a large ring heterocycle.

Disinfection technology and strategies for COVID-19 hospital and bio-medical waste management

The isolation wards, institutional quarantine centers, and home quarantine are generating a huge amount of biomedical waste (BMW) worldwide since the outbreak of novel coronavirus disease-2019 (COVID-19). The personal protective equipment, testing kits, surgical facemasks, and nitrile gloves are the major contributors to waste volume. Discharge of a new category of BMW (COVID-waste) is of great global concern to public health and environmental sustainability if handled inappropriately. It may cause exponential spreading of this fatal disease as waste acts as a vector for SARS-CoV-2, which survives up to 7 days on COVID-waste (like facemasks). Proper disposal of COV1D-waste is therefore immediately requires to lower the threat of pandemic spread and for sustainable management of the environmental hazards. Henceforth, in the present article, disinfection technologies for handling COV1D-waste from its separate collection to various physical and chemical treatment steps have been reviewed. Furthermore, policy briefs on the global initiatives for COVID-waste management including the applications of different disinfection techniques have also been discussed with some potential examples effectively applied to reduce both health and environmental risks. This article can be of great significance to the strategy development for preventing/controlling the pandemic of similar episodes in the future. (C) 2020 Elsevier B.V. All rights reserved.

The corresponding pure pyrrolin-4-ones were obtained in excellent yields (80-98%) directly after a straightforward precipitation-filtration workup, thus avoiding any chromatographic purification. The catalytic system was recycled and the chiral purity of all the products was also investigated.
