Co-catalytic effect of WS2 on the copper slag mediated peroxodisulfate activation for the simultaneous elimination of typical flotation reagent benzotriazole and Cr(VI)
(Elsevier, 2023)
In this study, efficient simultaneous elimination of typical mine pollutants benzotriazole (BTA) and Cr(VI) was achieved by using a copper slag (CS) activated peroxodisulfate (PDS) Fenton system, with WS2 as a co-catalyst. ...
Simultaneous removal of typical flotation reagent 8-hydroxyquinoline and Cr(VI) through heterogeneous Fenton-like processes mediated by polydopamine functionalized ATP supported nZVI
(Elsevier, 2022)
The heavy metal and organic pollution caused by mining activities keep attracting attention, thus an economic and efficient treatment for combined pollution is pressing. In this study, the simultaneous removal performance ...
Resource utilization of steel converter slag: Efficient degradation of typical organic flotation reagent α-nitroso-β-naphthol via the synergy of radical and non-radical pathways
(Elsevier, 2023)
The organic pollution generated during production and processing in the mining area seriously endangers the ecological security of the surrounding environment. In this study, degradation of α-nitroso-β-naphthol (αNβN), a ...
Stereoselective Construction of Fluorinated Quaternary Stereogenic Centers via an Organocatalytic Asymmetric exo-Selective Diels-Alder Reaction in the Presence of Water
(USA : American Chemical Society, 2022)
A catalytic, asymmetric Diels-Alder reaction of α-fluoro α,β-unsaturated aldehydes and cyclopentadiene was developed using diarylprolinol silyl ether as an organocatalyst. The reaction proceeds in toluene with trifluoroacetic ...
Nanocomposite co-catalysts, based on smectite and biowaste-derived carbon, as peroxymonosulfate activators in degradation of tartrazine
(Elsevier, 2022)
Chitosan (Ch)-derived from biowaste along with smectite, an abundant clay mineral, were used in a low-cost and eco-friendly synthesis of a new type of catalyst. Nanocomposite catalysts constituted of Co supported on smectite ...
Degradation of three typical hydroxamic acids collectors via UVA-B activated H2O2 and persulfate: Kinetics, transformation pathway, DFT calculation and toxicity evaluation
(Elsevier, 2023)
This work systematically studied the kinetics and mechanism of degradation of salicylhydroxamic acid (SHA), benzhydroxamic acid (BHA) and N-hydroxyphthalimide (NOP) by UVA-B/H2O2 and UVA-B/peroxodisulfate (PDS). UVA-B ...
Batch and column adsorption of cations, oxyanions and dyes on a magnetite modified cellulose-based membrane
(Springer, 2020)
Abstract: An optimized method is presented to make magnetite (MG) modified cellulose membrane (Cell-MG) from 3-aminopropyltriethoxysilane and diethylenetriaminepentaacetic acid dianhydride functionalized waste cell fibers; ...
Design of an ethidium bromide control circuit supported by deep theoretical insight
(Elsevier, 2023)
We have set-up an electrochemical advanced oxidation process for ethidium bromide (1), based on the Eu-doped MnWO4 (Eu:MnWO4), obtained through a template-driven synthesis, along with developing a suitable monitoring method. ...
Degradation of novel mineral flotation reagent 8-hydroxyquinoline by superparamagnetic immobilized laccase: Effect, mechanism and toxicity evaluation
(Elsevier, 2022)
The environmental impact of the mining industry requires efficient and eco-friendly technologies to mitigate the presence of mineral flotation reagents (MFRs) in mineral processing wastewater (MPW) prior to their discharge ...
Bacterial nanocellulose as green support of platinum nanoparticles for effective methanol oxidation
(Elsevier BV, 2022)
Bacterial nanocellulose, BNC, has emerged as a new class of nanomaterials recognized as renewable, biodegradable, biocompatible and material for versatile applications. BNC also proved as a perfect support matrix for ...
