In this report, a composite adsorbent in form of spherical beads generated from graphene oxide, chitosan, and magnetite (MGOCS) was developed characterized by X-ray powder diffraction, Fourier transform infrared spectroscopy, field emission scanning electron microscope, vibrating sample magnetometer. The adsorption ability MGOCS towards reactive blue 19 (RB19) Ni(II) ions, the effect various experimental factors including pH, dosage, contact time, adsorbate concentration, temperature, ionic...
Magnetic activated carbon/chitosan composite (MACCS) beads from spent coffee grounds and shrimp shells were synthesized using green tea extract as a crosslinker. The adsorbent was then applied for removal of Ni(II) ions aqueous solution after carefully characterizing it by various techniques (XRD, FTIR, FE-SEM, EDX, VSM BET). adsorption kinetics, isotherms, thermodynamics, the effects key factors such pH value, initial concentration, contact time, dose temperature investigated in detail. A...
In this work, we successfully demonstrated the facile fabrication of highly flexible and floatable Cu2O/rGO on Vietnamese traditional paper (VTP) for solar-light-driven photocatalytic degradation antibiotic ciprofloxacin. The catalyst membrane was prepared by green reduction both Cu(OH)2 to Cu2O nanoparticles graphene oxide reduced oxide. VTP has a fibrous structure with tiny fibers connected like spider web multiple layers in form multidimensional array, which functions as porous supporter...
The presented investigation attempts to offer a robust, simple, cost-effective AgNPs/MnO2/ErGO composite simultaneously determine piroxicam (PRX) and ofloxacin (OFX). material is prepared via facile depositions of MnO2 Ag species on graphene oxide followed by an electroreduction. achieved (i.e., AgNPs/MnO2/ErGO) exhibits intimate interfacial contacts, promoting charge transfer mass transport. Consequently, the sample AgNPs/MnO2/ErGO-decorated glassy carbon (GC) electrode (denoted...
CeO x -anchored β-Ni(OH) 2 nanosheets onto nickel foam electrodes have been developed for the efficient energy-saving hydrogen production via electrocatalytic glucose oxidation reaction.
Abstract The treatment of dyes and heavy metals in aqueous solutions is a major environmental concern, many methods have been developed to address this problem. However, most these focus on treating either or their own limitations. Therefore, process that can simultaneously remove both large scale essentially required. In study, we synthesized magnetic activated carbon (MAC) derived from Litsea glutinosa seeds, which was applied eliminate methylene blue nickel ions the aeration tank...
In this work, the quinone based 3,3′,5,5′-tetra-tert-butyl-4,4′-stilbenequinone was tested as a catalyst in sulfide oxidation aqueous medium. On basis of obtained experimental results, catalytic cycle presence stilbenequinone has been established.

The aim of this study is to monitor the kinetics and mechanism liquid-phase oxidation inorganic sulphide by oxygen in presence a catalyst based on 3,3′,5,5′-tetra-tert-butyl-4,4′-stilbenequinone. research results point out that reaction has first order with respect each reactant. effects temperature, initial concentration, intermediate final products, nature sulphides as well concentration aqueous efficiency were investigated. catalytic cycle sodium...
In this study, the kinetics and mechanism of reaction sulfide oxidation catalyzed by hydrocarbon solution 3,3′, 5,5′-tetra-tert-butyl-stilbenequinone have been deeply investigated. The is first order with respect to each reagents. molecular catalysis was discussed, in which elemental sulfur produced at intermediate stages during transformation sulfate. algebraic equations describing transition catalytic from diffusion region kinetic were established. formation strong reactive oxygen species...
The floods in the Vietnamese Mekong Delta have long caused a shortage of clean water supply, which has significant impact on indigenous people region. We conducted preliminary survey quality Hau Giang River (one two main branches River) before, during, and after flood season. obtained results demonstrated that was highly turbid contaminated with large number harmful microorganisms. Thus, this study, simple filter system based silver nanoparticles coated onto activated carbon derived from...
Abstract This study presents a short communication on exploring, for the first time, simple approach selective and highly effective synthesis of tricaproin by synergistically combining silicon tripolyphosphate phosphoric acid in catalytic esterification glycerol with caproic acid.
