The effective removal of nitrophenols from wastewater is crucial due to their high carcinogenic risk. This research presents the development a copper-based metal-organic framework (HKUST-1) integrated into chitosan-graft-poly(acrylic acid) hydrogel. hydrogel composite was evaluated as catalyst for reducing and dyes using sodium borohydride (NaBH4) agent. Various conditions were investigated reduction 4-nitrophenol (4-NP) less harmful 4-aminophenol (4-AP), including dosage, NaBH4...
This study describes the fabrication of composite beads comprising chitosan and zeolitic imidazolate framework-8 (ZIF-8) as a natural biodegradable dye adsorbent support for ZnO photocatalyst.
The study involved the synthesis of magnetite (Fe3O4) and zeolite-supported Fe3O4 (Fe/Z) using co-precipitation (COP) hydrothermal (HYD) methods which proved effective for removing Cr(vi) from contaminated water. X-ray diffraction (XRD) analysis showed that phase had a cubic crystal structure. COP method resulted in lower crystallinity compared to HYD method. different preparation also led variations morphologies sizes particles. HYD-prepared sample exhibited uniform spherical shape with...
As a result of the growth industrialization and urbanization, water ecosystem is contaminated by various pollutants, including heavy metal ions dyes. The use low-cost environmentally friendly dye adsorbents has been investigated. A hydrogel was fabricated via graft polymerization acrylic acid (AA) 2-acrylamido-2-methyl-1-propanesulfonic (AMPS) onto chitosan. used as adsorbent support for zinc oxide (ZnO) powder photocatalyst. adsorption capacity bare greater towards cationic dyes than...
Zeolitic imidazolate framework-67 (ZIF-67) was synthesized
Abstract Proton conducting membranes based on crosslinked poly(vinyl alcohol) and chitosan were fabricated using sulfosuccinic acid (SSA) glutaraldehyde (GA) as crosslinking agents. A systematic study the effects of SSA, chitosan, GA membrane properties was conducted. The most promising then chosen to form composites with silica particles containing poly(2‐acrylamido‐2‐methyl‐1‐propanesulfonic acid) (PAMPS‐Si). Two different sizes PAMPS‐Si similar PAMPS contents synthesized from...
Simple approaches for developing sensitive fluorescence sensors 2,4-dinitrotoluene (DNT) detection were reported.Pyrene-doped poly(methyl methacrylate) (PMMA) and poly(vinyl chloride-co-vinyl acetate-co-vinyl alcohol) (PVC terpolymer) fibres, polystyrene (PS) poly(styrene-co-methyl (PS-co-PMMA) fibres prepared via electrospinning technique.Fibre morphology was studied using scanning electron microscopy.Sensing performance towards DNT monitored through emission of pyrene.The time dependence...
