Abstract null null The development of composite films with enhanced antibacterial and dye decolorization properties for water treatment has attracted a great attention. In this study, nickel oxide/chitosan/polyvinyl alcohol nanocomposite films containing different weight percentage of NiO nanoparticles with a dual functionality, removal of toxic dye and antibacterial properties, were prepared. Methyl orange (MO) was selected as a target pollutant. Additionally, the antimicrobial activity of the films against two Gram positive bacteria (Staphylococcus aureus and Bacillus cereus) and two Gram negative bacteria (Escherichia coli and Salmonella Typhimurium) was studied. The prepared samples were characterized by XRD, HRTEM, FESEM, ATR-FTIR, UV–Vis spectroscopy, and dielectric measurements. The morphological examination proved that the nanocomposite film has more porous structure compared to the unmodified chitosan/PVA. The antimicrobial tests indicated that the modified chitosan/PVA films have higher activity than pure chitosan/PVA toward all the tested pathogenic bacteria. The impact of the NiO amount (0.5, 1.5, 3, and 5 wt%), contact time (0–150 min), and adsorbent dose (40, 80, and 100 mg) on the removal of MO was studied. Dye adsorption results proved that the incorporation of 5 wt% NiO led to more than 2 fold increase in the dye removal percentage in comparison with the unmodified PVA/chitosan film.

Abstract Herein, we present the effect of ethylene glycol (EG) concentration on the size of CdO–NiO–Fe2O3 nanocomposites with the intention to enhance their structural and optical properties for antibacterial activity. The self-combustion method was used to prepare trimetal oxide (TMO) nanocomposites. Structural and morphological properties of the prepared samples were studied using X-ray diffraction (XRD) and transmission electron microscopy (TEM), respectively. Absorbance and photoluminescence...

Abstract In this study, the toxic cationic dye of methylene blue (MB) was encapsulated by the polymeric natural carbohydrate of turmeric powder (TP) adsorbent. The natural TP adsorbent was characterized to define the functional groups existing for complexation ability to the MB dye molecules. The MB dye adsorption system was optimized by varying the parameters of contact time, pH, initial concentration, competing ions and elution operations. The contributions of adsorption and complexation on MB...

Abstract Herein, MnFe2O4/reduced graphene oxide nanoparticles (MrGO) were synthesized for the effective removal of various cationic dyes. The synthesized nanocomposites exhibited high adsorption capacity for removing cationic dyes as malachite green dye MG and methylene blue dye MB reaching 156, and 105 mg/g at 30 °C, respectively. The high surface area of the prepared adsorbent, 95 m2/g, electrostatic interaction, and π-π interaction facilitated dyes removal on MnFe2O4/rGO. The physicochemical ...

Abstract Removal of dyes from treated wastewater is intricate problem and to solve that many techniques such as adsorption, advanced oxidation, ion exchange, catalytic degradation and biodegradation etc. are under investigation. Among these, adsorption is considered as most appropriate method. Graphene Oxide (GO) is having wide range of oxygen functional groups, unique electronic, thermal, and mechanical properties which makes it suitable for adsorptive removal of dyes. The present study deals w...

Polyblend samples of chitosan/poly(vinyl alcohol) (PVA) have been prepared using a casting technique. Scanning electron microscopy, Fourier transform infrared spectroscopy and thermogravimetric analysis measurements revealed that chitosan and PVA are compatible with each other. Alternate current (AC) conductivity and dielectric relaxation features of pure and polyblend samples are analysed in the frequency range of 0.1 Hz to 100 kHz covering a broad temperature range from room temperature to 423...

Abstract In this article the NiO nanoparticles were synthesized by onion extract (green synthesis) as well as by quercetin (chemical method) which were synthesized successfully. Quercetin is one of the major phytochemical of red onion which was studied separately (as chemical) and in onion extract for the synthesis of NiO NPs. The comparative study shows that quercetin solution works as reducing and capping agent for the synthesis of NiO NPs meanwhile extraction of onion works in the same way. T...
Abstract The endless introduction of toxic dyes through industrialization has worsened the dyes pollution in the environment. As a consequence, the need for the effective removal of such dyes has become more crucial than before. Recently, polymeric membranes for dye adsorption are gaining tremendous attention. In this context, we synthesized the polyethylene oxide/polyaniline (PEO/PANI) composite membrane by a very simple and cost effective approach for the first time. The removal of methyl oran...

Abstract In this research, an attempt to develop zwitterion composite adsorbent is conducted by modifying chitosan (CHS) with a covalent cross-linker (epichlorohydrin, ECH) and an aluminosilicate mineral (zeolite, ZL). The zwitterion composite adsorbent of chitosan-epichlorohydrin/zeolite (CHS-ECH/ZL) is performed multifunctional tasks by removing two structurally different cationic (methylene blue dye, MB), and anionic (reactive red 120 dye, RR120) dyes from aqueous solutions. The surface prope...

Abstract null null Increasing antimicrobial resistance has led to use of novel technologies such as nanomaterials and nanocomposites that have shown effective antimicrobial and/or antifungal activities against several gram-positive and gram-negative bacteria. There have been limited studies on antimicrobial properties of the combined polymer nanocomposites with transitional bimetallic nanoparticles such as nickel (Ni) and copper (Cu). Thus, the main objective of this study was to synthesis, char...
