Development of nanofiber membranes with the ability to remove organic dye such as Indigo Carmine (IC) from effluent wastewater is of immense help to the textile industry. In the present study, we investigate the preparation of cellulose acetate (CA) nanofiber membranes with optimized performances using electrospinning technique for effective removal of Indigo Carmine (IC) dye. Electrospinning parameters and solvent system containing acetic acid were adjusted to obtain CA nanofibers membranes which better suits dye removal application.

Our present study focuses on examining the thermal, structural and luminescent characteristics of sodium barium metaphosphate glasses doped with Sm. Glass samples with molar compositions (100 - )[(50PO)-(50-NaO)-(BaO)]-SmO, where = 20, 25, 30, 35, 40 and = 0.3 and 1% were first synthesized by conventional melt quenching and later dehydroxylated under a constant N flow to ensure final glasses with a very high degree of chemical and optical homogeneity and free of water.

Easy separable, floatable, and recyclable magnetic-biochar/alginate bead as super-adsorbent for adsorbing copper ions in water media.

Bioresour Technol

September 2023

Center for Energy and Environmental Materials, Institute of Fundamental and Applied Sciences, Duy Tan University, Ho Chi Minh City 700000, Viet Nam; Faculty of Environmental and Chemical Engineering, Duy Tan University, Da Nang City 550000, Viet Nam.

This work aimed to develop innovative material by combining properties of magnetic-biochar (derived from peanut shells) and hydrogel bead (MBA-bead) and apply it for adsorbing Cu in water. MBA-bead was synthesized by physical cross-linking methods. Results indicated that MBA-bead contained ∼90% water.

Porous Gelatin Membranes Obtained from Pickering Emulsions Stabilized with h-BNNS: Application for Polyelectrolyte-Enhanced Ultrafiltration.

Membranes (Basel)

July 2020

Institut Européen des Mem branes, IEM UMR 5635, Univ Montpellier, CNRS, ENSCM, Place Eugene Bataillon, 34095 Montpellier, France.

In recent years, numerous studies have been conducted to develop biopolymer-based membranes, highlighting the challenges to prepare porous structures with control porosity. In this paper an innovative method that relies on the generation of Pickering emulsions was developed to prepare porous membranes from gelatin for filtration purpose. Hexagonal boron nitride nanosheets (h-BNNS) were used to stabilize micro-droplets of castor oil in a continuous homogeneous gelatin solution.

Polyphenolic extracts from the xerophyte Rhamnus lycioides as a radiation biodosimeter.

Environ Sci Pollut Res Int

February 2020

Laboratory "Energy and Matter for Development of Nuclear Sciences" (LR16CNSTN02), National Center for Nuclear Sciences and Technology, Sidi Thabet Technopark, 2020, Sidi Thabet, Tunisia.

The majority of dosimeters currently in use are synthetic and very expensive. Therefore, the study of the dosimetric characteristics of polyphenolic extracts of xerophytes is useful because drought stress causes an increase in the production of these cheap and natural compounds containing benzene rings. Here, the polyphenolic compounds were extracted from Rhamnus lycioides which was collected from Bou-Hedma National Park in Tunisia and identified using liquid chromatography-mass spectrometry (LC-MS).

Iron removal from brackish water by electrodialysis.

Environ Technol

March 2014

Desalination and Water Treatment Research Unit, Faculty of Sciences of Tunis, El Manar 11H 2092, Tunis, Tunisia.

The aim of this work is to study the removal of iron from brackish water using electrodialysis (ED). Experiments were carried out on synthetic brackish water solutions using a laboratory-scale ED cell. The influence of several parameters on process efficiency was studied.
