Abstract:
The purification of waste cooking oils (WCOs) through clay-based adsorption is an established recycling method, yet the relationship between clay composition and adsorption efficiency remains an area of active research. The aim of the present research work was to assess the performance of Maghnia bentonite in WCO decoloration and to gain information about the specific refining process. Thus, natural bentonite from the Maghnia region (Algeria) was investigated as an adsorbent for WCO refining for biolubricant production. The adsorption efficiency was evaluated under different conditions, achiev

Abstract:
Isotactic polypropylene (iPP)/bentonite nanocomposites were prepared via melt blending using bentonite clay originated from Maghnia (Algeria). This clay was, at a first stage, used in its pure form (PBT) and then organically modified by Hexadecyl ammonium chloride (OBT). The effect of Maghnia bentonite dispersion on the iPP matrix was investigated by X-ray diffraction (XRD) and transmission electronic microscopy (TEM). DSC results evidenced that unmodified or organomodified bentonite can act as a nucleating agent increasing the rate of crystallites formation. Moreover, a thermogravimetry analy

Résumé Une argile naturelle, la bentonite de Maghnia (ouest d’Algérie), a été purifiée et caractérisée par calcination, pH‑métrie, IR, XRD et SEM. Les résultats obtenus ont montré que l’argile a une conductance de 66,4 µS, une capacité d’échange cationique (CEC) de 0,91 méq/g et contient 12 % de matières organiques. Les caractérisations par IR, XRD et SEM ont montré que la bentonite de Maghnia (B) est composée de quartz comme impureté majeure, d’illite (7 %) et principalement de montmorillonite. Cette argile a été saturée au sodium (Na+) et associée au fer (III), à l’aluminium (III) et au cuiv

Abstract:
The compatibilization of raw bentonite (bent) with a polymer matrix of polypropylene (PP) can improve the performance of the material in terms of thermal and mechanical properties. In this study, two kinds of untreated bentonite, bentonite-Maghnia (bent-m) and bentonite-Mostaganem (bent-M), that differ in the proportion of Al2O3 and in the particle size distribution were coupled to typical maleic anhydride grafted polypropylene PP-MA. Stearic Acid (SA) and L-leucine Amino Acid (AA) were selected as new coupling modifiers at a 5/5 ratio of bentonite/coupling agent. All PP/bent composites were p

Abstract:
The objective of this study is to evaluate the performance and capacities of the bentonite of Maghnia, modified with benzyldimethyltetradecylammonium chloride, to remove the organic pollutant 2,4,6-Trichlorophenol (TCP). The modified sample was studied by X-ray diffraction (XRD) technique, infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA) methods. The best removal rate (99.52%) was obtained at 19°C, pH 4, solution concentration of 50 mg/L, stirring speed of 180 rpm and contact time of 60 min. The results were well fitted by both Langmuir and Freundlich isotherm models and

Abstract:
In this work, a bentonite from Maghnia (northwestern Algeria) was used as a gelling agent in gel and emulgel formulations. The percentage of Na-bentonite in the formulations was fixed at 5%. The physical appearance of the formulated gel and emulgel was characterized before determining their pH, viscosity and swelling index. A rheological analysis demonstrated the characteristic shear thinning and viscoelastic behavior of the formulations using thixotropy. Stability studies showed that the physical appearance and rheological properties of the prepared gel and emulgel remained unchanged having b

Abstract:
The objective of this study is the variation of natural and modified clays and their use in industrial waste treatment. For this purpose, we carried out several elimination tests of the effluents by adsorption by using two natural clays from different deposits, namely bentonite located in Maghnia and Djabel Debbagh of Ain Berbar and bentonite coupled with cellulose. The adsorption test was performed on a Decis pesticide. The clays that we tested, in the natural state and in the modified state, are the object of a mineralogical and physicochemical characterization by various techniques of analy

This contribution focuses on the synthesis and characterization of nanocomposites based on poly (ethyl methacrylate-co-acrylonitrile) (PEMAN) and different loadings of an organically modified bentonite from Algeria prepared via in situ polymerization. TEM images and X-ray patterns revealed that depending on the loading of this clay, intercalated or partially exfoliated nanocomposites were obtained. These nanocomposites showed an increase in their glass transition temperature compared to the pure copolymer as investigated by Differential Scanning Calorimetry and improved thermal stability
