The adsorption of two basic dyes, CI Basic Yellow 28 and Green 4, was studied in single binary solute systems using classes inorganic-organic pillared clay granules as sorbents (300-400 microm 700-800 microm). These were prepared by high-shear wet granulation from an Al cetyltrimethylammonium bromide intercalated powder (particle diameter < 50 Adsorption rate data indicate that BY adsorbs more rapidly than BG 4 a pseudo-first-order model found to fit the kinetic curves, with regression...
A modified Sips' energy distribution is proposed to account for Langmuir–Freundlich adsorption isotherms and Mittag–Leffler fractal kinetics.
In this work, the removal of fluoride and Cr(VI) by electrogenerated coagulants is studied in single binary systems.The effects initial pH, current intensity concentration on hexavalent chromium were investigated.The results showed that an optimum was achieved at pH 3.0.Removal efficiencies 96.7% 97.4% for respectively pH.Adsorption kinetics first order rate expression fitted adsorption both Cr(VI).The equilibrium isotherm analyzed Langmuir Freundlich models.The characteristic parameters...
The present study aims to synthesize a hybrid thin film with sol-gel process via dip-coating and spin-coating techniques.Prepared films are used in the elimination several pollutants using photodegradation process.Used prepared by mixing polyvinyl chloride (PVC)/hydrophobic-modified clays (Hc).First, we modified natural bentonite (Bt) sodium montmorillonite (Na-Mt) surfactant cetyltrimethylammonium bromide.incorporation of methylene blue (MB) as photosensitizers into Hc was realised...
The main objective of this study is to develop a new formula for diet mayonnaise-like sauce without cholesterol. Emulsifying power provided by the use soy lecithin and total fat content was limited 16%. Droplet size measurement employed mayonnaise samples at different times show that largest diameter does not exceed 18.5 µm with yield stress 56.1 Pa. Results stability centrifugation reveal absence supernatant oily layer ensures emulsion. Using experimental design method, number trials can be...
The present study aimed to evaluate the potential of mesoporous silica MCM-41 and Al-MCM-41 (molar ratio Si/Al = 20) for removal Rhodamine 6G (Rh6G) from aqueous solution.The adsorbents were characterised by XRD, FTIR, SEM-EDX, BET, UV-Raman.Obtained results related XRD analysis indicated that structure remained intact after incorporation Al species.Kinetic adsorption showed higher (88.75 %, 26.62 mg g -1 ) Rh6G dye was achieved at 60 min.FTIR hydrogen bonding played dominant role in...

This study focus on the optimization of operating conditions for activated carbons preparation starting from synthetic waste (tires) and agricultural (date pits) by chemical activation. The experimental design was used in order to determinate optimal a precursor with high properties. results show that temperature 550°C particle diameter 800 um are interesting. specific surface area reached 770 1030m2/g respectively active obtained tires date pits. In evaluate efficiency these adsorbents, we...
A series of novel resistant granular sorbents based on iron surfactant modified pillared montmorillonite and gluten as binder noted (Fe-GSMPM) are prepared used in adsorption towards hydrosoluble micropollutants.The batch sorption Malachite Green (MG) and/or Rhodamine B (RB) both single binary component systems from aqueous solutions was investigated.In all systems, capacities were depending the pH granule size.In results showed that Fe-GSMPM very effective more quickly with MG than RB...
L’objectif de cette étude est la valorisation énergétique d’un déchet agroalimentaire pour produire du bioéthanol deuxième génération. Il s’agit d’une biomasse lignocellulosique composé pomme terre. La conversion cellulosique en éthanol à usage carburant a été réalisée utilisant un prétraitement acide, suivi par l’étape saccharification présence deux enzymes: cellulase et l’hémicellulase. L’hydrolysat obtenu fin fermenté levure Saccharomyces cerevisiae sous les conditions anaérobiques...
