Polyméthacrylate d'hydroxyéthyle-co-glycidyl méthacrylateIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Hydrogel membranes can swell by a high proportion of their weight and have a large surface area, and are nowadays preferred in adsorption studies. In this work, p(HEMA-GMA) poly(hydroxyethyl methacrylate-co-glycidyl methacrylate) spherical particulated hydrogel membrane (SPM) was produced by UV photopolymerization and the synthesized membrane was coupled with iminodiacetio acid (IDA) in order to bond the Cr(III) ions in the chrome tanning process effluent. Then p(HEMA-GMA)-IDA-Cr(III) SPM was used to remove Acid Black 210 dye from the dyeing process effluent. The membrane's chrome and dye adsorption capacities were determined using a UV/Vis Spectrophotometer at wavelengths of 601nm and 435nm respectively. After the membranes were used, the discharged tanning and dye process wastewaters were examined in order to see the differences in the wastewater in terms of COD, BOD, conductivity, pH, salinity, total dissolved solids, total suspended solids, potassium, total nitrogen and chromium content. The results showed that the metal-chelated p(HEMA-GMA)-IDA SPMs chelated chrome ions between 398.47 and 619.10mg/g, and the adsorbed Acid Black 210 dye molecules were between 0.76 and 1.87mg/g. In conclusion, p(HEMA-GMA)-1DA SPM is an effective sorbent system for removing Cr(III) ions and acid dye molecules from leather discharge waters. Note de contenu : - Characterisation of nano-PHEMA-AB

StatistiqueIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : Contamination of water bodies by organic substances, such as dyes, cause impacts on the environment and human health. Furthermore, the search for environmentally appropriate destinations for solid waste, such as those from agro-industries, has been intensifying, to minimize the impact of the growing generation of waste as a result of population growth. Thus, this work aimed to evaluate the use of raw peanut shells as an alternative adsorbent for the removal of Brown acid dye from synthetic leather dyeing wastewater. The peanut shells were milled and sieved. The material was characterized by Fourier Transform Infrared Spectroscopy. The parameters evaluated in the adsorption tests were pH, contact time, and mass of adsorbent material. The maximum adsorption capacity verified for the peanut shell was 7.753 mg/g and up to 93% of the dye was removed. The best adsorption conditions were at pH 2.5, 10 minutes, and adsorbent mass of 0.3 g in 50 mL of effluent. The results showed relevant removal of the Brown acid dye by the peanut shells’ adsorbent material.

Wet-blue (tannage)Peau tannée au chrome (le chrome donne une couleur bleue)Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The tanning characteristics of starch samples modified by different methods were investigated in our previous studies. In this study, utilization of modified starch in leather making as a retanning agent and its effect on dyeing process have been investigated. For this purpose, the molecular size of native corn starch was reduced by H2O2 oxidation and then carboxymethylated. A series of analyses (water solubility, degree of substitution, Fourier Transform Infrared Spectroscopy, Proton and Carbon Nuclear Magnetic Resonance Spectroscopy) were carried out for characterization. Then, carboxymethyl starches were used in retanning processes to be 3, 5 and 10% based on leather weight and the shrinkage temperatures and filling coefficients of the leathers were determined. Acid and metal complex dyestuffs were used in dyeing processes and the effect of carboxymethyl starch on dyeing was also investigated by examining dye consumption, dry and wet rubbing fastness and color of the leathers. From the results it was concluded that carboxymethyl starch showed a noticeable solo performance in terms of filling property and shrinking temperature without any considerable adverse effect on dyeing.

Membranes échangeuses d'ionsIndex. décimale : 667.3 Teinture et impression des tissus Résumé : The adsorption and desorption performances of CI Acid Red 18 and CI Acid Red 88 on an anion exchange membrane were studied. The effects of temperature, time, pH value and inorganic salt on the adsorption were investigated. The results showed that temperature and pH value had nearly no influence on the dye adsorption. The addition of inorganic salt (sodium sulphate) in the dye solution had a definite influence on the adsorption. The adsorption of the two acid dyes was in accordance with the pseudo-second order dynamics model. The Langmuir adsorption model could describe the adsorption processes well. The membrane was more effective on CI Acid Red 18, which has three sulphonic groups. In the desorption process, different solutions were applied to investigate the desorption performance of the two acid dyes. The desorption percentage could reach ca. 90% using a mixture of ethanol, sodium chloride and water as the desorption solution. The anion exchange membrane could be reused.

PhotocatalyseIndex. décimale : 620.1 Mécanique de l'ingénieur (mécanique appliquée) et matériaux Résumé : Cette étude porte sur la fonctionnalisation par TiO2 d’une argile marocaine de type beidellite et sur l’évaluation de son activité photocatalytique pour l’élimination d’un colorant anionique : l’orange G (OG), utilisé dans l’industrie textile. Les échantillons argileux ont été caractérisés, avant et après fonctionnalisation, par DRX, MEB et MET couplé à l’analyse EDX, TG-ATD, FTIR, ICP et RMN du solide. La beidellite est aluminifère, dioctaédrique, de formule chimique (Si7,57Al0,43)8 (Al2,75Fe0,73Mg0,38Ti0,14)4 (Na0,37K0,23Mg0,01) avec une CEC, une surface spécifique et un volume poreux total de l’ordre de 48 méq/100 g, 72 m2/g et 0,128 cm3/g respectivement. Les matériaux argileux nanocomposites obtenus sont constitués de nanoparticules de TiO2 (taille moyenne 10 nm) supportées par les feuillets de la beidellite. Leurs surfaces spécifiques sont quasiment du même ordre de grandeur que celle de la beidellite tandis que leurs volumes poreux augmentent pour atteindre 0,226 cm3/g. L’échantillon calciné à 600 â—¦C, dans lequel TiO2 est sous forme d’anatase, manifeste une activité photocatalytique remarquable vis-à -vis de l’élimination de l’OG en milieu aqueux.
