Adsorption, biosorption and bioaccumulation used to remove chromium (III) from tanning wastewaters : A critical review / B. H. Hintermeyer in JOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC), Vol. 97, N° 6 (11-12/2013)

Tannage Résumé : Processes of adsorption, biosorption and bioaccumulation were analyzed considering their ability to remove chromium(III). Already published studies that represent the actual state of knowledge were taken into account for this purpose. The review includes a detailed description of principal physicochemical properties of adsorbents, biosorbents and micro-organisms, pointing out those features that explain the mechanism by which the separation occurs. We noted an inadequate evaluation of the bearing species of the tanning agent with respect to treated solutions and that, not always the most adequate species was selected. In order to elucidate both aspects, the way in which the electrical charge and the size of studied complex ions affect the attraction force in adsorption/biosorption were examined. The consideration of such parameters proved that the electrical charge varies enormously from one substance to another and besides it prevails on the size. Accordingly, it was decided to focus attention only on treatments that were performed with tanning wastewater or with basic chromium(III) sulphate. Finally, the amounts of chromium(III) sequestered per gram of each adsorbent/biomaterial were compared. The largest uptake was 189.1mg/g, obtained with a Cr-resistant autochthonous fungus.

Adsorption characteristics of CI Basic Blue 3 from aqueous solution onto Aleppo pine-tree sawdust / Naima Ouazene in COLORATION TECHNOLOGY, Vol. 128, N° 1 (2012)  

[article]  inCOLORATION TECHNOLOGY > Vol. 128, N° 1 (2012) . - p. 21-27 Titre : Adsorption characteristics of CI Basic Blue 3 from aqueous solution onto Aleppo pine-tree sawdust Type de document : texte imprimé Auteurs : Naima Ouazene, Auteur ; Azzedine Lounis, Auteur Année de publication : 2012 Article en page(s) : p. 21-27 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Absorbants et adsorbants Colorants -- Adsorption Pin d'Alep Sciure de bois Solutions aqueuses (chimie) Index. décimale : 667.3 Teinture et impression des tissus Résumé : Aleppo pine-tree sawdust, a forest waste abundantly available in Algeria, was used for the adsorption of CI Basic Blue 3 from an aqueous solution. The effects of adsorbent dosage, pH, adsorbate concentration and contact time were studied. The equilibrium adsorption data were analysed by Langmuir, Freundlich and Temkin isotherm models. It was found that the Langmuir isotherm fitted well to the observed data for CI Basic Blue 3 adsorption onto Aleppo pine-tree sawdust based on the correlation coefficient R2 and four different error functions for the non-linear regression. The adsorption capacity of Aleppo pine-tree sawdust for CI Basic Blue 3 was determined with the Langmuir model and was found to be 65.36 mg g−1 at 293 K. The adsorption kinetic data were modelled using the pseudo-first-order, pseudo-second-order and intraparticle diffusion kinetic equations. It was seen that the pseudo-second-order equation could describe the adsorption kinetics and intraparticle diffusion was not the sole rate-controlling factor. The results indicated that Aleppo pine-tree sawdust is an attractive alternative for removing cationic dyes from wastewater.

Adsorption equilibrium studies of a simulated textile effluent containing a wool reactive dye on gallinaceous feathers / Olga M. Freitas in COLORATION TECHNOLOGY, Vol. 132, N° 5 (10/2016)  

[article]  inCOLORATION TECHNOLOGY > Vol. 132, N° 5 (10/2016) . - p. 421-430 Titre : Adsorption equilibrium studies of a simulated textile effluent containing a wool reactive dye on gallinaceous feathers Type de document : texte imprimé Auteurs : Olga M. Freitas, Auteur ; Lilita M. Moura, Auteur ; Sonia A. Figueiredo, Auteur ; Maria T. Pessoa de Amorim, Auteur Année de publication : 2016 Article en page(s) : p. 421-430 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Absorbants et adsorbants Colorants -- Adsorption Colorants réactifs Déchets -- Valorisation Eaux usées -- Analyse Eaux usées -- Epuration Plumes Index. décimale : 667.3 Teinture et impression des tissus Résumé : Gallinaceous feathers (from Gallus gallus domesticus, strains Cobb 500 and Label) were used as adsorbent for colour removal from a simulated textile effluent containing a wool reactive dye, the Yellow Lanasol 4G (CI Reactive Yellow 39). A brief chemical and physical characterisation of feathers was performed. Equilibrium studies at different selected temperatures, in the range 10–60 °C, were carried out. The equilibrium data were analysed using the Freundlich and Langmuir isotherm models. Adsorption capacity strongly increases with temperature. A maximum adsorption capacity of around 300 mg g?1 was obtained for Gallus gallus feathers, strain Cobb 500, at 60 °C, while for strain Label, 200 mg g?1 was obtained at 50 °C. For each type of feather a generalised model, valid for a given temperature range, was obtained. The isosteric heat of adsorption calculated was positive, so the mechanism involved in the adsorption process should correspond to endothermic chemisorption. This study provides important information concerning the use of gallinaceous feathers without any chemical treatment for colour removal from real textile wastewaters. The results in this study indicated that gallinaceous feathers, when compared with activated carbon, open promising perspectives concerning their utilisation for colour removal from textile effluent discharged at high temperatures; moreover, it would be an alternative for the valorisation of this waste.
