The effect of inhibitor concentration, temperature, and concentration of the corrosion medium on the inhibitor action was investigated. The surface morphology of the metal surface was investigated by scanning electron microscopy (SEM). The inhibition efficiency increased with the increase in the concentration of the inhibitor, but decreased with the increase in temperature. Both thermodynamic and kinetic parameters were calculated and discussed. The adsorption of MAMT on the base alloy was found to be through physisorption, obeying Langmuir’s adsorption isotherm. The results obtained from both the techniques were in good agreement with each other.

The adsorption, diffusion and fixation of this dye on cotton fabric in Triton X-100 reverse micelle and bulk water were then investigated. The equilibrium and kinetic data of the dye adsorption process were evaluated. The colour strength and fixation rate of cotton fabrics dyed in the micelle and in bulk water were also examined and compared. The results indicated that the amount of dye adsorbed increased with the increasing temperature and the initial dye concentration. The dye adsorption process could be described using the Langmuir isotherm and pseudo-second-order kinetic equations. It was found that CI Reactive Red 195 showed a stronger adsorption property on cotton fabric in Triton X-100 reverse micelle than in bulk water without the addition of sodium chloride. Using Triton X-100 reverse micelle as the dyeing medium offered the reactive dye better diffusion performance within the cotton fibre as compared with bulk water. Moreover, higher fixation of the dyes absorbed on the cotton fibre was achieved when the optimum concentration of sodium carbonate was used as the alkali agent in Triton X-100 reverse micelle.

The results indicated that the prepared carbon black/latex dispersion had excellent freeze–thaw stability. Cotton fabric that was cationised with 3 g/l of 3-chloro-2-hydroxypropyltrimethyl ammonium chloride at a liquor ratio of 30:1 can be optimally dyed with 4% owf carbon black/latex under the conditions of pH 7.2, 60 °C, and 1 h. The adsorption behaviour of the carbon black/latex towards cationised cotton fabric followed the Langmuir adsorption isotherm, with a lower dyeing rate and a better colour levelness than the ordinary carbon black dispersion with binder.

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 ionic and nonionic surfactants on hydrophobic pigment in aqueous medium / Hikmet Sis in COLORATION TECHNOLOGY, Vol. 128, N° 3 (2012)

[article]  inCOLORATION TECHNOLOGY > Vol. 128, N° 3 (2012) . - p. 244-249 Titre : Adsorption characteristics of ionic and nonionic surfactants on hydrophobic pigment in aqueous medium Type de document : texte imprimé Auteurs : Hikmet Sis, Auteur ; Mustafa Birinci, Auteur Année de publication : 2012 Article en page(s) : p. 244-249 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Adsorption Colorants -- Adsorption Hydrophobie Nonylphenol éthoxylates Oléate de sodium Phtalocyanine de cuivre Potentiel zeta Surfactants Index. décimale : 667.3 Teinture et impression des tissus Résumé : The current study is based on the investigation of the adsorption properties of ionic and nonionic surfactants on an organic hydrophobic pigment powder, namely, β-copper phthalocyanine, in aqueous medium. The nonionic surfactants, selected systematically to represent varying degrees of ethoxylation, are nonylphenol ethoxylates, whereas the ionic surfactant is sodium oleate, a carboxylate-type anionic reagent. The adsorption of surfactants was assessed qualitatively by surface analysis of powders, before and after the adsorption of the surfactants. The experimental results were explained by the structural and other properties of the surfactants and the surface properties of the pigment. The specific adsorption of surfactants on pigments was verified by zeta potential measurements, as they altered the zeta potential values to a great extent. Nonionic surfactants decreased the absolute value of the zeta potential of the powder; whereas anionic surfactant sodium oleate shifted the zeta potential to more negative values. On the one hand, Fourier Transform–infrared and X-ray diffraction examinations of the pigments did not show any noticeable evidence for surfactant untreated or treated copper phthalocyanine. On the other hand, thermal analysis (both thermogravimetric and differential thermal analysis) showed clear evidence of the surfactants on both pigments, as substantial changes in thermogravimetric curves were assessed.
