“…The experimental data were best fitted to this model for all adsorbent materials having correlation coefficient values over 0.99 for both composites; however, the correlation coefficient for Fe-Ni nanoscale oxides was 0.934. Similar results were obtained by Gutiérrez-Segura et al (2009) …”

“…Slejko (1985), implying, nevertheless, a heterogeneous surface structure. These values can be compared with those where Fe-zeolitic tuff (n=0.66) and carbonaceous material from pyrolyzed sewage sludge treated with HCl (n=0.36) were used by Gutiérrez-Segura et al (2009) and to those where activated sewage sludge (n=0.121) and pyrolyzed sewage sludge (0.116) were employed by Otero et al (2003). The Langmuir-Freundlich isotherm is a combination of Langmuir and Freundlich models.…”

“…Recently, numerous approaches have been studied for the development of cheaper and effective adsorbents. Many non-conventional low-cost adsorbents, including natural materials, biosorbents and waste materials from industry and agriculture, have been proposed by several researchers (Crini 2006;Gupta and Suhas 2009;Gutiérrez-Segura et al 2009;Otero et al 2003;Torres-Pérez et al 2008;Trujillo-Reyes et al 2010;Wang et al 2008). On the other hand, metallic nanoparticles are beginning to receive more attention because of their relatively higher chemical activity and specificity of interaction.…”

Novel adsorption materials-Fe-Ni nanostructures and C/Fe-Ni composites-with the carbonaceous material coming from sewage sludge, have been developed and evaluated to remove indigo carmine from aqueous solution. The adsorbents were characterized by transmission and scanning electron microscopy, X-ray powder diffraction, IR spectroscopy and BrunauerEmmett-Teller analysis. Sorption kinetics and isotherms were determined and the adsorption behaviours analysed. All adsorbents here studied have exhibited good efficiency to remove indigo carmine from aqueous solution. Pseudo-second-order kinetic and LangmuirFreundlich isotherm models were successfully applied to the experimental data. Fe-Ni nanostructures adsorption capacity was 977.18 mg/g, followed by C/Fe-Ni 75/25% composite with 654.33 mg/g, and a lowest value, 486.41 mg/g, was obtained for C/Fe-Ni 95/5% composite. It can be suggested that the sorption mechanism of the dye is chemisorption on these heterogeneous novel, cheap and efficient functional materials. All materials provide the highest adsorption capacities in pH between 4 and 10. In addition, three sorption-desorption cycles using 30% H 2 O 2 solution and distilled water were performed; sorption efficiencies of both composites (C/FeNi 75/25% and C/FeNi 95/5%) decreases in each cycle, but this behaviour is not observed for FeNi nanoscale oxides.

Abstract:The role of fungi in the treatment of wastewater has been extensively researched. Many genera of fungi have been employed for the dye decolourization either in living or dead form. In this study, the removal of an acidic dye, Indigo Carmine (IC), from an aqueous solution by biosorption on dead fungus, Pleurotus ostreatus, was investigated. The effects of contact time, initial dye concentration, amount of dead biomass, agitation rate and initial pH on dye removal have been determined. Experimental results show that an increase in the amount of dead biomass positively affected the dye removal. The highest removal was obtained at 150-200 rpm. Slightly lower removing activities were found at lower agitation rates. The dye adsorption effi ciency was not affected by pH except minor variation in the pH of 2-8. Color removal was observed to occur rapidly within 60 minutes. The removal of dye by dead biomass of P. ostreatus was clearly dependent on the initial dye concentration of the solution. Dye removal was reduced from 93% to 64% as concentration was increased from 50 to 500 mg/L Indigo Carmine. This study showed that it was possible to remove textile dyes by dead biomass of P. ostreatus.
