DECOLORIZATION OF REMAZOL BLUE AND REMAZOL RED USING ASPERGILLUS NIGER ISOLATED FROM TEXTILE WASTEWATER

The paper reports on the photocatalytic efficiency ofTiO2nanoparticles immobilized on polyvinyl pyrrolidone/acrylic acid (PVP/AAc) copolymer hydrogels, which are prepared by means ofγ-rays induced homo- and copolymerization. The efficiency of immobilized photocatalyst is tested on a commercial textile dye namely Remazol Red RB-133. The results are compared with photocatalytic efficiencies of different types of non supportedTiO2photocatalysts such as aqueous slurries of colloidalTiO2prepared by sol-gel technique, and commercially available Degussa P25. Although less efficient than nonsupported ones, the hydrogel supportedTiO2photocatalyst has the practical advantages of easy separation and removal from the reactors. This makes it a viable technique for the safe disposal of textile wastewater into the water streams.

This study evaluates the removal of textile dyes using mixed adsorbents prepared by the growth of Aspergillus niger in orange peels. The highest azo dye removal efficiency was obtained at pH 2, solid: liquid ratio (1: 4 g·mL-1) and time of equilibrium of 250 minutes for each dye. The concentrations of Remazol Black B (RB) and Remazol Red (RR) in both synthetic textile effluents were between 25 mg·L-1 and 100 mg·L-1. The mixed adsorbent was characterized by X-ray diffraction (XRD), spectroscopy infrared region (FTIR) and scanning electron microscopy (SEM). The results indicated that there was a 100% removal of RB and 94.85% of RR at the concentration of 25 mg·L-1. At the concentration of 100 mg·L-1, the percentages of removal reached 98.87% for RB and 96.37% for RR, respectively. The proposed mixed adsorbent was able to remove the textile dyes, presenting adsorptive capacities of 20.77 mg·g-1 and 19.28 mg·g-1 for the dyes RB and RR. Regarding the adsorption kinetics, the experimental data showed that the pseudo second order model was the one that best explained the adsorptive process. For the equilibrium results, the Langmuir model and the Langmuir-Freundlich model were the ones that best fit the experimental data of RB and RR, respectively. The mixed adsorbent produced is a promising alternative for the treatment of textile effluents.

O descarte de efluentes têxteis não tratados nos meios aquosos pode ocasionar em um rápido esgotamento do oxigênio dissolvido, o que resulta em um desequilíbrio noecossistema. São vários os métodos utilizados na remoção de cor, e, dentre eles, a adsorção vem se mostrando como um método de tratamento simples, barato e eficiente. O objetivo deste trabalho consiste em avaliar a habilidade da biomassa mista de Aspergillus niger e capim elefante (Penissetum purpureum Schum) na remoção do corante Remazol Vermelho de uma solução aquosa sintética sob difrentes condições de temperatura (30, 40 e 50 °C), concentrações variando entre 25 e 105 mg/L, tempo de adsorção de 0 a 200 minutos e pH 2.0. O estudo cinético foi caracterizado pelo modelo de pseudo-segunda ordem. Já o modelo de Langmuir se mostrou o melhor ajuste linear das isotermas de adsorção, apresentando uma capacidade de adsorção de 3,42 mg g-1. A esponteneidade da reação de adsorção foi avaliada através daenergia lvire de Gibbs. O estudo termodinâmico indicou que a adsorção é favorável e espontânea, além de que o aumento da temperatura ocasiona em uma redução na capacidade de adsorção. Estes resultados obtidos em efluentes sintéticosdemonstram que o adsorvente misto produzido neste estudo é uma alternativa promissora no tratamento de efluentes contaminados com Remazol Vermelho.

Influence Of Ph

The economic growth of the textile sector in Brazil has contributed to the generation of new jobs, qualification of the workforce and better living conditions for the population. However, due to the high activity of the sector, large volumes of toxic effluents have been generated which, if improperly disposed of, cause serious environmental damage. Therefore, alternatives in the treatment of effluents are interesting to increase the availability of this resource. A technique that has stood out, for being efficient, easy to operate and economical, is adsorption, a passive capture process where pollutants are deposited on the surface of materials. Thus, the work aimed to carry out a comparative study of the influence of pH in the removal of the dyes Remazol Black (RB), Remazol Red (RR) and Remazol Yellow (RGY) using different mixed adsorbents constituted by the fungus Aspergillus niger grown in orange peel in two different culture media. Six types of adsorbents (three for each culture medium) were produced and were treated with acid, base and without treatment. These were subjected to adsorption tests at different pHs (2, 7 and 9), using a solution (25 mg.L-1) volume of 100 mL, 0.5 g of biomass, rotation 150 rpm, 30 oC. The results showed that the adsorbents produced were able to adsorb the dyes RB, RGY, RR at different pHs. The best adsorption condition was obtained at pH 2 and the adsorbents were treated with acid, showing a promising alternative for the treatment of textile effluents.
