Resumo: | Textile industries remarkably present high consumption of water and elevated generation of wastewater. In most cases, these effluents are contaminated with a large amount of dyes, requiring previous treatment to disposal in the receiving bodies of water like rivers and lakes, or prior to its reutilization in the industry. The aim of this study was to evaluate the adsorption potential of tilapia (Oreochromis niloticus) scales of the reactive blue 5G dye and characterize this potential sorbent material, since it is an abundant waste of fish slaughterhouses of the western region of Paraná. For this purpose, characterization of the scale were carried out by OM, SEM, EDS, N2 physisorption, XRD, pHZPC, FTIR and FT-Raman. Experiments were performed in closed batch system to examine the effect of the particle diameter (6, 16, 32, 100, 150, 325 mesh and base), the adsorbent mass (0.1, 0.2 and 0.3 g), initial pH of the dye solution (2.0, 7.5 and 10.0) and the chemical pretreatment at the scales adsorption capacity. Finally, equilibrium assays were performed at the optimum conditions obtained. Further experiments were performed at fixed bed continuous system, the breakthrough curves were carried at different particle diameters (12, 16, 32 mesh and granulometric mixture) and under different pH values of the feed solution (2.0, 5.5, 7.5 and 10). Furthermore, the influence of treatment chemical adsorption was also studied. Moreover, the amount of dissolved organic carbon was measured during the adsorption process to examine the possibility of lixiviation. The material characterization indicated low incidence of pores on the scale surface, and the presence of chemical groups characteristic of collagen and hydroxyapatite. PHZPC analysis demonstrated that the point of zero charge of the scale was 7.64. At the both batch and column adsorption process higher values of adsorption capacity was reached by using the particle sizes 6, 16 and 32 mesh, at initial pH 2.0. The chemical treatment did not present any influence at the adsorbent adsorption capacity. Langmuir and Radke-Prausnitz isotherms best represented the equilibrium data of batch process. For the fixed bed process assays, the largest adsorption capacity was achieved by using the granulometric mixture of scales, at pH 2.0, at these conditions the highest adsorption capacity reached was q = 394.8 mg g-1, achieving a breakthrough time of tb = 20.5 h at the feed concentration of 75 mg L-1. The dissolved organic carbon amount increased during the experiment due to the dye solution concentration rise. Considering the high removal levels and the low cost of the material, tilapia scale present a potential use as alternative adsorbent. |

Neste sentido, o objetivo deste trabalho foi avaliar o potencial de adsorção da escama do peixe Oreochromis niloticus (Tilápia) utilizando o corante reativo Azul 5G e caracterizá-la, visto que se trata de um resíduo abundante das indústrias frigoríficas de peixes da região oeste do Paraná. Para tanto, a caracterização da escama foi realizada pelas técnicas de MO, MEV, EDS, Fisissorção de N2, DRX, pHPCZ, FT-IR e FT-Raman. Foram realizados experimentos em sistema fachado e batelada para avaliar o efeito do diâmetro das partículas (6, 16, 32, 100, 150, 325 mesh e fundo), da massa de adsorvente (0,1, 0,2 e 0,3 g), do pHinicial da solução de corante (2, 7,5 e 10) e do pré-tratamento químico na capacidade de adsorção das escamas. Por fim, realizou-se experimentos de equilíbrio nas melhores condições avaliadas. Também foram obtidas as curvas de ruptura em leito fixo sob diferentes granulometrias (12, 16, 32 mesh e mistura granulométrica), diferentes condições de pH da solução de alimentação (2, 5,5, 7,5 e 10) e de concentração da solução de alimentação. Avaliou-se ainda a influência do pré-tratamento químico no adsorvente e a quantidade de carbono orgânico dissolvido durante o processo de adsorção para verificar a ocorrência de lixiviação. A caracterização indicou baixa quantidade de poros na superfície da escama, além de grupamentos químicos característicos de colágeno e hidroxiapatita. A análise de pHPCZ indicou que o ponto de carga zero da escama é 7,64. Em ambos os sistemas a maior capacidade de adsorção foi alcançada nas granulometrias 16 e 32 mesh e pHinicial 2, onde não foi verificada a influência do pré-tratamento químico no processo de adsorção. As isotermas que melhor se ajustaram aos dados de equilíbrio para o sistema fechado e batelada foram a de Langmuir e Radke-Prausnitz. Nos ensaios em leito fixo, a maior capacidade de adsorção foi obtida nas condições de mistura granulométrica das escamas e no pH 2,0, alcançando-se uma capacidade de adsorção de q = 394,8 mg g-1 para a concentração de 75 ppm e com um tempo de ruptura de tb = 20,5h. A carga de carbono orgânico dissolvido aumentou no decorrer do experimento devido ao aumento da concentração da solução de corante, a qual também não foi influenciada pelo pré-tratamento químico. Dado o elevado teor de remoção e o baixo custo do material, verifica-se que a escama de tilápia é um adsorvente alternativo em potencial.Made available in DSpace on 2017-07-10T18:08:04Z (GMT).
