Application of zeolite-Arthrobacter viscosus system for the removal of heavy me...
Rosales, E.; Pazos, M.; Sanromán, M. A.; Tavares, M. T.A hybrid system combining the ion-exchange properties of a NaY zeolite and the characteristics of the bacterium Arthrobacter viscosus was investigated to treat polluted effluents with dye and toxic metals. In this study, the dye and the metal ion employed were a thiazine dye, Azure B, and chromium (VI), respectively. Initially, the removal of dye by the zeolite was tested. The analysis of dye equilibrium isothe...
Biosorption of heavy metal and dyes : a promising technology leather wastewater...
Rosales, E.; Pazos, M.; Sanromán, M. A.; Tavares, M. T.The presence of dyes and heavy metals is usual in industrial processes like chrome tanning in tannery industry and their removal may be an environmental problem. Different techniques were developed and applied for the treatment of dyes and heavy metals in effluents. Among them, adsorption showed to be an economic, simple operation and an effective technique. Zeolites have a strong affinity for cations of transi...
