Treatment of Rhenium-Containing Effluents Using Environmentally Friendly Sorbent, Saccharomyces cerevisiae Biomass.

ABSTRACT: Yeast Saccharomyces cerevisiae biomass was applied for rhenium and accompanying elements (copper and molybdenum) removal from single- and multi-component systems (Re, Re-Mo, Re-Cu, and Re-Mo-Cu). Yeast biomass was characterized using X-ray diffraction, scanning electron microscopy, and Fourier transform infrared spectroscopy. The effects of biosorption experimental parameters such as solution pH (2.0-6.0), rhenium concentration (10-100 mg/L), time of interaction (5-120 min), and temperature (20-50 °C) have been discussed in detail. Maximum removal of rhenium (75-84%) and molybdenum (85%) was attained at pH 2.0, while pH 3.0-5.0 was more favorable for copper ions removal (53-68%). The Langmuir, Freundlich, and Temkin isotherm models were used to describe the equilibrium sorption of rhenium
