    Bioaccumulation of rubidium (Rb+) and lithium (Li+) from alkaline wastewater containing 480 mg L−1 Rb+ and 540 mg L−1 Li+, a by-product of zinnwaldite processing, was studied at laboratory scale using growing freshwater microalgae (Chlorella vulgaris, Desmodesmus quadricauda and Scenedesmus obliquus). Bioaccumulation of Li+ was very low, while the bioaccumulation of Rb+ was significant by all tested strains. The best result was found for C. vulgaris, which accumulated 54% of the original amount of rubidium in growth media (48 mg L−1) within 4 days. In addition, the wastewater did not affect the growth rate of C. vulgaris. The effect of potassiun (K+) concentration on total bioaccumulation of alkali metal ions and its selectivity by C. vulgaris was also tested. The highest K+ concetration (334 mg L−1) resulted in bioaccumulation of 4.3 mg Rb+ per gram of biomass with Rb+:Li+ uptake ratio of 26.9. By decreasing the K+ concetration in medium (56 mg L−1), the total bioaccumulation improved (4.70 Li+ per gram of biomass, 5.93 Rb+ per gram of biomass) but at the cost of lower selectivity (Rb+:Li+ uptake ratio 1.3). These findings have a potential of practical utilization, as both Rb+ and Li+can be recovered from biomass by incineration and subsequent chemical separation.
