Hexavalent chromium removal from water by microalgal-based materials: Adsorption, desorption and recovery studies.

The current study presents a comprehensive comparison towards the potential of different microalgal-based materials for the removal of hexavalent chromium (Cr(VI)) from water. Among the tested materials, microalgal biochar showed the highest removal efficiency (100%) of Cr(VI). The highest monolayer estimated adsorption capacities were 23.

Effect of sodium selenite on the bacteria growth, selenium accumulation, and selenium biotransformation in .

In this study, the effect of low selenium concentrations on bacteria growth, selenium bioaccumulation, and selenium speciation in was investigated. Six different sodium selenite (NaSeO) solutions with concentrations of 0, 0.5, 1, 2, 3, and 4 mg/L were added in MRS broth for 24 h.
