Abstract

The main goal of the present work is to show the possibility of using the biomass Spirulina subsalsa, Saccharomyces cerevisiae, dry yeast and chitin-glucan yeast complex to remove heavy metals from sewage. It was found that Spirulina subsalsa and Saccharomyces cerevisiae have the greatest ability to concentrate heavy metals (Zn, Cu and Ni). The article presents data on the influence of the concentration of biomass, the index of hydrogen ions (pH) and temperature on the sorption activity of the investigated biosorbents. The maximum removal of heavy metals was recorded at 20—29 °C with a neutral pH (8.0) in the first 24 hours.

Keywords
