Study of the kinetics of sorption of heavy metal ions by dry biomass of cyanobacteria

Abstract

Sorption of copper (II), lead (II) and cadmium ions from a solution with a concentration of 1 ∙ 10-4 mol/L by dry biomass of cyanobacteria Fischerella muscicola occurred 1.4-1.9 times faster than Nostoc paludosum. The sorption rate of lead and copper ions was 1.9-2.6 times higher compared to cadmium ions.
