For the adsorption of Pb(II)
and Cu(II) single heavy metals, we discovered that the adsorption
capacity of Spirogyra algae was significantly higher than that of
Cladophora algae. In comparing the characteristics of biomass,
FT-IR testing showed that functional groups were similar. However,
plant bodies of Cladophora spp. often have large amounts of
epiphytic algae, thus causing differences in adsorption volume.
Furthermore, differences in adsorption volume may be due to differences
in proteins, lipids, or the composition of other carbohydrates
affecting the number of adsorption sites. The differences
may be due to the epiphytic algae on Cladophora spp., which affects
the quality of algae powder production
