This study discovered that the adsorption effects of Spirogyra
spp. for Pb(II) and Cu(II) are superior to those of Cladophora spp.
FT-IR analysis indicated that the functional groups of these two
genera of algae are similar, but varied in their adsorption efficiency.
This may be due to the differences in protein, lipid, or other
carbohydrate content of the two genera of algae. Furthermore,
whether large amounts of epiphytic algae on Cladophora plant
bodies affect subsequent algae powder manufacturing and adsorption
results warrants further study. Continuing adsorption–desorption
experiments have discovered that both types of biomass are
excellent biosorbents with potential for further development.
