Tea waste as a low cost adsorbent for the removal of Cu and Pb from wastewater
TL;DR: In this article, the adsorption of copper and lead ions onto tea waste from aqueous solutions was studied to enable comparison with alternative commonly available absorbents, and the equilibrium data were satisfactorily fitted to Langmuir and Freundlich isotherms.

Sargassum seaweed as biosorbent for heavy metals.
TL;DR: In this paper, six different species of non-living Sargassum biomass were compared on the basis of their equilibrium Cd and Cu uptake in order to evaluate potential variability in the sorption performance of different Sargasum species.

Removal and recovery of lead using nonliving biomass of marine algae.
TL;DR: The lead uptake capacity of Sargassum biomass was constantly retained (98%) and no significant biomass damage took place after 10 sorption-desorption cycles, and the applicability of the Langmuir and Freundlich models for the different biosorbents was tested.

Biosorption of cadmium(II) from aqueous solutions by pre-treated biomass of marine alga DurvillAea potatorum
TL;DR: In this paper, the adsorption capacity of pre-treated biomass of D. potatorum was investigated and it was shown that pre-treatment of the native biomass with calcium chloride and subsequent thermal treatment considerably improved the swelling properties and physical stability of the biomass granules.
