Abstract: Biomass of nonliving brown seaweed Sargassum fluitans pretreated by different methods is capable of taking up more than 10% (11 mEq/g) of its dry weight in aluminum at pH 4.5. There are indications that the biomass hydroxyl groups were involved in sequestering the aluminum in the form of polynuclear aluminum species. Aluminum-alginate complex (like cotton candy) was formed in the aluminum...
The sorption of cadmium by biomass of brown marine alga Sargassum fluitans has been studied in a standard mixed batch reactor at steady-state and transient conditions. Steady-state sorption data over the temperature range of 7°C to 60°C indicated a higher cadmium uptake at elevated temperatures. Overall adsorption rates also slightly increased with increasing temperature in the range of 20°C to...
