Abstract

|
|
Investigated the biosorption performances of copper by the immobilized biomass of nonliving marine brown alge h. fusiformis by each of the Ca-alginate method(Ca-ALG), Ba-alginate method(Ba-ALG), polyethylene glycol method(PEG), and carrageenan method (CARR). The copper removal performance increased but the copper uptake decreased as the biomass amount was increased. However, the copper uptake by the immobilized biomass increased with increasing initial copper concentration. The copper uptake by the immobilized biomass of the immobilization method decreased in the following sequence; Ca-ALG>Ba-ALG>PEG>CARR among the immoblization emthods. The copper uptake by the immobilized biomass followed the Langmuir isotherm better than the Freundlich isotherm.
