Biosorption of Cadmium by Biomass of Brown Marine Macroalgae
(2005-11-07)[Abstrac] Five different brown seaweeds, Bifurcaria bifurcata, Saccorhiza polyschides, Ascophyllum nodosum, Laminaria ochroleuca and Pelvetia caniculata were studied for their ability to remove cadmium from aqueous solution. ... -
Biosorption of Cadmium by the Protonated Macroalga Sargasssum Muticum: Binding Analysis With a Non-Ideal, Competitive and Thermodynamically Consistent Adsorption (NICCA) Model
(Elsevier, 2005)[Abstract] Protonated biomass of the seaweed Sargassum muticum was investigated for its ability to remove cadmium(II) from aqueous solutions. In this work, a non-ideal, semi-empirical, thermodynamically consistent (NICCA) ... -
Physicochemical Studies of Cadmium(II) Biosorption by the Invasive Alga in Europe, Sargassum Muticum
(Wiley Interscience, 2004)[Abstract] In recent years, there has been a significant increase in the studies concerning brown seaweed as biosorbents for metal removal owing to their high binding ability and low cost. This work reports the results of ... -
Gibbs-Donnan and Specific Ion Interaction Theory Descriptions of the Effect of Ionic Strength on Proton Dissociation of Alginic Acid
(Elsevier, 2004)[Abstract] The apparent proton dissociation constants of a commercial alginic acid have been obtained in KNO3 and NaCl at concentrations ranging between 0.01 and 2 mol·L-1. An analysis of the dependence on the ionic strength ... -
Kinetic and Equilibrium Study of the Reaction of Nitroprusside and Hydroxide Ions: Influence of Ionic Strength Using Pitzer Model
(Wiley Interscience, 2004)[Abstract] A kinetic and equilibrium study of the addition reaction of hydroxide ions to nitroprusside has been carried out in this paper. Rate and equilibrium constants at different salt concentrations (up to 4 mol/kg) ...
