Biosorption of Cadmium by the Protonated Macroalga Sargasssum Muticum: Binding Analysis With a Non-Ideal, Competitive and Thermodynamically Consistent Adsorption (NICCA) Model
Lodeiro, Pablo; Rey-Castro, Carlos; Barriada, José Luis; Sastre de Vicente, Manuel; Herrero, Roberto (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) ... -
Gibbs-Donnan and Specific Ion Interaction Theory Descriptions of the Effect of Ionic Strength on Proton Dissociation of Alginic Acid
Rey-Castro, Carlos; Herrero, Roberto; Sastre de Vicente, Manuel (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 ... -
Interactions of Cadmium(II) and protons with dead biomass of marine algae Fucus sp
Herrero, Roberto; Cordero Pérez, Bruno; Lodeiro, Pablo; Rey-Castro, Carlos; Sastre de Vicente, Manuel (2005-11-09)[Abstract] Samples of dead biomass from the marine brown algae Fucus ceranoides, F. vesiculosus and F.serratus were studied for their ability to remove cadmium from aqueous solutions. The metal sorption process is rapid, ... -
Removal of Inorganic Mercury From Aqueous Solutions by Biomass of the Marine Macroalga Cystoseira Baccata
Herrero, Roberto; Lodeiro, Pablo; Rey-Castro, Carlos; Vilariño, Teresa; Sastre de Vicente, Manuel (Elsevier, 2005)[Abstract] The ability of Cystoseira baccata algal biomass to remove Hg(II) from aqueous solutions is investigated. The mercury biosorption process is studied through batch experiments at 25ºC with regard to the influence ...
