iosorption of cadmium, lead and copper with calcium alginate xerogels and mmobilized Fucus vesiculosus

چکیده
This paper determines the effect of immobilized brown alga Fucus vesiculosus in the biosorption of heavy metals with alginate xerogels. Immobilization increased the kinetic uptakes and intraparticle diffusion rates of the three metals. The Langmuir maximum biosorption capacity increased twofold for cadmium, 10 times for lead, and decreased by half for copper. According to this model, the affinity of the metals vailable online 12 July 2008

Characterization of the biosorption of cadmium, lead and copper with the brown alga Fucus vesiculosus.
The recovery of cadmium, lead and copper with the brown alga Fucus vesiculosus was characterized and quantified. The biosorption data fitted the pseudo-second order and Langmuir isotherm models, but did not adjust to the intraparticle diffusion model. The metal uptakes deduced from the pseudo-second order kinetic model and the Langmuir isotherm model followed a similar sequence: Cu>Cd approxima...

Natural polymers widely used to produce drug carriers and active dressings include alginates, gelatine, chitosan and hyaluronic acid. In this study, alginate films were obtained bypassing the process of lyophilization. Produced from the common bladder wrack (Fucus vesiculosus L.), they can be used in food chemistry, wound treatment (tissue infections, burns) and in skin care; they are also good...
متن کاملALGAL BIOMASS FROM Fucus vesiculosus (Phaeophyta): INVESTIGATION OF THE MINERAL AND ALGINATE COMPONENTS
Mineral composition of algal biomass from Fucus vesiculosus (the Baltic Sea, Estonia) is rich in light elements (Mg, K, Ca, Na) and halogens (Br, I). Arsenic content is also high (over 300 ppm); the content of other toxic elements (Hg, Sb, Se, etc.) is extremely low. Mineralization of the algal whole biomass does not depend on seasonal varieties. The content of α-L-guluronic acid residues, and ...
متن کاملScreening of antifouling biocides around a pleasure boat marina in the Baltic Sea after legal restrictions.
Copper, zinc, and Irgarol 1051 concentrations were determined around a pleasure boat marina in the Stockholm Archipelago. Copper concentrations in water were twice as high (6.62 μg L⁻¹) in 2004 as 1992-1993, zinc concentrations six times higher (20.0 μg L⁻¹). Concentrations in bladder wrack (Fucus vesiculosus) had also risen. Irgarol concentrations in water were similar (~0.17 μg L⁻¹) in 1996 a...
متن کامل[Fucus vesiculosus induced hyperthyroidism in a patient undergoing concomitant treatment with lithium].
INTRODUCTION Fucus vesiculosus is a marine alga rich in iodine, which is being used in alternative medicine as a laxative, diuretic, and as a complement for weight loss diets. CASE REPORT We report the case of a 60-year old male patient, diagnosed with bipolar disorder and under treatment with lithium concomitantly with a herbal preparation, including Fucus vesiculosus, as a laxative. He deve...
