“…Heavy metals such as mercury, lead, cadmium, copper, chromium and nickel are extremely toxic even in minute quantities [1]. Chromium is more abundant in earth's crust and is widely used in electroplating, leather tanning, metal finishing and chromate preparation.…”

“…In recent years, various efforts have been focused on the immobilization of alga biomass, which is a potential way to overcome the disadvantages. Such supporting materials as alginate (Bayramoglu and Yakup Arıca, 2009;Mata et al, 2009), silica gel (Rangsayatorn et al, 2004), polyacrylamide and polyurethanes (Mehta and Gaur, 2005) were used for the biomass immobilization. However, metal uptake efficiency of immobilized cells is reportedly often much lower than that of raw biomass.…”

“…For example, the cadmium sorption capacity drops from 98 mg-Cd/g for the Spirulina platensis to 71 and 37 mg-Cd/g for the alginate and silica immobilized species, respectively (Rangsayatorn et al, 2004). Mata et al (2009) reported that the sorption capacity of alginate immobilized Fucus vesiculosus for copper was reduced nearly 60% due to immobilization. Synthetic polymers, such as polyacrylamide and polyurethanes, may be used for immobilization of biomass; the high cost and toxicity restrict their applications (Mehta and Gaur, 2005).…”

Improvement of metal adsorption onto chitosan/Sargassum sp. composite sorbent by an innovative ion-imprint technology

Ion-imprinted chitosan Sargassum sp. a b s t r a c tTechnology for immobilization of biomass has attracted a great interest due to the high sorption capacity of biomass for sequestration of toxic metals from industrial effluents.However, the currently practiced immobilization methods normally reduce the metal sorption capacities. In this study, an innovative ion-imprint technology was developed to overcome the drawback. Copper ion was first imprinted onto the functional groups of chitosan that formed a pellet-typed sorbent through the granulation with Sargassum sp.; the imprinted copper ion was chemically detached from the sorbent, leading to the formation of a novel copper ion-imprinted chitosan/Sargassum sp. (CICS) composite adsorbent. The copper sorption on CICS was found to be highly pH-dependent and the maximum uptake capacity was achieved at pH 4.7e5.5. The adsorption isotherm study showed the maximum sorption capacity of CICS of 1.08 mmol/g, much higher than the non-imprinted chitosan/Sargassum sp. sorbent (NICS) (0.49 mmol/g). The used sorbent was reusable after being regenerated through desorption. The FTIR and XPS studies revealed that the greater sorption of heavy metal was attributed to the large number of primary amine groups available on the surfaces of the ion-imprinted chitosan and the abundant carboxyl groups on Sargassum sp.. Finally, an intraparticle surface diffusion controlled model well described the sorption history of the sorbents. ª 2010 Elsevier Ltd. All rights reserved. IntroductionBiosorption has been considered as a promising technology for the removal of low-level toxic metals from industrial effluents and natural waters (Volesky, 2007;Mehta and Gaur, 2005;Wang and Chen, 2009). Marine algae have received greater attention because of their high metal biosorption capacity, low cost, and renewable nature. They can effectively remove heavy metal ions with concentrations ranging from few ppm to several hundreds ppm. The maximum metal biosorption capacity ranging from 0.1 to 1.5 mmol/g biosorbent has been reported (Davis et al., 2003; Yang, 2005, 2006 A v a i l a b l e a t w w w . s c i e n c e d i r e c t . c o m j o u r n a l h o m e p a g e : w w w . e l s e v i e r . c o m / l o c a t e / w a t r e s w a t e r r e s e a r c h 4 5 ( 2 0 1 1 ) 1 4 5 e1 5 40043-1354/$ e see front matter ª

“…With an increase of the atomic mass, there is a decrease in the so-called cation hydrodynamic beams, and by this their exchange energy is increasing [45]. On the basis of the conducted studies, the affinity columns of metals by sorption structures were determined, eg the alga Cyanidium caldarium: Zn > Mn > Ni > Cu [46], Caulerpa lentillifera: Pb > Cu > Cd > Zn [17], Fucus vesiculosus: Pb > Cu > Cd [47] and Chaetophora elegans: Ni > Zn > Pb > Cd [48]. The algae of the phyla: green algae (Chlorophyta: Caulerpa lentillifera, Chaetophora elegans) and brown algae (Phaeophyta: Fucus vesiculosus) are characterised by convergent affinity columns of heavy metals to their thalli.…”

Abstract:The publication is a synthetic collection of information on the sorption properties of marine and freshwater algae. Kinetics and sorption equilibrium of heavy metals in algae-solution system, influence of abiotic factors on the process of sorption and desorption of analytes from biomass are discussed. In paper the results of laboratory tests conducted using different species and types of algae, which purpose was to assess their usefulness as natural sorbents, are described. The conclusions drawn from current research confirm the results from literature.
