“…Kütz. to absorb copper (II) from aqueous solutions and showed that this alga was characterized by one of the highest adsorption capacities for Cu 2+ between others algal biosorbents [28]. Our studies confirmed the ability of Cladophora's effective copper biosorption, with the highest copper adsorption capacity of 8.5 mg g -1 , which corresponds to 0.13 mmol g -1 .…”

“…In this paper, the possibility of obtaining ecological components for cosmetic purposes by enriching the filamentous biomass of freshwater Cladophora with copper is also presented. Most of the literature sources concern the biosorption of copper (II) by marine Cladophora in wastewater treatment [27,28]. However, several studies have been conducted referring to the use of freshwater Cladophora as a biosorbent to remove copper (II) [26,29,30].…”

This study was undertaken to determine mineral content, amino acid and fatty acid composition of the freshwater macroalga -Cladophora glomerata. The studies were based on the content comparison in algal biomass collected from a lake and cultured in a laboratory. To determine the ability of copper cumulating by macroalgae, Cladophora was cultured in the medium supplemented with Cu ions. This study indicated that the relative abundance of metals in filaments decreased in the following order: Ca > K > Mg > Na > Fe > Cu > Zn > Pb > As > Ni > Cd > Mn > Cr > Co. Total protein content ranged from 14.45% in Cladophora from a lake to 26.55% in Cladophora from a laboratory. The main amino acids analyzed were aspartic and glutamic acid. The fatty acid content in the dry matter of the extract varied depending on the extraction method used: ethylene alcohol (19.0%), acetone (34.5%) or supercritical fluid extraction (62.5%). Freshwater C. glomerata due to the macrominerals, trace elements, amino and fatty acids composition in the extracts can be a valuable resource for nutritional and cosmetic applications.

“…A net negative charge formed by the carboxyl, hydroxyl, amino and sulphydryl groups on the cell surface confirms the high affinity for the binding of heavy metals (Deng et al, 2007;Gupta and Rastogi, 2008). The region between 1080 to 1040 cm -1 denotes the presence of SO 3 H in sulfonic acid.…”

The present study investigated the removal of toxic pollutants and reduction of heavy metals from tannery wastewater using Chlorella vulgaris. The physiochemical parameters like pH, electrical conductivity (EC), biological oxygen demand (BOD), chemical oxygen demand (COD), total solids (TS), total dissolved solids (TDS), chloride, total hardness (TH), bicarbonate, magnesium, ammoniacal nitrogen, phosphate and heavy metals (Cu, Cr, Zn, Ni and Fe) were analysed using standard methods. Functional group of toxic chemicals in tannery wastewater and C. vulgaris treated wastewater were analysed by Fourier transforms infrared spectroscopy (FT-IR) and gas chromatography -mass spectrometry (GC-MS). 20 to 60% of chemicals (bicarbonate, chloride, nitrogen, phosphate and magnesium) were reduced by the treatment using C. vulgaris within 28 days. FT-IR and GC-MS analysis reveals that the functional group of azo compounds was not in C. vulgaris treated wastewater. Thus, the results obtained conclude that C. vulgaris can be used as a suitable tool for the removal of toxic chemicals of tannery wastewater.

“…Basha et al [8] indican que la máxima captación de cobre (alrededor de 61 %) se produce en pH igual a 6 al utilizar la especie Cystoseira como biosorbente de iones de cobre y níquel. Por otro lado, los resultados alcanzados por Deng et al [21] al remover cobre utilizando Cladophora fascicularis, reportaron que en el rango de pH entre 4 y 5 se logran las mayores eliminaciones. Ellos indican que los grupos carboxílicos presentes en estas algas juegan un rol principal en la capacidad de adsorción de las algas.…”

ResumenSe realizaron experimentos de biosorción batch y en continuo para remover cobre desde soluciones acuosas usando como adsorbentes algas verdes y residuos de aceituna en condiciones vírgenes y activadas químicamente. Los resultados de la biosorción a escala batch indican que las algas presentan mayor capacidad de eliminación que los orujos, alcanzándose captaciones de cobre del orden de 96 % con algas activadas con disoluciones de Na 2 SO 4 bajo condiciones óptimas de las variables estudiadas. Los resultados de los ensayos en columna muestran que las algas vírgenes captan más iones cobre que las activadas con Na 2 SO 4 , con eficacias de eliminación del 98 % durante los primeros 20 min, con un tiempo de ruptura de 240 min y una saturación a los 600 min. Al ser sometidas a un segundo ciclo de biosorción, las algas regeneradas muestran un mejor rendimiento lo que indica que pueden ser usadas en otro ciclo de eliminación. Palabras claveBiosorción; Iones cobre; Activación; Biomasa. Biosorption of copper ions with biomass of algae and dehydrated waste of olives AbstractThey were carried out experiments of biosorción batch and in continuous to remove copper from aqueous solutions using as adsorbents green algae and olive residues under virgins conditions and chemically activated. The results of batch biosorption indicate that the algae present mayor elimination capacities than the waste of olives, with uptakes of copper of the order of 96 % using activated algae with dissolution of Na 2 SO 4 under the optimum conditions. The results of the columns tests show that the virgin algae permits the removal of more copper ions than the activate algae, with removal efficiency of 98 % during the firth 20 min, a breakthrough time of 240 min and a saturation at time of 600 min. In the second cycle the regenerated biomass showed a best performance indicating that they can be used for another biosorption cycle. KeywordsBiosorption; Coppers ions; Activation; Biomass. INTRODUCCIÓNLa actividad industrial y minera arroja al ambiente metales tóxicos como plomo, mercurio, cadmio, cobre, arsénico y cromo, muy perjudiciales para la salud humana y para la mayoría de las formas de vida. Estos metales pueden detectarse en el medio ambiente en su estado elemental lo que implica que no están sujetos a biodegradación o a formación de complejos salinos por lo que en estas circunstancias no pueden ser mineralizados [1] .Una vez emitidos, pueden permanecer en el ambiente durante cientos de años. La toxicidad de los metales pesados y su efecto en el ecosistema han generado en los últimos años un incremento considerable de estudios relacionados con la eliminación de estos elementos desde soluciones acuosas [2] .Teniendo en cuenta los efectos que provocan los metales pesados, es evidente que se hace necesaria su eliminación de los diversos efluentes. Las industrias se ven obligadas a reducir la cantidad y la peligrosidad de sus vertidos al medio ambiente, a causa de las presiones legales, sociales y econó-micas [2] .Normalmente, son utilizados di...
