          Abstract

          RESUMEN El presente trabajo evaluó la tecnología bioadsorción para la remediación de las aguas de La Laguna Azul, en el Cobre en Santiago de Cuba con alto contenido de iones metálicos, empleando la biomasa de caña de azúcar. Para esto, se realizó la caracterización de dos estaciones de monitoreo situadas a los extremos del reservorio acuático. En los análisis se demostró que el agua de la misma no cumple con las regulaciones de la NC: 1021-2014 “Higiene comunal: Fuentes de abastecimiento de agua. Calidad y protección sanitaria”. Los experimentos de adsorción demostraron que la biomasa utilizada en una matriz real es capaz de remover el 5,31 % de Mn2+ en condiciones naturales, el 33,36 % una vez tratada con NaOH y el 58,42 % bajo tratamiento con H3PO4, a un valor de pH de 4,3 y una masa de adsorbente de 0,5 g/50mL.

          ABSTRACT The present work, bioadsorption technology was evaluated for the remediation of the waters from “La Laguna Azul”, in the town of El Cobre in Santiago de Cuba with a high content of metal ions, through the use of sugar cane biomass. For this, the characterization of two monitoring stations located at the ends of the aquatic reservoir as carried out. In the analyses it was demonstrated that the water of the same one does not fulfill the regulations of the NC: 1021-2014 “Communal Hygiene. Sources of water supply: Quality and sanitary protection”. The adsorption experiments led to the biomass used in a real matrix being able to remove 5,31 % of Mn2+ ions under natural conditions, 33,36 % once treated with sodium hydroxide and 58,42 % under treatment with phosphoric acid, pH value of 4,3 and a mass of adsorbent of 0,5 g/50mL.

              Removal of lead from aqueous solution by activated carbon prepared from Enteromorpha prolifera by zinc chloride activation.

              Activated carbon was prepared from Enteromorpha prolifera (EP) by zinc chloride activation. The physico-chemical properties of EP-activated carbon (EPAC) were characterized by thermal stability, zeta potential and Boehm titration methods. The examination showed that EPAC has a porous structure with a high surface area of 1688 m(2)/g. Batch adsorption experiments were carried out to study the effect of various parameters such as initial pH, adsorbent dosage, contact time and temperature on Pb(II) ions adsorption properties by EPAC. The kinetic studies showed that the adsorption data followed a pseudo second-order kinetic model. The isotherm analysis indicated that the adsorption data can be represented by Freundlich isotherm model. Thermodynamic studies indicated that the adsorption reaction was a spontaneous and endothermic process. Copyright © 2010 Elsevier B.V. All rights reserved.
