“…Best adjustment of data (Table 2) was found for the Langmuir model [35] that states: (i) the sorption takes place at homogenous sites in the sorbent material; (ii) there is no interaction between the ions, and (iii) the metal is sorbed forming a monolayer coverage on the adsorbent surface.…”

The ability of calcium aluminate cement (CAC) to encapsulate toxic metals (Pb, Zn and Cu) was assessed under two curing conditions. Changes in the consistency and in the setting time were found upon the addition of the nitrates of the target metals. Both Pb and Cu caused a delay in CAC hydration, while Zn accelerated the stiffening of the mortar. Compressive strengths of the metal-doped mortars, when initially cured at 60ºC/100% RH, were comparable with that of the free-metal mortar. Three different pore size distribution patterns were identified and related to the compounds identified by XRD and SEM. Sorbent capacities of CAC for the toxic metals were excellent: a total uptake was achieved for up to 3 wt.% loading of the three metals. In this way, CAC mortars were perfectly able to encapsulate the toxic metals, allowing the use of CAC for waste management as proved by the leaching tests.

“…In the process of adsorption, the gas liquid solute gathers on the adsorbent surface which forms a molecular film of the adsorbent. For the removal of metal ions and other recalcitrant compound from the industrial effluents, activated charcoal, synthetic resins, agricultural waste and industrial waste used as adsorbent followed by physical, biological, and chemical methods (Yadanaparthi et al, 2009, Kwon et al, 2010and Gottipati et al, 2012. Activated carbon: Activated carbon is the commonly preferred adsorbent; its widespread use is restricted due to high cost.…”

In the present review, the suitability of adsorption process using low cost adsorbent for the treatment of pulp and paper mill effluent has been discussed. It is clear that adsorption processes are appropriate for the removal of recalcitrant compounds such as surfactants and pesticides, among others biodegradable or non-biodegradable compound present in pulp and paper mills effluents. The importance of the adsorption is to improvement of the removal of various physico-chemical (biological oxygen demand (BOD), chemical oxygen demand (COD), colour, suspended solids, lignin), heavy metals (Cu, Cr, Fe, Zn, Ni and Mn etc) organochlorine compounds, all recalcitrant pollutant, reduce toxicity, enhance colour removal by using different cost effective adsorbents. The effective use of the different adsorbents developed from different adsorbent media such as activated carbon, agriculture by product and industrial wastes and sludge as adsorbents for the removal of different pollutants from the various processes and operations of pulp and paper mill as potential alternatives to different treatment process and received widespread attention. Adsorption necessity is a novel treatment option to improve the efficiency of removal within the discharge limits of wastewaters into the receiving bodies without causing any damage of the environment. However, still there is a need to find out the practical usefulness of such low cost adsorbent at industrial scale with the special reference to metals.

Adsorción de metales pesados en aguas residuales usando materiales de origen biológicoAdsorption of heavy metals in waste water using biological materialsCandelaria Tejada-Tovar 1 , Ángel Villabona-Ortiz 2 y Luz Garcés-Jaraba 3Recibido: 10 de junio de 2014, Aceptado: 26 de octubre de 2014Cómo citar / How to cite C. Tejada-Tovar, A. Villabona-Ortiz y L. Garcés-Jaraba, "Adsorción de metales pesados en aguas residuales usando materiales de origen biológico", Tecno Lógicas, vol. 18, no. 34, pp. 109-123, 2015 ResumenLa bioadsorción es un proceso que permite la captación activa o pasiva de iones metálicos, debido a la propiedad que diversas biomasas vivas o muertas poseen para enlazar y acumular este tipo de contaminantes por diferentes mecanismos. La aplicación de materiales de bajo costo obtenidos a partir de diferentes biomasas provenientes de la flora microbiana, algas y residuos agroindustriales ha sido investigada para reemplazar el uso de métodos convencionales en la remoción de contaminantes, tales como los metales pesados. Entre los metales de mayor impacto al ambiente por su alta toxicidad y difícil eliminación se encuentran el cromo, níquel, cadmio, plomo y mercurio. En el presente trabajo se estudian las generalidades de la adsorción como proceso alternativo para la remoción de contaminantes en solución y las biomasas comúnmente usadas en estos procesos, además de algunas de las modificaciones realizadas para la mejora de la eficiencia de adsorción de las mismas. Se concluye que el uso de la adsorción en la remoción de contaminantes en solución acuosa mediante el uso de biomasa residual es aplicable a estos procesos de descontaminación evitando problemas subsecuentes como la generación de lodos químicos, y generando un uso alternativo a materiales considerados como desechos. Se identifica además que factores como el pH de la solución, tamaño de partícula, temperatura y la concentración del metal influyen en el proceso.

AbstractBiosorption is a process that allows active or passive uptake of metal ions due to the property that different living or dead biomass have to bind and accumulate these pollutants by different mechanisms. The application of low-cost materials obtained from different biomass from microbial flora, agro-industrial waste and algae has been investigated to replace the use of conventional methods for the removal of contaminants such as heavy metals. Some of the metals of greatest impact to the environment due to its high toxicity and difficult to remove are chromium, nickel, cadmium, lead, and mercury. In this paper, an overview of adsorption as an alternative process for the removal of contaminants in solution and biomass commonly used in these processes, as well as some of the modifications made to improve the efficiency of adsorption of these materials is presented. It was concluded that the use of adsorption in the removal of pollutants in aqueous solution using waste biomass is applicable to these decontaminatio...
