“…The use of agriculture byproducts such as coconut fruit (Anirudhan and Sreekumari 2011), nuts apricot (Tsibranska and Hristova 2010), beet pulp (Pehlivan et al 2008), stems of tea (Amarasinghe and Williams 2007), rice husk (Bakircioglu et al 2003;Wong et al 2003), pentandra hulls (Madhava-Raoa et al 2006)and olive stones-waste (Alslaibi et al 2015;Baccar et al 2009;Gharib and Ouederni 2005), which are inexpensive, abundantly available, and renewable materials, as precursor for activated carbon production, reduces adsorption processing costs (Bailey et al 1999). The adsorption process offers flexibility in design and operation and in many cases will produce high-quality treated effluent (Fu and Wang 2011;Cui et al 2016).…”

The present work reports the synergistic and inhibitory adsorption effects involved in the multicomponent adsorption of heavy metal ions (Cu(II), Ni(II), and Cd(II)) from binary systems using chemically olive stone activated carbon (COSAC) as adsorbent. In order to evaluate the adsorption capacity of COSAC to remove studied heavy metals, adsorption of metal ions in single and binary systems were conducted. Kinetics adsorption rates in binary systems are very fast as compared to that in single ones and well represented by the pseudo second-order. Langmuir and Sips model fit mono-solute adsorption isotherms and the maximum adsorption capacity of COSAC decreased in the following order: Cd(II) [ Ni(II) [ Cu(II). In binary equilibrium systems, the effect of initial concentration of interfering metal ions on the removal of target ones was studied. Different mutual interactions between metal ions dealing with the decrease and the enhancement of inhibitory and synergetic effects were detected. Results showed that the effects on the adsorption of the metal ions in binary mixture strongly depend on the initial concentration of both metal ions in the solution. In most of the scenarios studied, the total amount of metal ions adsorbed was higher than the sum of the ones obtained in single solutions, suggesting synergetic interactions between the two metal ions. This study proves that COSAC is an effective adsorbent for the removal of heavy metals from multicomponent solutions.

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...
