“…At a higher initial concentration, the available sites of adsorption become fewer and hence the percentage adsorption depends on the initial concentration. For a fixed adsorbent dose, the total available adsorption sites are limited, thereby adsorbing almost the same amount of the adsorbate, thus resulting in a decrease in percentage adsorption corresponding to an increase in initial adsorbate concentration (Calisir et al, 2009).…”

This study on the removal of cobalt ions from aqueous solutions by red mud was conducted in batch condition. Its objective was to investigate the possibility of using red mud waste material as an alternative to high cost commercial adsorbent materials for the removal of cobalt from aqueous solution. In this study, batch experiments were carried out for the adsorption of cobalt onto red mud industry waste. The red mud waste material was successfully used for the removal of cobalt ion from aqueous solution and the technique appears industrially applicable and viable. The potential of economically cheap waste materials like red mud was assessed for cobalt adsorption from aqueous solutions. The operating variables studied were contact time, initial solution pH, initial metal concentration, temperature and adsorbent dosage. The experimental investigation results show that activated red mud has a high level of adsorption capacity for cobalt ion. The adsorption data was correlated with the Langmuir and Freundlich isotherm models. It was found out that the Langmuir and Freundlich isotherms fitted well to the data. Consequently, it was concluded that the red mud can be successfully used for the removal of the cobalt ions from the aqueous solutions with heavy metals.

“…Discarded tires are an inexpensive medium for the adsorption of toxic compounds. Annually 250,000,000 used tires are accumulated in the 15 member states of the European Union and less of 35% were land filled (Calisir et al 2009). Moreover, tires could contribute largely to high levels of microplastics in the environment by abrasion also (Sommer et al 2018).…”

Polymeric materials have had an exponential growth since the Second World War, so that in 2018 the annual world production was 359 million tons. This has generated a contamination problem because of its prolonged exposure to various chemical and environmental factors which have caused the formation of particles with a size less than 5 mm with a vast surface area and chemically stable and adjustable surface. For these reasons, these particles called microplastics (MPs) have been used as vectors for chemicals in the environment and, recently, in the removal of several pollutants from water. In this chapter, some representative examples of the use of microplastics for sorption of contaminants from water (pharmaceuticals, metal ions, and other organic compounds) are shown. The chapter is organized into two parts: the first part addresses MPs of commercial origin (virgin) and those reused after being

La generación de residuos de caucho se ha convertido en una preocupación global por su impacto negativo en el medio ambiente y en la salud humana. La legislación ambiental sobre la disposición de este tipo de residuos ha venido aumentando las exigencias a los fabricantes, comercializadores y usuarios, con lo cual se ha acelerado la búsqueda de alternativas para el reaprovechamiento de los residuos de caucho. Este artículo presenta una revisión bibliográfica acerca de las principales tendencias en la utilización del caucho reciclado, incluyendo aplicaciones actualmente comercializadas y otras derivadas, tanto de estudios terminados, como de líneas de investigación en desarrollo. Las aplicaciones con mayor potencial de volumen consumido son del sector infraestructura y construcciones civiles, especialmente asfaltos, concretos y materiales aislantes para construcción liviana. Algunas aplicaciones con potencial en el futuro cercano son los filtros para la limpieza de aguas contaminadas y como componente en materiales compuestos con matriz termoplástica o en poliuretano. Por último, se evidencia la pertinencia de continuar investigando sobre esta temática que posee unos retos científicos de alta relevancia, los cuales ameritan la mayor atención por el problema ambiental significativo asociado al manejo de los residuos de caucho.
