Abstract
Water pollution can be found in the oceans, seas, rivers and lakes which can be taken as organic pollutants or better known as emerging pollutants. Emerging pollutants (EP´s) are chemical substances that persist in the environment, these molecules are in the food chain causing risks and adverse effects for human health and the environment. EP´s are not they are discharged as effluents indiscriminately, for this reason is important to improve water treatment by the application of advanced techniques as adsorption. Adsorbents like alumina are known for their large surface area, high mechanical properties and good resistivity to thermal degradation. Aluminum oxide or alumina (Al2O3) is a solid white ceramic material which has been considered an efficient adsorbent for EP´s removal as advanced water treatment.
Highlights
Water is a resource distributed throughout the world, it can be found in oceans, rivers and lakes, that is considered as surface water, or can be found in aquifers
Review of alumina in adsorption processes for emerging pollutants water usually come from two different sources, among them, salts, metalloids and metals are considered in this kind of compounds and they are highly soluble
Another dye that has been removed with alumina is Orange G, Banerjee and collaborators in 2017 Banerjee et al (2017) studied the synthesis and application of alumina nanoparticles synthetizing by the sol gel technique and it was found that the particle size was in the range of 30-35 nm this for the removal of the aforementioned dye from aqueous solutions
Summary
Water is a resource distributed throughout the world, it can be found in oceans, rivers and lakes, that is considered as surface water, or can be found in aquifers (groundwater). The availability of this resource is related to caring and water quality, that ensures that the water is enough for its intended use “Estadísticas del agua en México” (2014). Review of alumina in adsorption processes for emerging pollutants water usually come from two different sources, (natural and anthropogenic), among them, salts, metalloids and metals are considered in this kind of compounds and they are highly soluble. The most dangerous sources of water pollution even in small concentrations are pesticides, dyes and pharmaceutical products which are considered EPs Rivera-Utrilla et al (2013)
