| Sumario: | Agricultural and industrial activities generate a large-scale contamination in the environment with heavy metals and certain organic compounds, affecting the fertility of soils and compromising aquifers and surface waters that could be potential sources of water for human consumption. Heavy metals such as arsenic, cadmium, lead are highly toxic and cause serious damage to various organs and systems of the body, but mainly affect the central and peripheral nervous system. On the other hand, some organic compounds such as dyes used in the textile industry (e.g., methylene blue, violet crystal, malachite green) cause severe effects on human health due to their mutagenic, teratogenic and carcinogenic properties. For this reason, it is important to emphasize the development of environmentally friendly remediation processes that allow the decontamination of the effluents generated as a result of agricultural and industrial activity.In recent years, the use of biosorbents has played a leading role in the development of methods for the removal of pollutants in the framework of "Green Chemistry", since they are not subject to any type of bioprocessing (e.g. obtaining an enzyme), are biodegradable and have the possibility of being reused. These systems offer a high surface-to-volume ratio and have many active binding sites on their surface through which contaminants can be efficiently retained under suitable conditions.This research project will be fundamentally focused on the use of new alternative biomaterials for the biosorption of pollutants, taking advantage of the great diversity of biological substrates that exist in our region, and therefore the different extractive properties that can be obtained based on the choice of a biosorbent. The biomaterials will be used for the removal of elemental and organic pollutants from agricultural and industrial effluents. In this way, the project aims to develop efficient and useful tools in the area of environmental remediation, which allow offering economic and environmentally friendly processes for the decontamination of effluents. |
