Resumen:
Drinking water is the one that presents the most suitable form for the population
to consume, does not contain impurities, meets the established drinking standard and
does not pose a health risk. It is necessary to treat water, either through physical or
chemical processes. Adsorption is an efficient and accessible technique in the metal
removal sector in water treatment. It is a physical-chemical process involved in water
treatment in order to reduce metals, contaminants, industrial effluents and several other
pollutants. The adsorption capacity is related to the properties of the adsorbents and
affinity with the element to be removed from the water, making it essential to choose
the correct adsorbent to be used. Groundwater is a type of water that contributes to the
maintenance of life, resulting from the infiltration of part or all of the precipitated
rainwater, being of great importance for freshwater reservoirs. Thus, the objective of
this research is to analyze the efficiency of adsorbents for the treatment of groundwater
in relation to the cost-benefit and to verify the main adsorbents used in adsorption
through a literature review.
