Abstract

In the present investigation, the objective was to verify the efficiency of activated carbon from rice husk as an adsorbent medium for the removal of heavy metals from industrial effluents, such as lead, cadmium, arsenic, copper, iron, zinc, and chromium, since that these have negative impacts on the population. The research had a non-experimental cross-sectional approach, where a documentary review was carried out, reaching the selection of 5 investigations for the object of study, which comprise 4 theses and a research article referring to the physical and chemical properties of the rice husk; preparing data record sheets, where the necessary information from said investigations was gathered, where these were analyzed through tables and graphs; in the results they show that there are percentages of removal variation in the different heavy metals, such is the case of Junín that used this method with different doses of activated carbon from the rice husk, where the greatest removal capacity was in lead in 96.04% and for cadmium 95.89%, likewise in other studies for different metals, concluding that this method is efficient and sustainable to face various environmental problems of heavy metals present in water.
