Water contamination by heavy metals is caused by various anthropogenic activities that alter ecosystems and health. Thus, this research determined the efficiency of activated carbon from Prunus persica and Persea americana for the removal of arsenic and lead in contaminated water. The activated carbons were physically and chemically characterized. For the removal of metals, tests were carried out using different doses (3, 5 and 7 g) of activated carbon and different contact times (1, 15 and 30 min). The results indicated that, with respect to the characteristics of granulometry, porosity, humidity and organic matter, the activated carbon from Persea americana presented 0.85 mm, 0.51%, 74% and 92%, respectively. Whereas, the activated carbon from Prunus persica showed 0.85 mm, 0.48 %, 68% and 87%, respectively. In addition, activated from Prunus persica achieved arsenic and lead removals of 96.94% and 97.19%, respectively. Whereas, the activated carbon from Persea americana achieved removals of 95.37% and 95.52%, respectively. On the other hand, physico-chemical parameters such as electrical conductivity, turbidity, BOD5, COD, suspended solids and oils and greases also showed significant reductions. In conclusion, both activated carbons have great potential in the removal of arsenic and lead, and can be applied in the treatment of water contaminated with these metals.
