Utilização de solos locais para tratamento de efluentes do refino de petróleo contendo metais

Year: 2007

Type: article

Abstract: The employment of local soils for extraction of metallic elements was evaluated through batch tests to treat wastewaters generated in a petroleum refinery plant in southern Brazil.Clay and organic carbon content and clay mineralogy provide these soils, in principle, with moderate metal retention capacity.The following retention order was established: Cr 3+ > Pb 2+ > Cu 2+ > Hg 2+ > Cd 2+ , with total amount of metals retained varying from 36 to 65 meq kg -1 .The results show the high efficiency of local soils for extracting metals from liquid effluents through sorption and precipitation processes under acid pH conditions.
