Utilização de solos locais para tratamento de efluentes do refino de petróleo contendo metais Employment of local soils for treatment of metal-bearing wastewater from petroleum refinement
<abstract language="eng">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 pr...
