Resumo: | Environmental Laws and Regulations to dump wastewater are increasingly relevant and, together with pressure from environmentalists, provide awareness of academics in search of solutions. In Brazil, federal law, through Resolution No. 357 of 17/03/05 of the National Environmental Council - CONAMA, in Article 24 deals with the disposal of these effluents. Water pollution with heavy metals is concern because of the difficulty of the treatment and removal from the environment. Copper, for example, is a metallic element and in the form of salt is very soluble in water which dificults its removal. In this context, this study aims to evaluate the extraction of copper with acrylamide polymers through the process of assisted flocculation followed by filtration. Therefore, we used acrylamide polymers, produced by SNF Floerger, with varying degrees of ionicity which is the parameter examined on the extraction of copper. We used the FA polymers FA 920 SH, AH 912 SH, AN 905 SH, AN 910 SH, AN 923 SH, AN 945 SH, AN 956 SH and AN 977 SH, which have anionicities different from each other and growing in that order. The parameters temperature, pH, concentration of the copper solution and stirring speed are fixed. The polymer solution was added to a solution of 200 ppm copper, varying the concentration of polymer. After stirring, an assisted flocculation occurred followed by filtration of the effluent. The filtrate was analyzed by atomic absorption spectrophotometer and the percentage removal of copper ranged from 63 % to 97 %, noting that polymers with higher ionic charge were responsible for the highest percentage of copper extraction. The results of this study showed that these polymers can be applied in the treatment of wastewaters containing metals such as copper |

No Brasil, a legislação federal, através da Resolução nº 357, de 17/03/05 do Conselho Nacional do Meio Ambiente CONAMA, no Artigo 24, trata do descarte destes efluentes. A contaminação da água com metais pesados é uma preocupação em virtude da dificuldade de tratamento e remoção do ambiente. O cobre, por exemplo, é um elemento metálico e sob a forma de sal é bastante solúvel em água o que termina por dificultar sua remoção. Nesse contexto, o presente trabalho tem como objetivo avaliar a extração do cobre com polímeros a base de acrilamida através do processo de floculação seguido de filtração. Para tanto foram utilizados polímeros a base de acrilamida, fornecidos pela SNF Floerger, com vários graus de ionicidade, que é o parâmetro analisado sobre a extração do cobre. Foram utilizados os polímeros FA 920 SH, AH 912 SH, AN 905 SH, AN 910 SH, AN 923 SH, AN 945 SH, AN 956 SH e AN 977 SH, que apresentam anionicidades diferentes entre si e crescente nessa ordem. Os parâmetros temperatura, pH, concentração da solução de cobre e velocidade de agitação foram fixados. A solução do polímero foi adicionada à solução do cobre a 200 ppm, variando a concentração de polímero. Após a agitação, ocorreu uma floculação assistida e em seguida filtração do efluente. O filtrado foi analisado no espectrofotômetro de absorção atômica e o percentual de remoção de cobre variou entre 63% a 97%, observando-se que os polímeros com maior carga iônica foram os responsáveis pelo maior percentual de extração de cobre. Os resultados obtidos neste trabalho mostraram que é possível aplicar esses polímeros no tratamento de efluentes contendo metais como o cobre ou similaresapplication/pdfporUniversidade Federal do Rio Grande do NortePrograma de Pós-Graduação em Engenharia QuímicaUFRNBRPesquisa e Desenvolvimento de Tecnologias RegionaisMetais Pesados.
