TRATAMENTO DE EFLUENTE SINTÉTICO DE CORANTE AZUL DE METILENO POR ELETROFLOCULAÇÃO
Abstract
No presente estudo a técnica de eletrofloculação foi aplicada à remoção do corante azul de metileno em solução sintética. Colorimetria foi utilizada para avaliar o grau de remoção de corante do efluente. Testes foram feitos para sete combinações de temperatura da água e pH. A análise dos dados experimentais demonstrou que a quantidade de corante removido depende do pH, da temperatura e da interação entre estas duas variáveis.Downloads
