Biomassa, Águas residuais, Remediação, AdsorçãoResumo
A poluição dos recursos hídricos é alvo de preocupação mundial nos últimos tempos devido ao importante papel da água limpa e de qualidade sobre a sobrevivência dos organismos vivos. As águas residuais de processos industriais são conhecidas por produzirem vários poluentes, incluindo metais pesados. O objetivo desta pesquisa desenvolver um adsorvente derivado da modificação química da casca do amendoim para remediação da contaminação por cobre em amostras de água. Os ensaios foram realizados avaliando-se a adsorção do complexo fenantrolina-cobre pela biomassa via determinação espectrofotométrica de absorção molecular (Uv-Vis). De acordo com o planejamento fatorial aplicado (23), as melhores condições de adsorção alcançadas foram o tempo de contato de 8 horas, a concentração do metal de 0,1 mg L-1 e 2 g da biomassa adsorvente onde obteve-se uma eficiência de 18,50%. Da análise de variância (ANOVA) pôde-se inferir que a concentração de Cu2+ (p = 0,00001) e a interação tempo de contato x concentração de Cu2+ (X1X2) (p = 7,34x10-5) tiveram a maior significância no processo de adsorção. Portanto, a biomassa utilizada apresenta potencial na remediação do metal cobre em amostras de água.
