Resumo: The present work evaluated the efficiency of the dry biomass of water hyacinth (Eichornia crassipes) in the removal of heavy metals cadmium (Cd), lead (Pb), chromium (Cr), cupper (Cu), zinc (Zn) and nickel (Ni) from solutions prepared with these metals. The delineation used was entirely randomized, with five treatments (solutions with different concentrations of heavy metals) and four repetitions. The dry biomass remained in the treatment solutions for a period of 48h. In the intervals of 1; 2; 3; 6; 12; 24; 36 and 48h after experiment installation, samples were collected of each treatment, determining the greater removal for each heavy metal by water hyacinth dry biomass. Nitro-perchloric digestion was conducted in the dry biomass, and metal levels were determined in the dry biomass and in the samples by atomic absorption spectrometry, flame modality. The metals Cd, Pb, Cr, Cu e Zn were removed by water hyacinth dry biomass in the different treatments, whereas for Ni removal did not occur. The water hyacinth Eichornia crassipes is an excellent material for removal, in small and larger scales, of water bodies contaminated with heavy metals

O delineamento utilizado foi inteiramente casualizado, com cinco tratamentos (soluções com diferentes concentrações dos metais pesados) e quatro repetições. A biomassa seca permaneceu nas soluções dos tratamentos por um período de 48h, e nos intervalos de 1; 2; 3; 6; 12; 24; 36 e 48h após a instalação do experimento, coletaram-se alíquotas de cada tratamento, determinando-se a maior remoção de cada metal pesado pela biomassa seca do aguapé. Foi realizada digestão nitroperclórica na biomassa seca e determinação dos teores dos metais na biomassa e nas alíquotas por espectrometria de absorção atômica, modalidade chama. Para os metais Cd, Pb, Cr, Cu e Zn ocorreu remoção significativa pela massa seca do aguapé nos diferentes tratamentos, enquanto para o Ni não foi encontrada diferença significativa. Dessa forma, conclui-se que a biomassa seca produzida, a partir do aguapé Eichornia crassipes, é um excelente material para a remoção, tanto em pequena como em grande escala, de corpos hídricos contaminados com metais pesados.Universidade Estadual De Maringá2009-04-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/316610.4025/actascitechnol.v31i1.3166Acta Scientiarum.
