Résumé en anglais

Four macrophytes commonly used to clean up Cu contaminated effluents, i.e. Arundo donax L., Cyperus eragrostis Lam., Iris pseudacorus L. and Phalaris arundinacea L., were assessed to produce Cu-rich plant biomass intended for ecofriendly catalyst preparation. 7-month-old plants were exposed to a Cu gradient (0.08, 2, 10, 20 and 40 mu M Cu) in batch conditions during 2 months. Copper exposure affected the root DW yield of C. eragrostis from 2 mu M Cu, whereas I. pseudacorus and A. donax developed well. Maximum Cu concentration in the biomass of C. eragrostis and P. arundinacea (i.e. 255 and 838 mg Cu kg(-1) DW respectively) did not reach the 1000 mg Cu kg(-1) DW threshold value needed to produce Cu-ecocatalysts. Copper concentrations in the roots of I. pseudacorus and A. donax exceeded this threshold value at 40 mu M and over 10 mu M Cu, i.e. 1099 and 1809 mg Cu kg(-1) DW, respectively, making them relevant candidates for producing Cu-ecocatalysts.< Réduire
