The present work was developed to study the metal removal performance of unicellular algae isolated from the Reconquista River and to evaluate the effect of the presence of more than one metal in the removal process. Thus, native unicellular algae were isolated from the highly contaminated Reconquista River. All of the isolates were classified, al genus level, based on their morphological appearance. Nine isolated were screened for their Zn(II) removal capacity. Chorella sp. RR5 and Desmodesmus sp. RR7 were selected based on their removal performance, and their potential in the remediation of multiple metals was analysed. Therefore, zinc (Zn (II)), copper (Cu(II)) and chromium (Cr(VI)) removal was evaluated in mono and multi-metallic solution.
