Bioadsorption of heavy metals consists in a passive, fast and reversible catchment of the metal ions present in an aqueous solution by physic and chemical interactions on aviableornon-aviablebiological materials. In the present paper, a mixed culture of microorganisms from an activated sludge processwas used to reduce fourdifferent heavy metals contents from a synthetic solution. Copper, nickel, zinc and lead were prepared at a range of 5 - 30 mg/L. The bioadsorption intensity was determined at two values of mean cell retention time (sludge age).The results demonstrated that Freundlich’sisotherm adjusted well(R2> 0.95), with a relatively strong bioadsorption due to intensity parameter “n”.Copper, nickel, zinc and lead final contents were 74,60-77,68 %; 75,40-40,26 %; 74,54-78,38 % and 25,0-31,6 %for 5 and 10 days of sludge age respectively with non-significant differences. 2018 artículo científico 0041-8420 https://www.redalyc.org/articulo.oa?id=445558835014 https://www.redalyc.org/journal/4455/445558835014/ https://www.redalyc.org/journal/4455/445558835014/html/ https://www.redalyc.org/journal/4455/445558835014/445558835014.epub https://www.redalyc.org/journal/4455/445558835014/movil en http://www.redalyc.org/revista.oa?id=4455 Tecnología Química application/pdf Universidad de Oriente Tecnología Química (Cuba) Num.3 Vol.38 |
