title: Sorption studies of diethylketone in the presence of Al3+, Cd2+, Ni2+and Mn2+, from lab-scale to pilot scale.
abstract: The toxic effects of diethylketone (DEK) in aqueous solution with different concentrations of Al3+, Cd2+, Ni2+and Mn2+were evaluated at lab-scale. It was established that Streptococcus equisimilis is able to efficiently remove DEK with different concentrations with heavy metals. It was proved that this joint-system has excellent capacity to biodegrade high concentrations of DEK in the presence of Al3+, Cd2+, Ni2+and Mn2+. With the exception of Al3+, the uptake for all metals increased as the initial concentration of each metal in the mixed solution increased. The breakthrough curves are best described by the Adams and Bohart model for Cd2+, by the Yoon and Nelson model for Ni2+and by the Wolborska model for Mn2+.
