摘要：
Selected biofilms attached to granular activated carbon significantly enhance metal recovery through biosorption. To describe uptake of five metals, the Freundlich isotherm model was found superior to the Langmuir. Calculated diffusion coefficients through the biofilm indicated a dependence between diffusivity and metal ion concentration.
