Application of Shewanella xiamenensis Placed on Zeolite in Treatment of Silver-Containing Effluents

The adsorption properties of Shewanella xiamenensis immobilized on zeolite have been evaluated in order to determine its applicability for remediation silver-containing effluents with different chemical composition. effects pH (2.0–6.0), contact time (15–150 min), silver concentration (10–100 mg/L) and temperature (20–50 °C) the bio-zeolite efficiency were investigated batch experiments. optimal metal ions removal was range 4.0–6.0, while required attained equilibrium lay between 60 150 min. described by a pseudo-second-order kinetic model Ag- Ag-Cu-Ni-Zn systems, Ag-Cu it fitted well pseudo-first-order model. maximum capacities calculated from Langmuir 14.8 mg/g (Ag system), 32.5 (Ag-Cu system) 12.8 (Ag-Cu-Ni-Zn system). thermodynamic parameters showed that onto spontaneous entropy-driven process.
