Abstract：Freeze-drying-inactivated Oscillatoria lutea Immobilized (FI) and Hot-air-inactivated Oscillatoria lutea Immobilized (HI) were used as adsorbents for Pb2+ adsorption from the solution with Freeze-drying-inactivated Oscillatoria lutea Free (FF) and Hot-air-inactivated Oscillatoria lutea Free (HF) as control samples. The effects of pH, contact time, Pb2+ initial concentrations and co-existing ions on adsorption capacity and the adsorption mechanism were investigated. Results showed that FI presented the best adsorption performance, which was better than HI and control samples. The pH, contact time, initial Pb2+ concentrations and coexisting ions influenced adsorption capacity of Pb2+ with the consistent trends with FI, HI and control samples. The adsorption capacities with FI and HI depended on pH, reaching the highest value at pH=5; With the initial Pb2+ concentrations increased, the adsorption capacity increased, and the equilibrium adsorption capacities were 80and 60mg/L, respectively; the adsorption capacities got equilibrium after 90 and 60 min contact time, respectively; and the coexisting ions were found to inhibited the adsorption of Pb2+ and the order of inhibition was: Ca2+>Mg2+>K+>Na+. The adsorption of Pb2+ by the four adsorbents followed the pseudo-second- order kinetic equation, and the adsorption process was mainly affected by the chemical adsorption rate. The experimental results revealed that the adsorption isotherm process of FF and FI was in accordance with Langmuir and Freundlich model, the Pb2+ adsorption process by HI followed the Langmuir model, and HF fitted the Freundlich model. The Fourier transform infrared spectroscopy measurement suggested that the main functional groups in the Pb2+ adsorption process with FI were amino- and carboxyl- groups. Further, the mechanisms of adsorption process involve the ion exchange, electrostatic attraction, and complexation. The cyclic adsorption results established the high potential of FI as a robust and promising adsorbent for industrial treatment of Pb2+.
