For the first time, biosorption of lead(II) using a PAHs-degrading bacterium, Herbaspirillum chlorophenolicum FA1, was investigated as a function of initial lead concentration, biomass dosage, pH, and temperature in batch conditions. Results showed that FA1 was highly resistant to lead and grew well even at lead concentration of 200 mg L−1. The kinetic and isotherm data were well described by commonly used models, such as the pseudo-second-order and Langmuir models. Adsorption thermodynamics was spontaneous and endothermic, and FA1 exhibited a high sorption capacity of 151.52 mg g−1. SEM-EDS and FTIR analysis was conducted to further explore the interaction mechanisms.
