The biosorption potential of bioflocculent MBF-07 as the biosorbent for the removal of Pb²⁺ from aqueous solution was investigated.The effects of pH, dose, contact time, and temperature on the biosorption processes were studied by batch. The results showed that the extent of adsorption capacity was 62.1 mg/g when the dosage of biosorbent was 20 mg, pH=5, adsorption contact time was 90 min, initial Pb²⁺ concentration of aqueous solution was 50 mg/l, respectively. And the maximum absorption capacity of activated carbon was 115.4 mg/g. Moreover, the adsorption reaction of Pb²⁺ by bioflocculent MBF-07 consistent with the both Langmuir and Freundlich isotherms models.
