Abstract

Zhou, B.J. and Zhang, H., 2020. Pb (II) biosorption using biomass of green algae. In: Guido Aldana, P.A. and Kantamaneni, K.

Lead (Pb) pollution in water refers to the severe issue about the environment globally, and sorption using biomaterial is a viable method to remove lead in aqueous solutions. The work used the biomass of green algae (Chlorella pyrenoidosae) to investigate how temperature, contact time, biomass dose, pH, and initial Pb (II) concentration affect the biosorption of Pb (II) were investigated. At pH 5.5 and 30°C after 150 min, the largest retention efficiency of Pb (II) had been observed at 100 mg/L of Pb (II) in 100 mL solutions with 1.0 g biomass. Besides, the Langmuir isotherm equation was used to obtain the maximum biosorption of 74.6 mg/g. The equilibrium data matched the Langmuir isotherm model well. Kinetics studies revealed the pseudo-first-order model applicable in the bio-absorption processes of Pb (II) using the green algae biomass. Study indicated biomass of the green algae was an efficient biosorbent for Pb (II).
