Abstract


In this study, the use of Adansonia digitata L. seed cake residue as a biosorbent for the removal of Pb2+ from aqueous solution was evaluated. Dried fruits of Adansonia digitata L. were collected from the Department of Biological Sciences, Ahmadu Bello University, Zaria. The seeds were mechanically removed, washed with sterile distilled water, sun dried, powdered, defatted using n-hexane and stored in the refrigerator for further studies. Standard stock solution (30 mg/l) of Lead Nitrate Pb(NO3)2 was prepared by weighing 30mg of the salt and dissolving in 1L of deionized water this was further diluted for further study and serve as model polluted water. Batch experiments were carried out to study the effect of pH, initial concentration of metal salts, dosage of biosorbent, and contact time. The experimental design was Cross Randomized Design (CRD) and one way Analysis of Variance (ANOVA) was used to determine significant difference among means of the various parameters measured. Duncan Multiple Range Test (DMRT) was used in separating means where significant. The level of significance was taken at p < 0.05. The result revealed that the removal efficiency of Pb2+ from aqueous solution increased as pH increased from 2 – 10, initial concentration of metal salt increased from 0 - 30 mg/L, dosage of biosorbent increased from 0 - 200mg/l, and as contact time increased from 0 - 60 min. From this study Adansonia digitata L. seed could be considered as a potential, eco-friendly, low cost, biosorbent for the removal of Pb2+ from aqueous solution.

Key words: Adansonia digitata L., Bioremediation, Biosorbent, Lead, Seed, Water
