Biosorption, preconsanration of Pb(II) using amberlite XAD-16 resin modified by Anoxybacillus sp.SO-B1 bacteria and its determination by AAS

In the present study, Pb(II) ions present in aqueous medium were enriched by a mini column containing modified Amberlite XAD-16 and determined by Flame Atomic Absorption Spectroscopy (FAAS). Influences of some factors, such as pH, type, concentration, and volume and flow rate of recovery solution, sorption capacity on enrichment yield were investigated.In the optimum conditions, recovery yield of Pb(II) ions was found to be 100,3±0,49% (N = 5). In order to investigate applicability of the method to the real samples, effects of several ions, such as Na+, K+, Mg2+, Cl- and NO3 on recovery yield were studied.The proposed method was applied to real samples, such as Tigris River water, for determination of Pb(II) ions and the recovery yield was found as 32,4±0,549 % (N = 5). Furthermore, accuracy of the method was checked by analyzing with the standard reference material.
