Abstract [en]

An eco-friendly gamma-AlOOH-carbonated bacterial cellulose (gamma-AlOOH-CBC) hybrids material was fabricated by simple pyrolysis and hydrothermal treatments. The obtained hybrids possess an intrinsic 3D nanofibrous structure decorated with chaff-like gamma-AlOOH particles. Owing to the good adsorption property and conductive, gamma-AlOOH-CBC hybrids were used to modified the glass carbon electrode (GCE) for simultaneous determination of Cd(II) and Pb(II) in aqueous samples by differential pulse anodic stripping voltammetry (DPASV) method. Various parameters affected Cd(II) and Pb(II) measurement were optimized. Under the optimal conditions, the limit of detection (S/N = 3) of the gamma-AlOOH-CBC modified electrode was evaluated to be 0.17 mu g.L-1 for Cd(II) and 0.10 mu g.L-1 for Pb(II) with the linear range of the calibration curves ranged 0.5-250 mu g.L-1 for Cd(II) and Pb(II). Furthermore, the developed electrode was also successfully utilized for monitoring trace Cd(II) and Pb(II) in drinking water samples with satisfactory results.
