title: Adsorption and deposition-assisted anodic stripping voltammetry for determination of antimony(III) in presence of hematoxylin on glassy carbon electrode.
abstract: A validated simple, reliable and sensitive adsorptive anodic stripping voltammetric procedure is suggested for the accurate determination of antimony(III) on a glassy carbon electrode (GCE) in the presence of hematoxylin (HT), used as a chemical receptor in antimony analysis for the first time. Under optimized conditions, the plot of stripping peak current versus Sb(III) concentration showed two dynamic linear ranges, 1.0×10-4- 0.01µm (R2=0.9986) and 0.01 - 1.0µm (R2=0.9973) with a detection limit of 9.5×10-11molL-1(11.57ngL-1). The RSD values of intra-day precision and inter-day precision (n =5) for 5.0×10-7molL-1Sb(III) were calculated as 1.63% and 2.27%, respectively, indicating that the proposed method has a good precision. Recoveries for Sb(III) in water samples were found to be between 97% and 102% for the 5.0×10-7molL-1Sb(III), proving the reliability and accuracy of the method proposed.
