Under optimized conditions, the plot of stripping peak current versus Sb(III) concentration showed two dynamic linear ranges, 1.0x10(-4) - 0.01 mu m (R-2 =0.9986) and 0.01 - 1.0 mu m (R-2 =0.9973) with a detection limit of 9.5x10(-11) mol (11.57 ng L-1). The RSD values of intra-day precision and inter-day precision (n =5) for 5.0x10(-7) mol L-1 Sb(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 5.0x10(-7) mol L-1 Sb(III), proving the reliability and accuracy of the method proposed.eninfo:eu-repo/semantics/closedAccessHematoxylinAntimony(IlI) determinationAdsorptive anodic stripping voltamtnetryGlassy carbon electrodeArticle16467768310.1016/j.talanta.2016.10.103Q1WOS:0003932444000942-s2.0-8500631456528107989Q1
