AB  - Amine functionalized polyacrylonitrile fibers (PANFs) were prepared and applied 
      for the simultaneous separation and preconcentration of V(v), As(iii), Sn(iv), 
      Sb(iii) and Bi(ii) from environmental water samples in this paper. The functional 
      PANFs were first prepared by nucleophilic substitution reaction between 
      hydroxylamine hydrochloride and polyacrylonitrile fibers, and then the reactant 
      obtained in the first step was subjected to a ring opening reaction with 
      epichlorohydrin, followed by modification with triethylenetetramine (TETA). The 
      structure of the final polymer fibers was analyzed by Fourier transform infrared 
      spectroscopy (FT-IR), and the morphology was characterized by scanning electron 
      microscopy (SEM). A home-made solid phase extraction (SPE) pretreatment column 
      was filled with PANFs, and then online connected with inductively coupled plasma 
      mass spectrometry (ICP-MS) for quantitative determination of metal ions. Under 
      the optimized experimental conditions, the target metal ions were eluted rapidly 
      and quantitatively using 0.3 mol L-1 HNO3 solution. Only with 30 mL sample 
      solution, high enrichment factors of 120 were obtained for V(v), As(iii), Sn(iv) 
      and Sb(iii), and 115 for Bi(ii), respectively. The detection limits achieved were 
      low: 1.2, 0.9, 1.7, 1.5 and 2.3 ng L-1 for V(v), As(iii), Sn(iv), Sb(iii) and 
      Bi(ii), respectively, and the relative standard deviations (RSDs) were below 
      3.0%. The advanced fiber materials prepared in this work have the advantages of 
      low cost, environmental friendliness and high adsorption efficiency, and the 
      on-line preconcentration method has greatly improved the analysis efficiency. 
      Finally, the feasibility and accuracy of the method were validated by 
      successfully analyzing Certified Reference Materials (CRMs) as well as lake, 
      river and sea water samples.
