TI  - Zwitterion-functionalized polymer microspheres as a sorbent for solid phase 
      extraction of trace levels of V(V), Cr(III), As(III), Sn(IV), Sb(III) and Hg(II)

AB  - This paper describes the preparation of zwitterion-functionalized polymer 
      microspheres (ZPMs) and their application to simultaneous enrichment of V(V), 
      Cr(III), As(III), Sn(IV), Sb(III) and Hg(II) from environmental water samples. 
      The ZPMs were prepared by emulsion copolymerization of ethyl methacrylate, 
      2-diethylaminoethyl methacrylate and triethylene glycol dimethyl acrylate 
      followed by modification with 1,3-propanesultone. The components were analyzed by 
      elemental analyses as well as Fourier transform infrared spectroscopy, and the 
      structures were characterized by scanning electron microscopy and transmission 
      electron microscopy. The ZPMs were packed into a mini-column for on-line 
      solid-phase extraction (SPE) of the above metal ions. Following extraction with 
      40 mM NH(4)NO(3) and 0.5 M HNO(3) solution, the ions were quantified by ICP-MS. 
      Under the optimized conditions, the enrichment factors (from a 40 mL sample) are 
      up to 60 for the ions V(V), As(III), Sb(III) and Hg(II), and 55 for Cr(III) and 
      Sn(IV). The detection limits are 1.2, 3.4, 1.0, 3.7, 2.1 and 1.6 ng L(-1) for 
      V(V), Cr(III), As(III), Sn(IV), Sb(III) and Hg(II), respectively, and the 
      relative standard deviations (RSDs) are below 5.2%. The feasibility and accuracy 
      of the method were validated by successfully analyzing six certified reference 
      materials as well as lake, well and river waters. Graphical abstract 
      Zwitterion-functionalized polymer microspheres (ZPMs) were prepared and packed 
      into a mini-column for on-line solid-phase extraction (SPE) via pump 1. Then 
      V(V), Cr(III), As(III), Sn(IV), Sb(III) and Hg(II) ions in environmental waters 
      were eluted and submitted to ICP-MS via pump 2.
