AB  - The bottleneck of applying stir bar sorptive extraction (SBSE) to elemental 
      speciation analysis is lack of suitable extraction phases with good affinities to 
      different elemental species. In this paper, a newly high polar extraction phase 
      of titania immobilized polypropylene hollow fiber (TiO(2)-PPHF) was prepared by 
      sol-gel immersion and low temperature hydrothermal process and the obtained 
      TiO(2)-PPHF inherits the adsorption properties of TiO(2) and the toughness of PPHF. 
      With a suitable size of stainless steel magnetic bar inserted into the prepared 
      TiO(2)-PPHF, a disposable TiO(2)-PPHF coating stir bar was obtained. The prepared 
      TiO(2)-PPHF was characterized by X-ray diffraction spectrometry and scanning 
      electron microscopy and the significant parameters affecting the extraction 
      efficiency of different arsenic species were studied. Based on the above facts, a 
      new method of SBSE combined with high performance liquid chromatography 
      (HPLC)-inductively coupled plasma mass spectrometry (ICP-MS) was developed for 
      the speciation of phenyl arsenic compounds and their possible transformation 
      products in chicken tissues. Under the optimal conditions, limits of detection 
      (LODs) of the developed method for eight target arsenic species were in the range 
      of 11.4-64.6 ng L(-)(1) with enrichment factors of 8.5-22.3 (theory enrichment factor 
      was 50), and the relative standard deviations (RSDs) were varying from 6.3 to 
      12.6% (c(AsIII/V)=5 mug L(-)(1), c(MMA,DMA,p-ASA,4-OH,3-NHPAA,PA,4-NPAA)=10 mug L(-)(1), 
      n=7). The proposed method was successfully applied to the speciation of arsenic 
      in chicken meat/liver samples and the recoveries for the spiked samples were in 
      the range of 78.5-120.4%. In order to validate the accuracy of the proposed 
      method, a certified reference material of BCR-627 tuna fish tissue was analyzed 
      and the determined values were in good agreement with the certified values. The 
      TiO(2)-PPHF was demonstrated to be a highly selective coating for the target 
      arsenic species, and could be easily prepared in batches with low cost. In 
      addition, with the disposable coating, the carry-over effect commonly encountered 
      in conventional SBSE was avoided.
