AB  - A new specific phosphine modified polymer microsphere (PPMs) was designed and 
      used as the core adsorbent to comprehensively enrich both inorganic and organic 
      arsenic species in environmental waters by on line solid-phase extraction (SPE). 
      Avoiding any redox reagent, all the four arsenic species have been quantitatively 
      retained on the home made mini-column with large number of positively charged 
      adsorption groups, and then eluted rapidly (within seconds) with a mixed solution 
      of ammonium nitrate and ammonium dihydrogen phosphate. The trace separation and 
      determination of As(III), DMA, MMA and As(V) species have been simultaneously 
      achieved by high performance liquid chromatography hyphenated to inductively 
      coupled plasma spectrometry (HPLC-ICP-MS) technique. This work has developed a 
      versatile tri-n-butylphosphine functionalized polymer microsphere for an 
      efficient and reliable on-line of simultaneous preconcentration and detection of 
      inorganic and organic arsenic speciation. Under the optimized experimental 
      conditions, the enrichment factors obtained for As(III) and DMA with 25mL sample 
      solution were 28, while for MMA and As(V) reached 30. The low detection limits of 
      1.2ngL(-1), 0.96ngL(-1), 0.82ngL(-1) and 0.91ngL(-1), with the relative standard 
      deviations (RSDs) of 3.9%, 5.6%, 3.2% and 4.5% were obtained for As(III), DMA, 
      MMA and As(V), respectively. The developed method was validated by analyzing 
      Certified Reference Materials GSBZ 07-3171-2014, promising for routine monitoring 
      of arsenic species in lake water, river water and seawater samples.
