AB  - Speciation analysis of inorganic arsenic, chromium and selenium in environmental 
      waters is of great significance for the monitoring of environmental pollution. In 
      this work, 3-(2-aminoethylamino) propyltrimethoxysilane (AAPTS) functionalized 
      multi-wall carbon nanotubes (MWCNTs) were synthesized and employed as the 
      adsorbent for simultaneous speciation analysis of inorganic arsenic, chromium and 
      selenium in environmental waters by microcolumn solid-phase extraction 
      (SPE)-inductively coupled plasma mass spectrometry (ICP-MS). It was found that 
      As(V), Cr(VI) and Se(VI) could be selectively adsorbed on the microcolumn packed 
      with AAPTS-MWCNTs adsorbent at pH around 2.2, while As(III), Cr(III) and Se(IV) 
      could not be retained at this pH and passed through the microcolumn directly. 
      Total inorganic arsenic, chromium and selenium was determined after the oxidation 
      of As(III), Cr(III) and Se(IV) to As(V), Cr(VI) and Se(VI) with 10.0 mumol L(-1) 
      KMnO4. The assay of As(III), Cr(III) and Se(IV) was based on subtracting As(V), 
      Cr(VI) and Se(VI) from the total As, Cr and Se, respectively. Under the optimized 
      conditions, the detection limits of 15, 38 and 16 ng L(-1) with the relative 
      standard deviations (RSDs) of 7.4, 2.4 and 6.2% (c=1 microg L(-1), n=7) were obtained 
      for As(V), Cr(VI) and Se(VI), respectively. The developed method was validated by 
      analyzing four Certified Reference Materials, rainwater, Yangtze River and East 
      Lake waters.
