摘要: Abstract Titanium dioxide nanotubes (TDNTs) were used as a solid phase extraction adsorbent for chromium species by packed microcolumn coupled with inductively plasma mass spectrometry (ICP-MS), including total, suspended and soluble well Cr(III) Cr(VI) in tea leaves infusion. The experimental results indicated that was quantitatively retained on TDNTs the pH range of 5.0–8.0, while remained solution. total determined after reducing to Cr(III). concentration is calculated difference between Under optimal conditions, detection limits this method 0.0075 ng mL−1 relative standard deviation 3.8% (n = 9, c = 1.0 ng mL−1). This applied analysis speciation its distribution content leaves, infusion certified reference material satisfactory results.
