2008 SEP 29 - (VerticalNews.com) -- According to recent research from Xinxiang, People's Republic of China, "This paper describes a new method using TiO2 nanotubes, a new material, as solid-phase extraction adsorbent for the sensitive determination of trace copper prior to flame atomic absorption spectrometry (FAAS) analysis. Important parameters, which would affect the enrichment performance such as sample pH, the eluent and its volume, sample flow rate, sample volume, and concomitant ions have been optimized, respectively The experimental results exhibited that copper could be adsorbed quantitatively on TiO2 nanotubes at a pH of 7.0, and easily eluted with ethanol. ...read more

  2008 SEP 29 - (VerticalNews.com) -- "The possibility of using modified carbon nanofibers (CNFs) as solid phase extractants for the speciation of Cr(III) and Cr(VI) has been investigated by a microcolumn coupled with inductively coupled plasma mass spectrometry (ICP-MS). Experiments were performed to optimize conditions, such as pH, sample flow rate, sample volume and concentration of eluent, to achieve the quantitative separation of Cr(III) and Cr(VI)," investigators in Wuhan, People's Republic of China report ...read more
