TI  - Efficiency and application of 
      poly(acryldinitrophenylamidrazone-dinitroacrylphenylhydrazine) chelating fiber 
      for pre-concentrating and separating trace Au(III), Ru(III), In(III), Bi(III), 
      Zr(IV), V(V), Ga(III) and Ti(IV) from solution samples.

AB  - Poly(acryldinitrophenylamidrazone-dinitroacrylphenylhydrazine) chelating fiber 
      was synthesized from polyacrylonitrile fiber and used for enrichment and 
      separation for traces of Au(III), Ru(III), In(III), Bi(III), Zr(IV), V(V), 
      Ga(III) and Ti(IV) ions from solution samples. The acidity, rate, re-use, 
      capacity and interference on the adsorption of ions on the chelating fiber as 
      well as the conditions of desorption of these ions from the chelating fiber were 
      investigated by means of inductively coupled plasma optical emission 
      spectrometry. The results show that 10-100 ngml(-1) of Au(III), Ru(III), In(III), 
      Bi(III), Zr(IV), V(V), Ga(III) and Ti(IV) ions can be quantitatively enriched by 
      the chelating fiber at a 2 mlmin(-1) of flow rate in the range pH 4-5, and 
      desorbed quantitatively with 20 ml of 5 M HCl for In(III), Bi(III), Zr(IV), V(V), 
      Ga(III), Ti(IV) and 20 ml of 4 M HCl+2% CS(NH(2))(2) solution for Au(III), 
      Ru(III) (with recovery>95%). 50- to 500- fold excesses of Fe(III), Al(III), 
      Mg(II), Mn(II), Ca(II), Cu(II), Ni(II) ions cause little interference in the 
      concentration and determination of analyzed ions. When the fiber was reused for 8 
      times, the recoveries of the above ions enriched by the fiber were still over 
      87%. The relative standard deviations (RSDs) for the enrichment and determination 
      of 10 ngml(-1) Au, Ru, In, Bi, Ga and 1 ngml(-1) Zr, V, Ti were lower than 3.0%. 
      The results obtained for these ions in real solution samples by this method were 
      basically in agreement with the given values with average errors of less than 
      6.3%. FT-IR spectra show that existence of NNCNHNH, OCNHNH and NO(2) functional 
      groups are verified in chelating fiber, and Au(III) or Ru(III) is mainly combined 
      with nitrogen (or oxygen) of the groups to form a chelate complex.
