A polyacrylacylisothiourea chelating fibre was synthesized using polya
crylonitrile fibre as a starting material, and the structure of the ch
elating fibre was determined by infrared spectrometry. The parameters
influencing the efficiency of the fibre at concentrating trace amounts
of Au-III, Pd-IV, and Rum, including acidity, Bow rate, adsorption ca
pacity, effect of re-use, interfering ions, and desorption, were inves
tigated. Gold(I1I), Pd-IV, and Ru-III were enriched and separated from
real samples and were detected using inductively coupled plasma optic
al emission spectrometry with satisfactory results. For concentrations
of Au-III, Pd-IV, and Ru-III of 0.008 mg l(-1), the relative standard
deviation was 1.8% for Au-III, 2.5% for Pd-IV, and 0.8% for Ru-III. T
he concentrations obtained for these ions in real solution samples by
this method were basically in agreement with the given values, with av
erage errors of less than 2.5%. The method is rapid, precise, simple,
and convenient to use.
