Description

A new poly(acryl-p-nitrophenylamidrazone-p-nitrophenylhydrazide) chelating fibre was synthesized from polyacrylnitrile fibre, and the structure of the chelating fibre was determined with the help of the FT-IR spectrum. The parameters influencing the efficiency of the fibre for concentrating trace amounts of Bi3+, In3+, Sn4+, Ga3+ and Ti4+, including sample acidity during enrichment, flow rate, adsorptive capacity, re-usability, interfering ions and desorption conditions were investigated. Trace Bi3+, In3+, Sn4+, Ga3+ and Ti4+ were enriched and separated from real sample solutions and detected using inductively coupled plasma optical emission spectrometry (ICP-OES) with satisfactory results. The experiments show that the method is rapid, precise, simple and convenient to use
