摘要: Abstract A study was made of the capabilities iminodiacetic acid/ethylcellulose (IDAEC) to serve as chelating resin for preconcentrating trace elements together with a computer-assisted on-line flow injection analysis-inductively coupled plasma atomic emission spectrometry technique. The system tested few analytes particular clinical and environmental importance (Cd, Co, Cu Pb) in matrices such water, sea water urine. performance IDAEC compared that carboxymethylated polyethyleneimine-polymethylenepolyphenylene isocyanate (CPPI) Chelex 100 regard enrichment factor, analytical throughput recovery. With several obvious advantages over batch procedure, mode improved detection power by one two orders magnitude allowed twelve samples per hour be treated. appears most convenient terms efficiency long-term performance.
