Ultra-trace determination of Cr (VI) ions in real water samples after electromembrane extraction through novel nanostructured polyaniline reinforced hollow fibers followed by electrothermal atomic absorption spectrometry

In the current study, a combination of nanostructured polyaniline reinforced electromembrane extraction (EME) and electrothermal atomic absorption spectrometry (ETAAS) was utilized for the extraction and preconcentration of ultra-trace amounts of Cr(VI) in real water samples.88
