Synthesis and performance of cross-linked poly(vinylpyridine-co-protoporphyrin) for effective cobalt determination using a micro-packed column hyphenated system coupled to FAAS

Utilization of a plasticized PVC optical sensor for the selective and efficient detection of cobalt(ii) in environmental samples

“…A variety of sensitive and selective analytical methodologies such as electroanalysis, 5 atomic absorption spectrometry (AAS), 6 flame atomic absorption spectrometry (FAAS), 2,7–12 electrothermal atomic absorption spectrometry (ET-AAS), 13,14 chemiluminescence, 15 X-ray fluorescence, 16 laser-induced thermal lens spectrometry, 17 neutron activation analysis (NAA), 18 inductively coupled plasma optical emission spectroscopy (ICP-OES), 19,20 inductively coupled plasma mass spectrometry (ICP-MS), 21 and spectrophotometry 22–30 have been demonstrated for the assessment of cobalt in various samples. However, many of these methods involve the risk of sample contamination and analyte loss due to the sample preparation and preconcentration steps.…”
