Application of polyurethane foam loaded with BTAC in an on-line preconcentration system: cadmium determination by FAAS
(Spectrochimica Acta Part B: Atomic Spectroscopy, 2000)
Knotted reactors and their role in flow-injection on-line preconcentration systems coupled to atomic spectrometry-based detectors
(Taylor & Francis, 2005-12)
The progress in flow-injection (FI) on-line separation and preconcentration employing knotted reactors (KRs) as a sorption medium for organometallic complexes associated to atomic spectrometry techniques is reviewed in ...
On-line complexation/cloud point preconcentration for the sensitive determination of dysprosium in urine by flow injection inductively coupled plasma-optical emission spectrometry
(Springer Heidelberg, 2003-01)
An on-line dysprosium preconcentration and determination system based on the hyphenation of cloud point extraction (CPE) to flow injection analysis (FIA) associated with ICP-OES was studied. For the preconcentration of ...
Application of polyurethane foam loaded with BTAC in an on-line preconcentration system: cadmium determination by FAAS
(Spectrochimica Acta Part B: Atomic Spectroscopy, 2000)
In the present paper, the use of polyurethane foam modified by 2-(2-benzothiazolylazo)-2-p-cresol (BTAC) as a sorbent in an on-line preconcentration system to determine cadmium trace levels by FAAS is proposed. The procedure ...
