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 ...
An application of pressure/temperature-controlled microwave heating curves for the mineralization of tuna material prior to spectrometric quantification of mercury

A ruthenium-rhodamine complex as an activatable fluorescent probe
(American Chemical Society, 2010-07)
We describe the synthesis and characterization of a ruthenium-bipyridyl complex bearing a rhodamine-based fluorescent ligand. The complex is weakly fluorescent due to the quenching of rhodamine. Upon irradiation of the ...
On-line ionic liquid-based preconcentration system coupled to flame atomic absorption spectrometry for trace cadmium determination in plastic food packaging materials
(Elsevier Science, 2009-05)
A novel on-line preconcentration method based on liquid-liquid (L-L) extraction with room temperature ionic liquids (RTILs) coupled to flame atomic absorption spectrometry (FAAS) was developed for cadmium determination in ...
EDTA modified LDHs as Cu2+ scavengers: Removal kinetics and sorbent stability
(Academic Press Inc Elsevier Science, 2009-03)
EDTA modified layered double hydroxides (LDHs) were investigated as potential sorbents to remediate heavy metals pollution. The polidentate ligand was introduced by an exchange method in a Zn-Al-LDH, which takes place with ...
