Inexpensive and versatile method for trace Sn(II) and Sn(IV) ions in food samples by CPE/FAAS
(2012)
In this work, a new cloud point extraction procedure was developed for the separation and preconcentration of tin ions in water and food samples. The method is based on the complexation of Sn(IV) ions with calcon carboxylic ...
Determination of ultra trace arsenic species in water samples by hydride generation atomic absorption spectrometry after cloud point extraction
(2011)
Cloud point extraction (CPE) methodology has successfully been employed for the preconcentration of ultra-trace arsenic species in aqueous samples prior to hydride generation atomic absorption spectrometry (HGAAS). As(III) ...
