Development of a cloud point extraction and preconcentration method for chromium(III) and total chromium prior to flame atomic absorption spectrometry
A sensitive and selective method has been developed for the determination of chromium in water samples based on using cloud point extraction (CPE) preconcentration and determination by flame atomic absorption spectrometry ...
Cloud point extraction and spectrophotometric determination of mercury species at trace levels in environmental samples
A new micelle-mediated separation and preconcentration method was developed for ultra-trace quantities of mercury ions prior to spectrophotometric determination. The method is based on cloud point extraction (CPE) of Hg(II) ...
Inexpensive and versatile method for trace Sn(II) and Sn(IV) ions in food samples by CPE/FAAS
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 ...
