Cloud point extraction and spectrophotometric determination of mercury species at trace levels in environmental samples
(2012)
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) ...
Surfactant enhanced-spectrophotometric determination of uranium (VI) at trace levels by using eriochrome black T as a chelating agent
(2011)
A sensitive and relatively selective spectrophotometric method is proposed for the rapid determination of uranium using Eriochrome Black T (EBT) being a 2, 2'-dihydroxy azo benzene derivative metal indicator in the presence ...
