Simultaneous determination of thorium and uranium in mineral fertilizers by inductively coupled plasma optical emission spectrometry
(2016-04-01)
The simultaneous determination of thorium and uranium in mineral fertilizers by inductively coupled plasma optical emission spectrometry (ICP OES) was optimized. The three-level factorial design was applied to optimize the ...
Simultaneous determination of copper and iron by solvent extraction and first derivative spectrophotometry
(1995)
A simple, sensitive and selective first derivative spectrophotometric method has been developed for the determination of copper and iron in mixtures. The method is based on the recovery of the analytes, by liquid-liquid ...
Simultaneous determination of o- and p-nitrophenol by first derivative spectrophotometry
(Kluwer Academic Publishers, 1999)
A simple method by first derivative spectrophotometry is proposed for the simultaneous determination of o-nitrophenol and p-nitrophenol. The analytes were separated from samples by liquid-liquid extraction (pH = 7.4) as ...
