Micro-funnel magnetic stirring-assisted liquid–liquid microextraction technique combined with UV–Vis spectrophotometry for determination of thorium in aqueous samples with the aid of experimental design

In this study, trace amounts of thorium ions were extracted using a highly sensitive, selective, rapid and simple micro-funnel magnetic stirring-assisted liquid–liquid microextraction method, and determined by UV–Vis spectrophotometry. Tri-n-octylphosphine oxide was used as the complexing agent duri...
