Highly sensitive procedure for the determination of ultra-trace amounts of bromate ions in water by dispersive liquid-liquid microextraction combined with UV-Vis spectrophotometry

Fluorescence enhancement of rhodamine B as a tool for the determination of trace and ultra-trace concentrations of bismuth using dispersive liquid–liquid microextraction

“…7 Alternatively, low cost methods such as spectrophotometry and/or spectrouorimetry combined with microextraction techniques have been efficiently used for metal ions determination at trace and ultratrace concentrations and using small volumes of samples. 8 Among microextraction techniques, dispersive liquid-liquid microextraction (DLLME) introduced by Assadi et al in 2006 has found wide range of applications to the analysis of heavy metals, pesticide residues and so on [9][10][11][12] due to easy to apply and excellent analytical performance compared to other microextraction techniques.…”
