Utility of cloud-point preconcentration and spectrophotometry for determination of trace amounts of palladium(II) and their analytical applications

Ultrasound-assisted supramolecular dispersive liquid–liquid microextraction based on solidification of floating organic drops for preconcentration of palladium in water and road dust samples

“…The characteristic data of the present method with those reported in the literature is compared and the results are shown in Table 3 [6, [19][20][21][22][23][24]. The proposed method gave low LOD and high enhancement factor with good RSD and these characteristics are comparable or even better than most of the other methods.…”

Selective separation of uranyl ions from some lanthanide elements using a promising β-enaminoester ligand by cloud point extraction

“…25,26 Moreover, the diazo dyes are a very interesting compounds that are frequently used in the spectrophotometric determination of different metal ions. [27][28][29] Due to the high potential of cyclic primary b-enaminones for the separation of metals, a distinctive diazo decorated b-enaminoester has been elaborated in this study for the extraction and preconcentration of uranyl ions.…”
