“…Table 3 contains the ndings of a comparison between optical sensor detection of Pd 2+ ions and spectrophotometric methods. [67][68][69][70][71][72][73][74][75][76][77][78] Unfortunately, there aren't many publications on optical sensors for evaluating Pd 2+ ions. It was established that the achieved optode is signicantly better than a number of available sensors for the monitoring of Pd 2+ ions.…”

“…As shown in the literature [7,8,20,[32][33][34][35][36][37], most spectrophotometric methods of palladium determination are characterized by not very high selectivity towards such cations as Ni(II), Co(II), Cu(II), Fe(III), Fe(II), Ag(I), REE (rare earth elements), platinum metals, and others. We investigated the effect of platinum metals and heavy and alkaline earth metal ions that can be present in the studied samples or can be introduced during dissolution.…”

The simple, rapid spectrophotometric method for palladium(II) ions determination using a new analytical reagent is described. The interaction of Pd(II) ions with a reagent, of the class of azolidones, 4-(N′-(4-imino-2-oxo-thiazolidine-5-ylidene)-hydrazino)-benzoic acid, in water medium results in the formation of a complex. The Pd(II)-p-ITYBA complex shows maximum absorbance at a wavelength of 450 nm. The molar absorptivity is 4.30 × 103 L·mol−1·cm−1. The optimal pH for complex formation is 7.0. The developed method has a wide linearity range of 0.64–10.64 µg·mL−1 for Pd(II). The detection limit is 0.23 µg·mL−1. It was found that Co(II), Ni(II), Zn(II), Fe(III), Cu(II), Al(III), and many anions do not interfere with the Pd(II) determination. The proposed method was tested in the analysis of model solutions and successfully applied for the determination of palladium in catalyst. The obtained results show that this method can be used for serial determinations of palladium in various objects.

“…23 Extraction and spectrophotometric determination of palladium(II) was reported using several organic reagents, summarized in Table 1. [24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39] In continuation of our work on the extractive spectrophotometric determination of PGMs, [40][41][42][43] we have synthesized new sulfur containing ligand, FBIMMT and aimed to develop simple, selective and rapid spectrophotometric method for trace level determination of palladium(II).…”

A simple, rapid and selective method has been developed for the extractive spectrophotometric determination of palladium(II) using 4-(4'-fluorobenzylideneimino)-3-methyl-5-mercapto-1, 2, 4-triazole, (FBIMMT). In hydrochloric acid medium palladium(II) instantly forms stable yellow colored 1:1 complex with FBIMMT at room temperature, which was well extracted in chloroform. The extracted palladium(II)-FBIMMT species showed absorption maximum at 390 nm against reagent blank. The molar absorptivity and Sandell's sensitivity of palladium(II)-FBIMMT in chloroform were found to be 5.404 × 10 3 L mol -1 cm -1 and 0.0196 µg cm -2 respectively. The Beer's law was obeyed up to 17.5 µg mL -1 of palladium(II). The optimal concentration range for maximum precision was evaluated from Ringbom's plot and was found to be 5 to 17.5 µg mL -1 . To establish the optimum extraction conditions; various experimental parameters such as acidity, reagent concentration, solvents, shaking time, interference of cations and anions have been studied. To determine accuracy and precision of proposed method, determinations were carried out at five identical aliquots. The selectivity of the method was enhanced by the use of masking agents. The stoichiometry of the extracted species was assessed by Job's method, mole ratio method and verified by log-log plot. The present method was successfully applied for the separation and determination of palladium(II) from binary mixtures, multi component synthetic mixtures, synthetic mixtures corresponding to alloys and catalyst.
