The demand for palladium (Pd) has increased and this made it necessary to recover pure Pd from diverse secondary resources. To the small amount of Pd(II) present in spent electroplating solutions, is concentrated by cementation with zinc metal. In work, a hydrometallurgical process consisting leaching solvent extraction was developed cemented Pd. behavior Zn(II) synthetic HCl solution commercia...

Abstract Stability and structure of complexes between silver (I) l -methionine (L) deduced from potentiometric 1 H NMR measurements allow to assume the prevailing several protonated species. The experimental data are compatible with formation following complexes: AgL, AgL 2 , AgH L, L 3 4 . coordination sites obtained by spectra, showing that only bond methylthioether sulfur atom is responsible...

The optimization of micropropagation for blueberries is crucial due to the growing blueberry industry and demand plantlets. This study focused on four stages: explant sterilization, in vitro establishment, proliferation, ex rooting, aiming establish an efficient propagation system southern highbush cultivar ‘ZY09’. most effective sterilization method was a 60 s treatment with 75% ethanol 5 min ...

Aqueous salt batteries with high concentrations of or water in aqueous systems have received considerable attention focus on improving working voltage range and energy density. Here, the effect NaClO 4 concentration electrochemical performance stability tunnel-type Na 0.44 MnO 2 (NMO) cathodes organic polyimide (PI) derivative anodes was studied. High capacity retention 100% coulombic efficienc...

We examined the changes in physicochemical quality characteristics and antioxidant activity of fresh-cut Fuji apples (Malus pumila) during processing storage after treatment with browning inhibitors. The primary aim was to elucidate suitability storability. observed that stage slicing fresh apples, there were no significant differences 1,1-diphenyl-2-picrylhydrazyl (DPPH) 2,2′-azinobis (3-ethyl...

The complexation of uranium(VI) and samarium(III) with oxydiacetate (ODA) in 1.05 mol kg(-1) NaClO(4) is studied at variable temperatures (25-70 degrees C). Three U(VI)/ODA complexes (UO(2)L, UO(2)L(2)(2-), and UO(2)HL(2)(-)) and three Sm(III)/ODA complexes (SmL(j)((3-2)(j)+) with j = 1, 2, 3) are identified in this temperature range. The formation constants and the molar enthalpies of complexa...

The speciation of Eu complexed with polyacrylic acid (PAA) and alumina-bound PAA (PAA(ads)) was studied at pH 5 in 0.1 M NaClO(4). Structural parameters were obtained from (7)F(0) -->(5)D(0) excitation spectra measured by laser-induced fluorescence spectroscopy as well as from Eu L(III)-edge extended X-ray absorption fine structure (EXAFS) spectra. The coordination mode was also investigated by...
