The specialized twin-solution method for selective Pd(II) ions determination and methyl orange removal

The proper determination of Pd(II) ions in the presence Pt(IV) a waste solution is an intricate analytical issue. Having knowledge about composition, we are able to properly design processes and their selective separation recovery. Other important aspect related dyes removal coming from textile industry, which still not resolved. To solve these issues, this work, propose twin solution, describes specialized method allowing for both methyl orange removal. These take place range tautomeric equilibrium (pH = 3 – 5). In order follow process cyclopalladated compounds formation, UV–Vis spectra were registered at different conditions, i.e. pH, temperature as well anions: Cl ̅ ClO4̅ cations: Na+, K+, Pt4+, Pt2+, Co2+, Ni2+, Zn2+, Cu2+. developed distinguished by high sensitivity selectivity, even ions. Moreover, palladium content can be determined using spectroscopy two wavelengths, 560 702 nm 50°C. This extends possibility metal detection cations having similar wavelength ranges. It also concluded, that possible only water: obtained product unstable forms easy-filtratable blue/purple coloured precipitate.
