Synthesis, Characterization and Thermogravimetric Study of Some Metal Complexes of Selenazone Ligand Nanoparticles Analogue of Dithizone

A new method for preparing 1,5-diphenylselenocarbazone (selenazone) nanoparticles and their complexes with Pb2+, Cd2+, Co2+, Ni2+ has been performed using hot methanol solvent. The ligand its were characterized FT-IR, UV-Vis, 1H-NMR, 13C-NMR, X-ray powder diffraction (XRD), EI-mass spectrometry, scanning electron microscopy (SEM), HG flame-atomic absorption spectrophotometer, thermal analysis (TG/DTA), molar conductance measurements. measurements in all recorded low values DMSO, indicating that the metal non-electrolytes except nickel complex possessed an electrolytic nature. Kinetic thermodynamic parameters of (A, E, ∆H, ∆S, ∆G) have computed three kinetic models Coast-Redfern, Broido, Horowitz-Metzger, illustrated decomposition reactions steps nonspontaneous. Thermogravimetric analyses (TG/DTA) consistent atomic spectroscopy data proving geometry shape was octahedral.
