Palladium, as a precious metal, plays a very important role in modern industry due to its attractive physical and chemical properties such as excellent corrosion resistance, stable thermoelectricity and high catalytic activity. The computational studying was estimated to approve the geometry of the isolated solid compounds. The mechanism of solvent sublatation of the TBA. This sublation method was applied to real samples and recoveries of more than 95% were obtained in the spiked samples with a preconcentration factor of 100. The coefficient of determination, the limit of detection (LOD) and limit of quantification (LOQ) were 0.9943, 21.29 ngL −1 and 64.5 ngL −1, respectively. At optimum conditions, the linear range of Pd (II) was 10.0–100.0 ngmL −1. Also, palladium is determined directly in the organic phase, which decreases the determination time and its loss during determination. The method involves the determination of trace palladium (II) after selective separation by solvent sublation, thus eliminating the effect of foreign ions and increasing the sensitivity. The different experimental variables that affect the sublation efficiency ( S, %) were thoroughly investigated viz.: pH of sample solution amounts of A1, Pd (II) and TBAB type and amounts of surfactants, types of organic solvent, temperature and stirring time. A combined solvent sublation-ICP OES methodology has been studied for the preconcentration, separation and determination of trace palladium (II) in media of diverse origin using the Schiff base ligand (A1). The prepared compounds were characterized by elemental analysis, Ultraviolet–Visible spectroscopy (UV–Vis), Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), Transmission electron microscopy (TEM) and Thermogravimetric Analysis (TGA). A novel nano-palladium (II) Schiff base complex (C1) is synthesized by the reaction between palladium chloride and the Schiff base N, N’-1, 2-phenylene) bis (3 -aminobenzamide (A1).
