Spectrophotometric Determination of Micro Amount of Nickel (II) Using an (Azo) Derivative in the Presence of Surfactant, Study of Thermodynamic Functions and Their Analytical Application

Abstract

It is characterized as a nickel spectrophotometric approach that is very sensitive and substantially interference-free. For the study of Co (II), Mn (II), and other metals in this complex, the imidazole azo ligands (DPIDA) were produced and Mn (II), Co (II), and other metals in this complex were analyzed. Ni (II), "Cu" (II), Zn (II), Cd (II) and Hg (II) ions are among the most important azo ligands in the area of coordinated chemistry. First, molarity and 1HNMR spectroscopy were carried out. To explain their conductivity, we must take into account the fact that they have octahedral geometry with a bidentate ligand coordinated by an imidazole (N3) and an azo group (O)-atom. In addition, the thesis examined the use of Reagent was employed in binary water solution to conduct spectroscopy with nickel (II) ion, and it was discovered that the reagent is difficult to the ion and has the maximum sensitivity. 530.55 nm (pH = 8) is the absorption wavelength. A dynamic nickel-pair reagent with more than 24 hours of stability was found in the concentration range of (0.1–2.5 g/mL) by Beer's law. masking agent and concentration all have an impact. Stoichiometry with molar reagent-metal ratios as well as the effects on the absorption of cations and anions, as well as the effect of ionic strength and temperature were explored in these studies (the constant changes). According to the mallard equation, the molar absorptiveness of metal reagent (1:2) is (2.4x104 L. mol-1. cm-1). It is possible to detect (0.004 microns/ml) and quantify (0.627 microns/ml) using the same detection and quantification limit values. This dynamic nickel pair was more stable, with a more soluble molecular conductivity and a lower melting point (0.1–2.5 g/mL) in the range of pH conformance (0.1–2.5 g/mL). FT.IR. and UV-Vis spectroscopy methods have been used to classify both compounds. Comparing free reagent spectra to bathochromic transition (UV Vis), it can be seen that the approach used to compute nickel per cent deviation is very precise and accurate (RSD per cent). the relative error (E per cent) deviated from the standard deviation (SD) (4.011 per cent, 0.803 per cent). Temperature also had a role in determining the thermodynamic functions (H, G, S). With great accuracy and precision, the method was applied to a variety of environmental and industrial models.
