Abstract
The study involved the preparation and diagnosis of new Ligand is 2 - (4 - methoxy-phenyl)azo [5,4- diphenyl imidazole ] (MPAI), one of the azo compounds. And that of the traditional method of alazoth . The study also considered the use of this reagent to express spectroscopy for copper ion in the binary solution of water , where it was noted that the reagent be complicated The color orange with the ion and shows the greatest absorption at λ max= (415) nm (pH = 8). Was found to be acomplexcopper duo Reagent with a stable of more than (24hours) when the pH best with compliance to Beer's law in the range of concentrations ranging between (1.2598x10-5 -1.2598x10-4 M) . The effect of several factors , including the value of the absorption effect of reagent concentration , reaction time, masking agent , sequences of addition and the effect of different parameters such as effect cations and anions ,and the effect of ionic strength and temperature effect . the stoichiometry of complex was investigated by ratio of the reagent - metal molar ratios, Jobs ( the constant changes ) molard methods showed that the proportion of the metal regent is (1:2) . As has been the preparation of complex solid was studying some of his physical characteristics such as solubility and molar conductivity and the melting point of the complex . All compound has been characterized by spectroscopic methods [FT.IR.,UV-Vis].(UV-Vis) absorption spectra show bathochromic shift ( compared with that of free reagent ) the results of the accuracy and precision of the method used to estimate the value of the element copper percentile relative deviation (RSD%) ranged between(0.534% -2.903%) while the values of the relative error( E%) between ( -7.943 % -4.033%).
