Abstract
2-(4-biphenyl)imidazo[1,2-]pyrimidine-3-hydrazone (BIPH) is synthesized and used as a new complexation analytical reagent in quantitative determination of copper ions, a yellowish green complex is resulted from this reaction. At the beginning, the reaction conditions were optimized at 430 nm which is the maximum wave length 〖(λ〗_max) of the complex. The linear concentration range is 0.05-500ppm and the limit of detection is 0.122 ppm.
To test validity of this determination method, it was applied on samples with different matrix, and copper ion concentrations such as life samples of urine, tap water, wastewater and industrial samples of 4%copper alloy and 99%copper alloy. Standard addition method is also used to avoid matrix effect on analytical results. In application of suggested method, the values of relative error were (-4.536)–2.071% and values of recoveries were 95.46-102.07%.
The high stability constant of resulted complex (K=0.25×108), and the simplicity in procedure of complex preparation, both provided us a motivation to prepare complex, and to study some of its characteristics by performing the identified analyses such as FTIR, UV-Visible spectroscopy, SEM+EDX, conductance measurement, reflectance percent R% to enrich the proposed structure of complex.
