Theoretical model for spectroscopic study of Cu+2, Co+2, and Fe+3 dissolved in ethanol with a different concentrations

الملخص EN

The orption spectrum for three types of metal ions in different concentrations has been studying experimentally and theoretically.

The examination model is Gaius model to find the best fitting curve and the equation controlled with this behavior.

The three metal ions are (Copper chloride CuCl3, Iron chloride Fe2Cl3, and Cobalt chloride CoCl3) with different concentrations (10-4, 10-5, 10-6, 10-7) gm/m3.

The spectroscopic study included UV-Visible and fluorescence spectrum for all different concentrations sample.

The results refer to several peaks that appear from the orption spectrum in the high concentration of all metal ions solution.

The multiple orption peaks continued even at the lowest concentration in the iron ion solution.

Fluorescence spectrum shows intensive stimulating of the radiation strength was perceived in the manifestation of Cu+2, Co+2 and Fe+3.

From modeling investigation, there are converge between experimental and theoretical results of the fluorescence spectrum for metal ions.

Furthermore, identity and convergence which defined as (r2), are on average (0.

995).
