2.  Synthesis and Characterization of New Metal Complex Dye

Authors: M.E. Radulescu-Grad, S.G. Muntean, A. Todea, O. Verdes and A. Andelescu


Abstract:

The present paper describes the synthesis of a new complex dye formed by an acid dye, Acid Orange 7 (C.I. 15510) with a metallic ion (Cu2+). The resulted compound was characterized via physico-chemical methods FT-IR, UV-VIS, AAs spectroscopy and thermal analysis. The obtained complex dye may have a good affinity for wool, natural silk, leather, and polyamide fibres. Self association of the complex has been investigated by spectroscopic studies, as a function of its concentration.


Keywords: Acid Orange 7, metallic complex dye, aggregation, copper
