Evaluation of Antimicrobial Activity and Study of Raman Spectra for Malachite Green Dye in Aquaculture in Solid State and Liquid State

This papers include the study of Raman spectra for different forms (solid and liquid) of the malachite green dye. Three concentrations (10^-3,10^-4,10^-5) Ml of dye solution are prepared in the water solvent and Raman spectra were measured using a wavelength laser beam (532 nm) A total of (11) major vibration patterns were obtained for the dye in concentration (10^-3) and (6) vibration patterns in concentration (10^-4) while the number of vibration patterns (5) in concentration (10^-5) Using a (pld) technique, a solid form(film) of dye was prepared on its own, When Raman spectra was measured, (8) vibratory patterns appeared, while the vibration patterns of dye were decreased when the dye film was prepared with the polymer. Vibration patterns were observed in all models prepared The most prominent (C-N str,C-H ben,C=C str).
