| Abstract | dc.description.abstract | The present study shows the formation and characterization of the ionic-pair between the antibiotic
oxytetracycline and the dye crystal violet in ammonia solutionpH9.0±0.2 extracted into chloroform. The
characterization was demonstrated using UV–vis spectrophotometry, 1H NMR, measurement of relaxation
times T1 and IR spectroscopy, using a comparison between the signals of individual pure compounds
with the signals with the mixture CV–OTC in different alkaline media. The formation of ionic-pair was
also corroborated by new signals and chemical shifts. (2D) NMR spectroscopy experiments show that the
interaction is electrostatic. | en_US |
