Identificação espectroscópica no ultravioleta de amoxicilina em meio aquoso: uma experimentação contextualizada para o ensino de química na graduação

Abstract

This technique of identification is very widespread both in the field of Analytical Chemistry and in other areas, for identification and drugs and their metabolites. Firstly, a questionnaire was applied to measure the students' previous knowledge of the curricular component of Instrumental Analytical Chemistry. It was observed the lack of knowledge of the students regarding the presence of drugs in effluents, as well as the lack of knowledge of some concepts related to instrumental analysis and contents of Organic Chemistry. From this result was proposed a contextual experimentation using samples of water from the Bagé stream and samples with addition of standard to demonstrate the importance of Analytical Experimental Analytical Chemistry, a component not offered in the curricular structure of the undergraduate course in Chemistry - UNIPAMPA - Campus Bagé, by applying the wavelength determination technique in the ultraviolet region to unknown samples having a standard for comparison. Subsequently the same questionnaire was applied to observe the impact on learning with the application of the experimentation and the contextualization in the graduation.
