Didactic Transposition Of Treatment Method Of Water With Activated Carbon For Estradiol Separation

Abstract

This producion deals with a didactic transposition for teaching Chemistry, as a proposal for a didactic sequence (SD), which involves Carbo activatus as an adsorption method, providing removal of endocrine disruptors - the female hormones 17β-estradiol and 17α-ethinylestradiol, present in wastewater. The detection of endocrine disruptors has become increasingly evident in research related to water, increasing the interest in knowing the effects of these substances on living organisms and ways to perform their treatment in the environment. Current studies related to disruptors show their presence in an aqueous medium, and already consider the possibility, even in small amounts, of interfering with both the health of aquatic and human fauna. The data for the construction of the didactic sequence proposal were established in a survey carried out in 2017 and which culminated in the proposal presented in this article. Therefore, the process of didactic transposition is considered the possibility of scientific knowledge being problematized in taught knowledge, based on research methods and techniques and analytical technical data.
