Caracterização de resíduos inorgânicos gerados nos laboratórios da UTFPR-PG

Abstract

At the university level the waste generated is smaller in scale compared to industry, but the environmental impacts caused are large if not treated correctly. In order for the correct treatment of the waste to be made before its final destination, it is necessary to know its physical and chemical characteristics. In UTFPR - Campus Ponta Grossa was implemented in 2008 the separation of the residues in chemical groups and to date there is no history of analyzes to characterize them. The purpose of the present work is to quantify, classify and qualify the inorganic residues generated in the physicochemical and quantitative and qualitative analytical chemistry laboratories of UTFPR - Campus Ponta Grossa, through physicochemical and instrumental analyzes. The analyzes were performed separately for each laboratory and made in triplicates. Volumetric, gravimetric and spectrophotometric methods were applied. The results obtained through the analyzes identified that most of the inorganic residues analyzed are composed of water. Due to these results before their final destination a study is suggested for the use of an evaporimeter, to reduce in volume this waste, facilitating the storage and reducing eventual costs that may come to the university by the company that collects that waste.
