Evaluation of the composition of electronic waste hard disk using spectroanalytical techniques: proposition of fast and simple methods
(Universidade Federal de São Carlos, 2020-12-17)
The electronic waste is a worldwide problem of great magnitude with 53.6 Mt of waste generated in 2019. Unfortunately, the recycling rate is still very low. It is estimated that only 2% of the electronic waste is recycled ...
Investigação da eletrodeposição de ligas de Zn-Fe-Mo e caracterização química, estrutural e morfológica dos filmes
(Universidade Federal de São Carlos, 2021-08-19)
In this work, an alkaline bath for electrodeposition of Zn-Fe-Mo alloy containing glycerol was developed. Potentiometric titration of the Fe3+/glycerol bath showed that soluble Fe(III)-glycerol complex was formed at pH > ...
