A presença do ânion sulfeto (S2-) em diversos tipos de águas é indesejável devido a sua alta toxicidade e poder corrosivo. Além disso, seu odor desagradável característico – devido a formação de H2S – pode ser percebido pelo olfato a pa

3D-printed and fully portable fluorescent-based platform for sulfide determination in waters combining vapor generation extraction and digital images treatment

Autor: Alex D. Batista, João Flávio da Silveira Petruci, Vanderli Garcia Leal

Publikováno v: Talanta. 222

The determination of sulfide anion in a variety of waters (e.g. wastewaters and natural waters) even at low concentration (i.e. in the μM range) is essential due to its high toxicity, corrosivity and unpleasant smelling proprieties. Despite several
