A Simple and Green Analytical Method for the Determination of Formaldehyde
(Soc Brasileira Quimica, 2008-01-01)
A green spectrophotometric analytical method for determination of formaldehyde in commercial samples was designed and investigated. Replacement of hazardous reagents was explored to attain the clean chemistry standards. ...
Analytical chemistry in a liquid film/droplet
(1995-12-01)
The measurement of nitrogen dioxide at the parts-perbillion level is described. The experimental arrangement consists of two optical fibers placed on opposite sides of and in contact with a liquid film (14-57 μL in volume) ...

Surface-enhanced Raman scattering (SERS) applied to cancer diagnosis and detection of pesticides, explosives, and drugs
(2013-02-01)
The inelastic scattering of light, Raman scattering, presents a very low cross section. However, the signal can be amplified by several orders of magnitude, leading to the so-called surface-enhanced Raman scattering (SERS) ...
Contaminação ambiental por compostos organoestânicos
(Sociedade Brasileira de Química, 2003-10-01)
The occurrence and the effects of organotin compounds (OTs) have been studied since a long time, due to their widespread use and deleterious effects. Some OTs are used as pesticides in crops, or as biocides in antifouling ...
