A Method for Determination of Ammonia in Air using Oxalic Acid-Impregnated Cellulose Filters and Fluorimetric Detection
(Soc Brasileira Quimica, 2012-01-01)
A fluorimetric method was developed for the determination of ammonia in ambient air. Samples were collected using cellulose filters impregnated with oxalic acid, followed by solubilization of the ammonium ion, addition of ...

Nylon membrane as a fluorimetric probe for the herbicide bentazone
(Springer Heidelberg, 2012-01)
The fluorimetric signal produced by bentazone retained in selected solid surfaces was investigated. Among the different tested supports, only a microporous nylon membrane produced the desired signal. The quantitative study ...
A Method for Determination of Ammonia in Air using Oxalic Acid-Impregnated Cellulose Filters and Fluorimetric Detection
(Soc Brasileira Quimica, 2014)
A second-order fluorimetric approach based on a boron dipyrromethene tetraamide derivative for Hg(II) chemosensing in water and fish samplesSecond-order fluorimetric approach based on a boron dipyrromethene (BODIPY) tetraamide derivative for Hg(II) chemosensing in water and fish samples

A second-order fluorimetric approach based on a boron dipyrromethene tetraamide derivative for Hg(II) chemosensing in water and fish samples
(Royal Society of Chemistry, 2014-11)
A new fluorimetric method is described for the determination of Hg(II), based on the selectivity of a boron dipyrromethene tetraamide derivative (BODIPYTD) towards this ion, in combination with second-order chemometric ...
Fluorimetric determination of fluoride in a flow assembly integrated on-line to an open/closed FIA system to remove interference by solid phase extraction
(Elsevier Science, 2002-11)
A simple flow injection fluorimetric method for fluoride determination is proposed. The method is based on the enhanced fluorescence of quercitin-Zr(IV) complex when fluoride ion is present in the sample. An open/closed ...
Brazilian reference values for MPS II screening in dried blood spots - A fluorimetric assay
(Elsevier B.V., 2014-09-01)
Objectives: Mucopolysaccharidosis II (MPS II), or Hunter Syndrome, is a lysosomal storage disorder that is caused by the deficiency or absence of iduronate-2-sulfatase (IDS) enzyme; in this disease, early diagnosis is ...
Photoinduced electron transfer fluorimetric Hg(II) chemosensor based on a BODIPY armed with a tetrapod receptor
(Elsevier, 2013-09)
From the great variety of BODIPY based-chemosensors able to determine Hg2+, only a small portion has been applied to its determination in environmental and/or biological samples. The lack of studies on the analytical ...
