Photodegradation of methyl red by advanced and homogeneous photo-Fenton's processes: a comparative study and kinetic approach.

J. Environ. Monit. 11(7) , 1397-404, (2009)

The degradation of methyl red (MR), an azo dye, was carried out by the homogeneous photo-Fenton's process (HPFP) and the advanced photo-Fenton's process (APFP) using symmetrical peroxides such as hydr...

Development of a novel colorimetric indicator label for monitoring freshness of intermediate-moisture dessert spoilage.

Talanta 81(3) , 1126-32, (2010)

A colorimetric mixed pH dye-based indicator with potential for the development of intelligent packaging, as a "chemical barcode" for real-time monitoring of intermediate-moisture dessert spoilage, is ...

Preconcentration of aqueous dyes through phase-transfer liquid-phase microextraction with a room-temperature ionic liquid.

Anal. Chim. Acta 742 , 54-8, (2012)

In this study, we employed the room-temperature ionic liquid [bmim][PF(6)] as both ion-pair agent and an extractant in the phase-transfer liquid-phase microextraction (PTLPME) of aqueous dyes. In the ...
