I have been looking for a paper that by using spectrophotometry method, we can determine rate of reaction of colourant. I could not find any paper. I was wondering if any body could help me.

$\begingroup$ What do you mean by "colorant"? Please clarify this a little more. $\endgroup$– tschoppiMar 28, 2014 at 13:40

$\begingroup$ @tschoppi I mean dye or pigment... $\endgroup$– Babak MiraftabMar 28, 2014 at 13:43

$\begingroup$ So basically you're looking for a paper about spectrophotometry per se...? I think that is a very broad question... $\endgroup$– tschoppiMar 28, 2014 at 14:14

$\begingroup$ What do you mean for a "reaction of colorant"? A reaction with what? $\endgroup$– G MMar 28, 2014 at 14:34

$\begingroup$ @GM For instance, degradation or formation colourant $\endgroup$– Babak MiraftabMar 28, 2014 at 14:53

I'm not sure I have answer to your question maybe, if you consider natural colorant too, these are the articles that go more close to what you want:
Prediction of phenolic compounds in red wine fermentations by visible and near infrared spectroscopy
Spectroscopic, stability and radical-scavenging properties of a novel pigment from gardenia
Try to have a look a these too:
