Cellophane films containing diazo dye for application to high - dose dosimetry have been reported [7], blue cellophane was examined as a monitor of high dose ranges from 10 to 300 kGy and also in electron beam dose profiles.

We tested the precipitates for in vitro decolourisation of Orange G, a monoazo dye, and Congo red, a diazo dye. The results obtained showed that the protein precipitate containing 450 U [L.sup.-1] of laccase activity was able to decolourise all the tested dye that can be seen in Figures 6(a)-6(c), with the decrease in the spectrum at the maximal absorbance of the dye (arrow) after 19 hours.
Congo Red is an example of diazo dye, and the initial pH influences the molecular form of Congo Red in the aqueous solution.

AbstractAn attempt has been taken to decolorize and mineralize Ponceau S (PS) a diazo dye in aqueoussolution by Fenton process.
It was observed that the colour removal yield with the more complex diazo dye (Remazol black B) was, however, much lower than that obtained with the monoazo dyes (Remazol Brilliant Orange 3R and Remazol Brilliant Violet 5R).
I learned a lot about dyeing cloth and yarns but, after one semester, I was driven out of the textiles lab by what turned out to be a sensitivity to diazo dye powders.
