Cibacron Yellow

RP-HPLC was also employed for the investigation of the hydrolysis behaviour of two fluorotriazine reactive dyes Cibacron blue F-R and Cibacron yellow F-4G. Chromatographic measurements were performed in an ODS column (50 X 4.6 mm i.d. particle size 5 /jm) at room temperature. The mobile phase was ACN-0.05 M ammonium acetate buffer containing 1 mM acetyhrimethylammonium bromide (47 53, v/v). Flow rates were 0.8 and 0.6 ml/min depending on the dyes to be separated. Dyes were detected at 275 nm. The hydrolysis of dyes was investigated both in the absence and presence of... 

Fig. 3.124. Chromatograms of a 1 1 dye mixture (a) 40 min before addition of Na2C03, (b) 10 min after addition of Na2C03, and (c) 60 min after addition of Na2C03 flow rate = 0.6 ml/min, other conditions are described in the text. The peak at 4.57 min in (a) and the same peak (smaller in size) at 4.54 min in (b) are both attributed to the functional group of cibacron yellow ( — F) the peak at 7.54 min in (a) and the same peak (smaller in size) at 7.40 min in (b) are both attributed to the hydrolysed part of the functional group of cibacron yellow the peaks at 5.07 min in (b) and 5.22 min in (c) are attributed to the hydrolysed part of the functional group of cibacron blue.

The decolourization capacity of the white-rot fungus Phlebia tremellosa was investigated in detail. Dyes included in the experiments were Cibacron red, Remazol navy blue, Remazol red, Cibacron orange, Remazol golden yellow, Remazol blue, Remazol turquoise blue, and Remazol black B. The decomposition of Remazol black B was followed by RP-HPLC. Measurements were performed in an ODS column (250 X 4.6 mm i.d.) using ACN-water...
