N. Koprivanac et al., MONITORING THE CI REACTIVE-RED-120 PROCESS BY THIN-LAYER CHROMATOGRAPHY WITH DENSITOMETRY, Journal of environmental science and health. Part A: Environmental science and engineering, 32(9-10), 1997, pp. 2553-2562
The two-step reaction of the C.I. Reactive Red 120 (RR120) production
was monitoring by thin-layer chromatography with densitometry. The obt
ained intermediate C.I. Reactive Red 1 (RR1), hydrolized by-products a
nd final product RR120 were separated and quantificated. The productio
n costs and the pollution of wastewater were significantly decreased b
y optimization of the RR120 process.
