Abstract

V originále

Monitoring the hydrolysis of Ostazine Black V-B reactive dye was found to be possible by matrix-assisted laser desorption/ionisation time-of-flight mass spectrometry (MALDI-TOFMS). All the desired substances were identified in a mixture of the dye-bath. The process of the substrate reactive dye hydrolysis was qualified with hydrolysis rate constants k1 (2.0 +/- 0.3 E-1) and k2 (0.6 +/- 0.1 E-1). The method developed is important for the dyeing industry and for following the colouration process.
