Azo dyes

The aim of the presented work was the investigation on the possibility of application of the hybrid photocatalysis/membrane processes system for removal of azo dyes (Acid Red 18, Direct Green 99 and Acid Yellow 36) from water. The photocatalytic reactions were conducted in the flow reactor with immo

Tests of the biodegradation of the azo dyes Reactive Black 5 and Reactive Yellow 145 confirmed the low biodegradability of these components in the considered conditions, namely a strain of Pseudomonas fluorescens, cultivated at 25°C, an initial pH of 7 and in presence of a supplementary carbon sourc

A systematic approach was followed to optimise pH, temperature and the doses of FeSO4 and H2O2 for Feton’s reagent (FR) to decolourize and detoxify the solutions containing of Remazol Red 120 (RR) dye and its mixture with Remazol Brillant Blue (RB) and Remazol Yellow 84 (RY) reactive dyes. The acute
