Innovative integrated process for the treatment of azo dyes: coupling of photocatalysis and biological treatment
... of the intermediate by-products is in progress to propose a reaction pathway. The feasibility of the use of an integrated process involving photocatalysis followed by biological treatment for dye degradation is confirmed. A biodegradation of the by-products resulting from the photocatalysis ste ...
