TL;DR: In this article, an overview of the state of development of analytical procedures for the determination of such azo dyes, which are banned by the European Commission, can be found.

TL;DR: In this paper, an analytical procedure based on microwave assisted extraction (MAE) and standard addition was applied for the determination of banned azo dyes in bovine, sheep, and goat leather.

TL;DR: The possibility of improving an existing method, based on supercritical-fluid extraction and microwave-assisted extraction, for the determination of banned azo dyes in leather has been studied and the present method gave significantly higher recoveries in comparison with the original method.

TL;DR: An analytical procedure based on supercritical-fluid extraction and microwave-assisted extraction was applied on six different real leather samples for the determination of banned azo dyes and showed that the latter quantification method provided the highest accuracy.

TL;DR: In this paper, two approaches based on alkaline hydrolysis, in combination with either stir-bar sorptive extraction (SBSE) or sonication, were developed for the determination of banned azo dyes in bovine leather.
