An ultrasound-assisted extraction procedure for the determination of banned azo dyes in leather

Ahlström, Lars-Henric LU and Mathiasson, Lennart LU (2006) In The Journal of the American Leather Chemists Association 101(10). p.355-361
Abstract
The potential risk for consumers to be exposed to banned azo dyes in leather is strong motivation for the development of an analytical test procedure with improved accuracy. The currently most accepted analytical procedure for this application, the German standard DIN 53316 method, suffers from major drawbacks including low accuracy and the usage of hazardous organic solvents. As a consequence, an alternative procedure based on ultrasound-assisted extraction (UAE) was developed for the determination of banned azo dyes in leather. The optimized UAE procedure was applied to bovine, sheep, and goat leather. These results were compared with those obtained by employing the DIN 53316 method or microwave-assisted extraction (MAE). Usually, the... (More)
The potential risk for consumers to be exposed to banned azo dyes in leather is strong motivation for the development of an analytical test procedure with improved accuracy. The currently most accepted analytical procedure for this application, the German standard DIN 53316 method, suffers from major drawbacks including low accuracy and the usage of hazardous organic solvents. As a consequence, an alternative procedure based on ultrasound-assisted extraction (UAE) was developed for the determination of banned azo dyes in leather. The optimized UAE procedure was applied to bovine, sheep, and goat leather. These results were compared with those obtained by employing the DIN 53316 method or microwave-assisted extraction (MAE). Usually, the performance of UAE was better than the DIN 53316 method and comparable to MAE. Furthermore, the UAE procedure utilizes acidified water as extraction solvent rather than methyl tert.-butyl ether. Because of its simplicity and the inexpensive equipment required, the proposed procedure has the potential to become the preferred alternative for analyzing banned azo dyes in leather on a routine basis.
