Colorimetric and test-determination of
tetracycline and doxycycline in milk and milk products after sorption
concentration at chemically modified aluminosilicate
Abstract
The technique of colorimetric and
test-determination of tetracycline and doxycycline by reaction with iron(III)
on the surface of chemically modified aluminosilicate was developed. The
advantage of the technique is the rapidity, ease of performance, affordability
and good metrological characteristics. The method can be used in the practice
of laboratories performing chemical analysis of foodstuffs.
Key words: tetracycline, doxycycline,
aluminosilicate, colorimetry, milk and milk products.
