Abstract
In a weak acidic medium, the reaction of some aminoglycoside antibiotics (AGs) such as kanamycin sulfate (KANA), gentamycin sulfate (GEN), and tobramycin sulfate (TOB) with acid thiazolyl bisazo dye Titan Yellow (TY) can result in the fading of TY. The maximum fading wavelength was located at 409 nm. The molar absorptivities (ɛ/×104 1 mol−1 cm−1) were 2.0, 1.5 and 2.5 for KANA, GEN and TOB, respectively. The spectral characteristics, effect factors, optimum conditions of the reaction and the influence of foreign substances were also investigated. The procedure is easy and fast. This method has high sensitivity and can be applied to the determination of commercial aminoglycoside antibiotics and serum samples with satisfactory results.
