Abstract
To evaluate the release kinetics, in a simulated body fluid, of tobramycin (TOB) from carbonated apatite (CHA) in the form of granulate, a sensitive and reliable liquid chromatographic method was developed. Chromatographic separation was performed on a Metrosep Carb 1 anionic column by using 0.1 M NaOH as mobile phase at a flow rate of 1.0 ml min− 1. TOB was quantified by pulsed amperometric detection using a 3-potential waveform on Au electrode. A linear relationship for TOB was found in the range 0.17–2.50 mg l− 1 with a LOD of 0.05 mg l− 1. The method exhibited good retention time and peak area reproducibility.
