A new method to determine the concentration of amikacin (AMK) using methyl blue (MB) as electrochemical probe was developed in this paper. In pH 4.5 Britton-Robinson (B-R) buffer solution, the MB reacted with AMK to form ion association complexes, which led to the reductive peak current of MB at -0.275 V (versus SCE) to decrease, and the decreases were linear with the concentration of AMK in the range of 1.0-60.0 mg/L, the regression of equation is AIp (nA)=-8.48+102.36c (mg/L),correlation coefficient γ is 0.997. The conditions for determining the concentration of AMK using linear sweep voltammetry (SLV) were optimized. The method was used to determine the content of amikacin commercially available with satisfactory results.
