dc.description.abstractThe determination of minoxidil (MX) with potassium permanganate as a carrier in a flow injection method is described. The detection at 550nm was linear from 1.0x10-5 to 5.0x10-4mol L-1. The limit of detection (3 sigma/slope) was 8.92x10-6mol L-1, with an analytical frequency of 32h-1. The proposed method was applied to commercial samples, with recoveries from 104.7 to 106.4%. Comparison with the HPLC procedure reveled relative errors from 0.48 to 1.4%, and the results agreed within a 95% confidence level.
