Simultaneous determination of acesulfame-K and aspartame using linear sweep voltammetry and multivariate calibration

► A simple and rapid method to determine acesulfame-K and aspartame was proposed. ► The method was applied to power sweeteners without pretreatment. ► Linear sweep voltammetry with a rotating disk electrode was employed. ► Overlapping signals were resolved with multivariate calibration tools. ► Application and validation studies with real samples were satisfactory.
