How to reduce the amount of MnO2 generated from titration of a solution of PAA (peracetic acid, acetic acid and H2O2) with KMnO4?

To determine the content of H2O2 in PAA solution, I did the titration experiment of PAA with KMnO4 0.05M. Sample solution: 10mL PAA solution + 50mL deionized water+ 5mL H2SO4 1:5. Normally, the...
