I do not have a lot of knowledge about peroxidases, but I do know that there are _many_ different types of peroxidases in all sorts of plants. The differences between them will include different optimal pH and temperature values, so unless you found experimental results online from the exact same potato peroxidase, you cannot really compare them to your results. If you are confident that you performed the experiment correctly, then your results are probably reasonable for the peroxidase you were testing.
I am not sure about whether or not alcohol and NaCl can activate peroxidases.
Hope some of this helps!
