It is possible to have an activated carbon with pH pzc = 7.5 when the Boehm titration indicates 1.5 mmol/g acidic groups and 0.5 mmol/g basic groups?

I have determined a neutral value for the pHpzc of an activated carbon. By Boehm titration the results indicates that the surface of the activated carbon contains more acidic oxygenated groups...
