The IBP ,degradation, sharply increased with an increasing catalyst dose from 0.2 until an optimal value of 0.5 g L-1. A further increase of magnesium ferrite concentration up to 1.0 g L-1 was affected positively only at the first 20 minutes. Intrestingly, IBP ,degradation, efficiency were equal for the catalytic reaction time of 30-40 min.
