ABSTRACT: The removal of oil pollutants from water and purifying
process of oil-polluted water are studied through catalytic degradation method
with nano-MgO. The results indicated that catalytic degradation effect of
nano-MgO on the oil pollutants was associated with dosage of nano-MgO, pH and
water temperature. When oil content was 1.8 mg/L, 0.17 g nano-MgO was used
and the removal rate of oil was 93.92%. Furthermore, nano-Mgo was a
non-photosensitive catalyst. GC/MS analysis showed that the amount of
petroleum-based pollutants in water was reduced 73.77% from the previous 61
kinds to 16 kinds, and the total peak area was reduced 96.05% after catalytic
degradation of nano-MgO. Therefore, nano-MgO has an excellent effect on the
catalytic degradation of oil pollutants and can be applied in the treatment of
oil wastewaters.
