Abstract
Petroleum refinery
wastewater containing a range of aliphatic and aromatic organic compounds was
treated using nanotitania particles, as the photocatalyst in UV/TiO2
process. Samples were collected from the inlet point of the biological
treatment unit.
A maximum reduction in
chemical oxygen demand (COD) of more than 78% was achieved after about 120 min. Significant pollutant
degradation was also relevant under other conditions. The identification
analysis of the organic pollutants, provided by means of a GC/MS, equipped with
headspace injection technique, showed that different petroleum compounds were
degraded with high efficiencies.
