Advanced Nanotechnology-Based Approaches to Waste Water Purification from Organic Pollutants

Abstract

One of the organic substance that requires wastewater treatment before being discharged into the aquatic system is phenol and its derivatives, which are known to be endocrine disruptors. Heterogeneous photocatalysis using titanium dioxide and ultraviolet radiation has been successfully used in suspended slurry photoreactors. A photocatalyst (NTD) based on nanosized anatase and diatomite as a substrate has been synthesized in an electrolyser and applied for the photodecomposition of phenol in a slurry-type photoreactor.
