Light-Activated Catalyst for Treating Highly Toxic Water Pollutants

Technology Overview

This novel and environment-friendly modified titanium oxide (TiO2) photocatalyst enables the degradation of 4-chlorophenol through visible light. According to the United States Environmental Protection Agency, 4-chlorophenol is a primary water pollutant owing to its potential as a carcinogen to mammals and aquatic life. This pollutant typically comes from the production of chemical feedstocks associated with the manufacture of fungicides, antiseptics, disinfectants and dyes, among others. The laboratory test recorded an initial pollutant concentration of 10 parts per million (ppm) under visible light with an irradiation period of three (3) hours. The photocatalyst can be reused up to three (3) times with minimal decrease in removal efficiency.

Technology Features & Specifications

This visible light-activated photocatalyst is capable of removing highly toxic substances, persistent organic pollutants and dyes from water.The increase in demand for agrochemical products and prevalence of health problems associated with the use of contaminated water createan urgent need for this technology. Key Features: High removal efficiency About 25% faster than other photocatalysts Reusable of up to at least three (3) times Lab-validated using synthetic wastewater

Potential Applications

Alternatives for photocatalytic wastewater treatment include biological treatment, which often takes a long time to mineralize pollutants; chlorination, which results in carcinogenic by-products; and granulated activated carbon and absorption, which bring about problems with disposal of the carbon used. The use of these methods is inefficient compared to the benefits offered by this technology. The technology can also be used to help eliminate pathogens andharmful bacteriaand viruses in contaminated water,showingits significant potential in industrial wastewater treatment as well as environmental management and sustainability.
