Abstract

The countless existence of pharmaceutical pollutants discharged wastewater has been identified as a potential concern for aquatic creatures and humans. Despite the fact that their presence in drinking water has caused significant concern, little is known about their fate and environmental impact. As a result, these contaminants are inexorably pushed into our food chain even at low levels. Pharmaceutical effluents have a both direct and indirect impact on environmental and human health, especially in the vicinity of pharma industrial zones. Therefore, it is important to remove pharmaceutical pollutants from wastewater before final discharge in the environment. Among various treatment, photocatalysis has been widely regarded and gained popularity in recent years as a potential technology for removal of variety of environmental contaminants. The present mini review mainly focused on the feasibility of photocatalysis process for its potential to treat pharmaceutical wastewater. Moreover, the emphasis is given to the solar based (visible light active) photocatalyst such as C₃N₄ and its composites.
