Degradation of Anti-Inflammatory Drugs in Synthetic Wastewater by Solar Photocatalysis
Due to the high number of anti-inflammatory drugs (AIMDs) used by the public health sector in Iraq and distributed all over the country and due to their toxicity, there is a need for an environmental-friendly technique to degrade any wasted (AIMD) present in aquatic ecosystem. The degradation of dic...
