Removal of aspirin and paracetamol from aqueous solution by using tea waste modified PEI adsorbent

The water bodies were determined to have been polluted by high concentration of pharmaceutical substances such as aspirin and paracetamol which may harm the ecosystem and bring health hazard to human. Conventional water treatment such as activated carbon used to remove these substances were not cost...
