Natural Clay-Based Materials for the Removal of Antibiotics from Contaminated Water

The release of antibiotics into the environment has increased remarkably due to the extensive use of these pharmaceuticals worldwide. Sulfamethoxazole (SMX) and trimethoprim (TMP), two antibiotics proposed in the 3rd Watch List (WL) under the Water Framework Directive (Directive 2000/60/EC) and ofte...
