Summary
A novel CNT@NiFe2O4 nanocomposite effectively removes phenobarbital (PHEN) from water. This magnetic material shows promise for treating aquatic pollution from pharmaceutical contaminants.
Area of Science:
- Environmental Science
- Materials Science
- Nanotechnology
Background:
- Pharmaceuticals like phenobarbital (PHEN) are emerging aquatic pollutants.
- Industrial, hospital, and domestic effluents pose global health risks.
