Extraction Of Acetaminophen From Aqueous Solution By Emulsion Liquid Membrane

In recent years there is an increasing awareness of pharmaceutical contaminants in the environment. Pharmaceutical contamination in rivers is widespread with hundreds of drugs found at low concentrations. One of the main abundantly used pharmaceuticals are acetaminophen (ACTP). The application of co...
