Analytica Chimica Acta journal has published an article written by researchers of Tehran'sSharif University of Technology titled "A chitosan-polypyrrole magnetic nanocomposite as -sorbent for isolation of naproxen".

It is a prestigious scientific journal published by Elsevier since 1947 and covers original research and reviews of fundamental and applied aspects of analytical chemistry, ISNA reported.

Habib Baqeri, professor of analytical chemistry, and Ali Roustaei, PhD student from Sharif University of Technology, were authors of the article.

Naproxen is a non-steroidal anti-inflammatory drug commonly used for relief of a wide variety of pain, fever, inflammations and stiffness.

The drug enters through surface waters from sewage and wastewaters, and poses a pollution risk to environment. Therefore, it is important to measure the concentrations of naproxen in water and remove it.

In the study, an extracting medium based on chitosan-polypyrrole (CS-PPy) magnetic nanocomposite was synthesized by chemical polymerization of pyrrole in the presence of chitosan magnetic nanoparticles (CS-MNPs) for micro-solid phase extraction.

Extraction efficiency of the nanocomposite was compared with the CS-MNPs and Fe3O4 nanoparticles for the determination of naproxen in aqueous samples.

The scanning electron microscopy images revealed that the CS-PPy nanocomposite possesses more porous structure.

Among different synthesized nanocomposites, CS-PPy magnetic nanocomposite showed greater efficiency
