The removal of toxic metal ions and accessibility of clean water remain a critical challenge to mankind in the current scenario, expected to increase in the near future. This has necessitated the need for effective removal of toxic metal ions. The most critical problem encountered in adsorbents including nanofibers is their limited adsorption capacity due to the adsorption of metal ions on their surface as monolayers and denaturation of adsorbents.<\/p>\n<p>Dr Anitha Senthamizhanm, Dr Brabu Balusamy and Dr Asli Celebioglu presented a research work highlights the preliminary efforts to devise a synthetic strategy for the effective removal of Pb<sup>2+<\/sup>\u00a0in water by creating stable \u201cnanotraps\u201d in electrospun porous cellulose acetate fibers (pCAFs) under the supervision of Assoc. Prof Tamer Uyar. And also the authours paid more attention to study the interaction between fibrous mat and water and their transport behavior to improve the overall removal capacity of metal ions. Interestingly, it has been found that the occurrence of pores greatly enhances the capillary effect of the pCAFM\/AuNC when compared to the nonporous fibrous membrane. As a result, the pCAFM\/AuNC has the ability to remove the metal ions in the order of Pb<sup>2+<\/sup>\u00a0&gt; Zn<sup>2+<\/sup>\u00a0&gt; Cd<sup>2+<\/sup>\u00a0&gt; Hg<sup>2+<\/sup>\u00a0&gt; Ni<sup>2+<\/sup>\u00a0&gt; Mn<sup>2+<\/sup>. The results showed a higher degree of removal efficiency towards Pb<sup>2+<\/sup>\u00a0when compared to other metal ions. The resulting outcome suggests the removal of \u223c70% of Pb<sup>2+<\/sup>\u00a0within 5 minutes, and the removal efficiency gradually increases and reached 99% within 3 h. The study described here opens up a new path towards preparing a stable composite membrane containing vast nanotraps without comprising or losing the parent properties of the adsorbent.<\/p>\n<p>The complete study has been published as an Inside Front Cover in J.
