Thiol-functionalized multi-walled carbon nanotubes for effective removal of Pb(II) from aqueous solutions

In this study, thiol-functionalized multi-walled carbon nanotubes (MWCNT-SH) was synthesised using carboxy-functionalized multi-walled carbon nanotubes (MWCNT-COOH) as a precursor and 2-mercaptoethanol as a sulfur source. It was an effective adsorbent for Pb(II) removal. The SEM, TEM, FTIR, XPS, EDS...
