Abstract
Environmental pollution has become a serious problem at a global level because of its widespread and long-term harm. Contamination by heavy metal ions and toxic heavy metals, including zinc, copper, nickel, mercury, cadmium, and lead, causes significant long-term damage to many biological systems because these metals disrupt biological activities at the cellular level. Lead is one of the most abundant metals on earth. However, lead poisoning has been related to several diseases associated with environmental pollution. Therefore, it is essential to detect and remove lead ions from aqueous solutions. Water-soluble and stable cethyltrimetylammonium bromide (CTAB)-capped gold nanoparticles (AuNPs) were applied for the sensitive detection of Pb2+. These CTAB-capped AuNPs were employed to selectively detoxify heavy-metal ions such as Pb2+ ions. Detailed studies using UV/visible spectroscopy, electron microscopy, and dynamic light scattering showed that competitive binding of Pb2+ with the CTAB-capped AuNPs changed the surface properties in the presence of sodium thiosulfate (S2O 2-3 ). This system is able to detect Pb2+ with a detection limit as low as 20 nM. This method has a great potential for the simple and rapid detection of lead ions with ultrasensitive and excellent selectivity.
