PEG as versatile mediating agent for sensing heavy metal ions: A mini review

Abstract

The increasing presence of heavy metal ions in aquatic environments has become a subject of escalating concern in contemporary times. Numerous human-induced activities have contributed to an elevated presence of heavy metal ions in aquatic environments, surpassing the threshold levels established by the World Health Organisation (WHO). Recently, there has been a significant increase in the utilisation of polyethylene glycol (PEG) due to its exceptional characteristics in addressing the pressing issue of aquatic pollution resulting from the presence of heavy metal ions. This mini review evaluates the detection activities in which PEG plays a significant role. The detection strategy utilising PEG composites is thoroughly described, beginning with an examination of the inherent properties of PEG. Furthermore, it concludes with suggestions for future research in this area.

Glutathione as a novel engineered biomaterial for heavy metal ion quantification and remediation

“…Meanwhile, the binding affinity of glutathione to heavy metal ions makes it effective in sequestering and removing these pollutants. Consequently, glutathione has been widely used for heavy metal remediation from contaminated water or soil [5,6] .…”
