Fabrication of Anchored Complexes as Electrodes for Sensing Heavy Metal Ions by Electrochemical Method

Abstract

Anchored coordination complexes as electrochemical sensors play a significant role in the modern era. It is evident that this becomes a fact on account of their practical convenience. Furthermore, they have unlimited scope in ecological, therapeutic, experimental and biomedical applications. It has been observed that 165 such papers have reported on anchored complexes for electrochemical sensing during the past two years. While human vitality is rigorously threatened by heavy metal ions today, numerous trials are restrained for screening these in nature. This retrace highlights the electro analytical methods and the masterpiece contribution of anchored coordination complexes as electrochemical sensors for the identification of heavy metals such as indium, uranium, lead, beryllium, and mercury in 2015 and 2016.

Beryllium ion sensing through the ion pair formation between the electrochemically reduced ferrocenyl naphthoquinone radicals and $$\hbox {Be}^{2+}$$ ions

“…15 In the present work, a simple and sensitive electrochemical method was developed for the determination of Be 2+ using SWV through the ion pair formation between the electrochemically reduced monoanion radical products (Fc-cnq-1a • − /Fc-cnq-1b • − ) and Be 2+ . In the past studies, although trace amount of Be 2+ was determined by using adsorptive stripping voltammetry and adsorption voltammetry based on the polymericelectrosensor, 15,[35][36][37] the ion-pair formation process is facilitated for the first time to determine ultra-trace amount of Be 2+ in our study.…”
