“…For example, lead has obvious effects on renal, brain development and blood pressure [ 3 ], and cadmium is primarily toxic to the kidney, especially to the proximal tubular cells [ 4 ]. Therefore, it is of significance to develop sensitive, rapid and simple analytical methods for the detection of trace amounts of Pb 2+ and Cd 2+ ions [ 5 , 6 ]. The common methods for heavy metals analysis include atomic absorption spectrometry (AAS) [ 7 ], atomic emission spectrometry (AES) [ 8 ], atomic fluorescence spectrometry [ 9 ] and inductively-coupled plasma mass spectrometry (ICP-MS) [ 10 ].…”

The fabrication and evaluation of a glassy carbon electrode (GCE) modified with self-doped polyaniline nanofibers (SPAN)/mesoporous carbon nitride (MCN) and bismuth for simultaneous determination of trace Cd2+ and Pb2+ by square wave anodic stripping voltammetry (SWASV) are presented here. The morphology properties of SPAN and MCN were characterized by transmission electron microscopy (TEM), and the electrochemical properties of the fabricated electrode were characterized by cyclic voltammetry (CV). Experimental parameters, such as deposition time, pulse potential, step potential, bismuth concentration and NaCl concentration, were optimized. Under the optimum conditions, the fabricated electrode exhibited linear calibration curves ranging from 5 to 80 nM for Cd2+ and Pb2+. The limits of detection (LOD) were 0.7 nM for Cd2+ and 0.2 nM for Pb2+ (S/N = 3). Additionally, the repeatability, reproducibility, anti-interference ability and application were also investigated, and the proposed electrode exhibited excellent performance. The proposed method could be extended for other heavy metal determination.

“…Pristine CNTs are often pretreated by exposure to acids such as HNO 3 , H 2 SO 4 , HCl or a mixture of them to eliminate amorphous carbon and metal catalyst impurities and to introduce carboxyl and carboxylate groups at defects and the end of the CNTs surface. Functionalization by carboxylic groups can improve the conductivity of the electrode and cause electrostatic interaction between the CNTs electrode and target cations that improve the electrochemical signal . Functionalization with amino groups (−NH 2 ) and thiol groups (−SH) has also been used to preconcentrate metals on the electrode surface by coordination through the interaction between electron‐rich ligands and electron‐deficient heavy metal ions .…”

The challenge of heavy metal detection for environmental, industrial and medical purposes has led to the development of many analytical techniques. Stripping voltammetry is a very sensitive electrochemical method and has been widely used for heavy metal detection. Carbon nanotubes, a well-studied carbon material with physical and chemical properties suited for electrode material is commonly employed for sensitive and selective metal detection in electrochemistry. This article reviews the recent (2011-2016) applications of carbon nanotubes as an electrode or electrode surface modifier for heavy metals detection with stripping voltammetry.

“…The setting up of various materials has widened the electrochemical achievements. For concrete illustration, polymers or biomaterials are regularly come together on inorganic nanomaterials to manufacture the highly responsive electrochemical sensors for heavy metal ions [9][10][11][12][13][14][15][16][17][18] .Because of the potential for the small analytical period, less engine capacity, valuable sensitivity and simple adaptability for in-situ extent 19 ,electrochemical detection methods using anchored complexes have attracted enormous attention in the detection of heavy metal ions. This review summons up the formulation and sensing means such as the molecularly imprinted polymers, ion-imprinted polymers, exploitation incentive responses of a deoxyribozyme (DNAzyme), fluorescence and complexes with conducting nation binders for heavy metal ions in 2015 and 2016are briefly explained.…”

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.
