“…It is obvious from Figure 5 that there were differences between peak potentials of different concentrations of cadmium. This phenomenon is also presented in papers of other authors dealing with modification of glassy carbon electrode with different ferrites 20, 21. There are two theories about this phenomenon.…”

“…In recent years, anodic stripping voltammetry (ASV) has played an increasing role in the determination of heavy metal ions because of high sensitivity, short analysis time and inexpensive equipment. Anodic stripping voltammetry has been established as a powerful tool for the determination of trace metal ions, owning to an effective preconcentration step with advanced electrochemical measurements of the accumulated ions 16–21. Mercury is often the best electrode material for the trace analysis of metals.…”

This paper describes the preparation of a new sensor based on Zn‐ferrite modified glassy carbon paste electrode and its electrochemical application for the determination of trace Cd(II) ions in waste waters using differential pulse anodic stripping voltammetry (DPASV). Different Zn/Ni ferrite nanoparticles were synthesized and characterized using scanning electron microscopy (SEM) and X‐ray powder diffraction (XRPD). The prepared ferrite nanoparticles were used for the preparation of Zn‐ferrite‐modified glassy carbon paste electrode (ZnMGCPE) for determination of Cd(II) at nanomolar levels in waste water at pH 5. The different parameters such as conditions of preparation, Zn2+/Ni2+/Fe2+ ratio and electrochemical parameters, percentage of modifier, accumulation time, pH and accumulation potential were investigated. Besides, interference measurements were also evaluated under optimized parameters. The best voltammetric response was observed for ZnFe2O4 modifier, when the percentage of modifier was 3 %, accumulation time 9 min, pH of supporting electrolyte 5 and accumulation potential −1.05 V. Thus prepared electrode displays excellent response to Cd(II) with a detection limit of 0.38 ppb, and selective detection toward Cd(II) was achieved.

“…SMEs coupled stripping methods is a highly comprehensive approach for addressing shortcomings with current methodologies for trace analysis . The most common practice utilized is the enhancement of selectivity towards host and target . Based on the principle, electrode modification by a series of reagents including amoxicillin , hexacyanoferrate , tetraethylthiuram disulfide , tetraphenylporphyrin , p‐tert‐butylcalix(4)arene , organofunctionalized silica and nafion have been reported for copper determination.…”

This study reports a highly sensitive electrochemical sensor based on Bi film modified glassy carbon electrode (BiF/GCE) for total determination and speciation trace concentrations of copper(II) ions in environmental water samples. Square wave‐adsorptive anodic stripping voltammetric (SW‐ASV) experiment was performed for monitoring selective accumulation of copper(II) with reagent 3‐[(2‐mercapto‐vinyl)‐hydrazono]‐1,3‐dihydro‐indol‐2‐one (MHDI) at pH 9–10. The mechanism of the electrode reaction of Cu2+‐MHDI complex was safely assigned. The sensor exhibited a wide linear range (3.22×10−9–2.0×10−7 mol L−1) with lower limits of detection (LOD) and quantitation (LOQ) of 9.6×1−10 and 3.22×10−9 mol L−1, respectively (R2=0.9993). The proposed sensor exhibited interference from active metal ions e. g. Cd, Hg. The performance of the proposed method was compared successfully with most of the reported methods and comparable efficiencies were obtained. The analytical utility of the proposed SW‐ASV method has been successfully validated for trace analysis of copper(II) in environmental water samples. The method offers a precise, accurate approach with good reproducibility, robustness, ruggedness, and cost effectiveness.

An Organic Transistor-based Electrical Assay for Copper(II) in Water

et al. 2017

View full text Add to dashboard Cite

We herein report an electrical assay for copper(II) (Cu 2+ ) utilizing an organic thin-film transistor (TFT). To endow the metal ion recognition ability, the extended-gate portion in the organic TF T is functionalized by a nitrilotriacetic acid (NTA)-terminated monolayer. As a result, the device responds selectively to Cu 2+ in aqueous media. Importantly, the estimated detection limit for Cu 2+ (= 96 ppb) is much lower than environmental standard value of a copper contaminant in drinking water. Its superior processability and portability in the organic device indicate that the proposed assay could be applied for on-site detection of the Cu 2+ ion without large-sized equipment.
