Fabrication of carbon nanotube and synthesized Octadentate ligand modified electrode for determination of Hg (II) in Sea water and Lake water using square wave anodic stripping voltammetry

New Generation of Electrochemical Sensor for Sub-Nanomolar Zn (II) Ion Detection Based on Nano- Sized Ion Imprinted Polymer and Functionalized Multi-Walled Carbon Nanaotube Composite Modified Glassy Carbon Electrode

“…The signi cant difference between the two CVs indicates the successful dispersion of MWCNTs into the IIP bulk. This results demonstrate that the successful dispersion of MWCNTs into the IIP opens an e cient path for ET between Fe(CN) 6 3−/4− redox couple and GCE by enhancing charge transfer kinetics [41].…”

Electrochemical sensing of Hg(ii) in chicken liver and snail shell extract samples using novel modified SDA/MWCNT electrodes

“…A paraffin wax-impregnated graphite electrode (PGE) was prepared following the procedure reported in the literature. 42 An SDA/MWCNT-modified electrode was prepared: initially, MWCNTs (0.1 mg) were dispersed in 1 mL of ethanol by ultrasonication, for 45 min, and then 10 μL of dispersed solution of multiwalled carbon nanotubes (MWCNTs) was coated onto the polished PGE. Then, 1 mM synthesised SDA ligand (10 μL) added into an acetonitrile solution was mantled onto the modified MWCNT electrode and then allowed to dry under ambient conditions, and an SDA/MWCNT-modified electrode was obtained.…”

Hg2+ determination by DPASV by using poly (methylene disulfide)/Au nanoparticle/MWCNT modified glassy carbon electrode by differential pulse anodic stripping voltammetry (DPASV) technique

“…In this way, environmental protection agency (EPA) recommended electrochemical methods for determining the concentration of mercury in different environments as practical appealing methods. Advantages of these methods are their high sensitivity, low cost, simple operation, and portability [23,[28][29][30][31][32].…”

“…Carbon-based electrodes can be considered as one of the most important voltammetric sensors due to their high mechanical and chemical stability towards harsh conditions. On the other hand, these materials can be easily modified with metal nanoparticles and polymeric nanocomposites [23,29,30,[33][34][35][36][37][38][39][40][41][42][43][44][45][46] to decrease their over potential values.…”

“…Carbon nanotubes are used as conductive material in several analytical applications because of their conductivity, high aspect ratio, and chemical-mechanical stability. These materials were used in voltammetric sensors due to their excellent electro-catalytic activity [23,29,37,40,42,43].…”
