Simultaneous voltammetric detection of ammonium and nitrite from groundwater at silver-electrodecorated carbon nanotube electrode

Methods for the Detection and Remediation of Ammonia from Aquaculture Effluent: A Review

“…A potential is developed by the membrane as the electrode is placed in an aqueous medium and thus selectively detect ammonium [58]. The last two decades have witnessed a paradigm shift towards the use of nanomaterials-modified electrodes due to their unique, tailorable electrical properties, large surface area to volume ratio, improved sensitivity, specificity and selectivity for the determination of analytes [59]. In nanomaterialmodified electrodes, modifications can be imparted through the designation of nano-functional materials with specific chemical properties on the electrode surface.…”

“…CNTs possess a high surface area and their composites could serve as suitable templates for advanced sensor design. Baciu et al [59] utilized silver-modified CNT (Ag-CNT) for electrochemical sensing of ammonium and nitrite ions in aqueous solution. Zhang et al [60] carried out electrode position of platinum nanoparticles on the surface of Ag/PPy-polypyrrole-Ni foam for the sensitive and selective detection of ammonia (LOD value of 37 nM).The result showed a significant left shift by the oxidation potential.…”

Poly(Taurine‐Glutathione)/Carbon Nanotube Modified Glassy Carbon Electrode as a New Levofloxacin Sensor

“…The conventional electrodes have poor performance to analytes due to the easy deterioration of electrode surface by the analyte and related intermediates, thus many researchers prefer to study with the modified electrodes . Among various kinds of modifiers, carbon nanotubes (CNTs) have attracted tremendous interest since it possess high surface‐to‐volume ratio, excellent conductivity, chemical stability and also have ability to be easily functionalized and modified to surfaces . All of these features make CNTs one of the most‐preferred in the modification of the electrodes.…”

Electrochemical sensing mechanism of ammonium ions over an Ag/TiO2 composite electrode modified by hematite

“…to reduce costs, control the morphology, increase the number of active sites, or enhance mass transfer, thereby improving the sensing performance and stability. [8][9][10][11][12] Among them, Ag-based electrochemical sensors are attractive candidates due to their strong affinity for ammonia. For example, an electrochemical ammonia sensor based on Ni foamsupported Ag/polypyrrole composites provides a high sensitivity of 0.089 mA mM À1 , a wide linear range from 100 nM to 100 mM, and good anti-interference.…”
