Potentiometric sensors constructed with [bmim]BF4 and MWCNTs show better sensitivity, selectivity, response time, and response stability compared to Er III) carbon paste sensors.
Carbon paste sensors were constructed by mixing the molecularly imprinted, ordered mesoporous silica with graphite powder and paraffin oil, and they were found to detect bisphenol A (BPA) with enhanced selectivity due to their ordered mesoporous structure and their successful molecular imprinting.
NSP was used as a sensing material during construction of carbon paste Er III) sensors.
The most reliable design is that of carbon paste based sensors; this design was adopted for the construction of potentiometric, enantioselective membrane electrodes as well as for the construction of the amperometric biosensors, and immunosensors.
Tartrazine dye Na3TZ in foodstuff products was determined by a new modified carbon paste electrode, encoded sensor A, and a coated silver wire electrode, encoded sensor B, based on tartrazine TZ- cetryltrimethyl ammoniumbromide CTAB as a chemical modifier TZ-CTA.
The MIP was synthesized by using PP as template and methacrylic acid as functional monomer and then incorporated in the carbon paste electrode as PP sensor.
In the presence study we describe synthesis and application of new nanocomposite (ZnO/CNTs) room temperature ionic liquid (RTIL) modified carbon paste electrode as a voltammetric sensor for determination of noradrenaline (NE) in pharmaceutical and biological samples.
Thus, modified carbon paste electrodes (MCPEs) and related sensors using different types of modifiers (chemicals, enzymes, and extracts) have been developed (Chow and Gooding [2006]; Heitzmann et al. [2005]; Ensafi et al. [2010]; Portaccio et al. [2010]).
We intend to use the fabricated ractopamine-tetraphenylborate complexed nanoparticles (RT NPs) as modifiers to form an electrochemical sensor with a carbon paste electrode and apply it to determine ractopamine in pork samples conveniently and rapidly.
This latter OP-MMT intercalate was used as Pb II) sensor via a carbon paste electrode (CPE) by adsorptive stripping voltammetry because it should lead to the exchange of hydrated sodium ions by Pb II).
