Differential pulse voltammetric determination of paracetamol in tablet and urine samples at a micro-crystalline natural graphite–polystyrene composite film modified electrode

A carbon needle microelectrode decorated with TiO 2 nanosheets dominated by reactive facets as a highly electrocatalytic sensing element

“…In this case, the slope value of À 56.0 mV pH À 1 closely approximates the theoretical value of À 59.0 mV pH À 1 from the Nernst equation, indicating that equal amounts of proton and electron transfer occur in the electrode reactions. This result agrees well with those obtained at multiwalled carbon nanotubes (MWCNTs) [52], graphite/polystyrene [53], and Nafion/TiO 2 -graphene [54] modified electrodes.…”

Electrochemical preparation of nickel and copper oxides-decorated graphene composite for simultaneous determination of dopamine, acetaminophen and tryptophan

“…Acetaminophen (AC), as an anti-pyretic agent, is widely used all over the world for relieving pain and fever [23,24]. Although there is some evidence showing no propensity to be addictive by ingesting AC, overdose of AC will lead to toxic metabolite accumulation which may induce morbidity and mortality in humans [25,26].…”

Au nanoparticles/poly(caffeic acid) composite modified glassy carbon electrode for voltammetric determination of acetaminophen

“…The detection limit was calculated to be 14 nM by the equation 3σ/b, where σ is the standard deviation of the blank and b is the slope of the calibration plot [34]. A comparison between the analytical performance of the present method and some previous literature methods for the determination of AP are given in Table 1 [35][36][37][38][39][40][41][42][43][44][45]. As can be seen from Table1, the proposed method showed wide linear ranges and low detection limit for determination of AP.…”
