Simultaneous determination of dopamine, uric acid and ascorbic acid with LaFeO3 nanoparticles modified electrode

Simultaneous Determination of Ascorbic Acid, Dopamine and Uric Acid with Chitosan‐Graphene Modified Electrode

“…It is well known that at traditional bare electrodes, AA, DA and UA exhibit oxidation peaks at potentials very close to each other resulting in an overlapping voltammetric response [30]. So far, various mediators have been developed in simultaneous determination of AA, DA UA including polymers [29, 31 -33], noble metal-alloy nanoparticles [34], oxides [35,36], carbon based materials [37 -39] and composites based on the above materials [40 -43]. However, no report is available concerning the use of graphene materials or their composites as electrode modifying material for simultaneous determination of biological compounds such as AA, DA and UA so far.…”

Photocatalytic degradation of organic dyes under visible light irradiation by floral-like LaFeO3nanostructures comprised of nanosheet petals

“…The corresponding broad exothermic peak in the DTA curve at 385 1C also emphasizes the same. 9 Decomposition of oxycarbonates was complete in the temperature range 435-640 1C with a minor weight loss of 1.8%. The low intense exothermic peak observed at 560 1C is possibly attributed to the gradual crystallization of LaFeO 3 .…”

“…Several techniques have been involved in the growth of LaFeO 3 nanostructures like sol-gel, hydrolysis, thermal evaporation and chemical vapor deposition. [9][10][11][12][13][14][15][16] Among the synthetic methods available a surfactant-assisted hydrothermal route has significant advantages like low temperature growth, cost effectiveness and a less complicated process. [17][18][19] The surfactant performs the role of a template to produce unique morphology by a self-assembly process with diverse tunable properties like surface area and crystallite size.…”

Detection of Uric Acid in the Presence of Dopamine and High Concentration of Ascorbic Acid Using PDDA Modified Graphite Electrode

“…It has been observed that gold nanoparticles immobilized on amine terminated self assembled monolayer on a gold electrode [5], nanogold modified carbon fiber electrodes [16], enzyme uricase immobilized ZnO nanorods [17], magnetic nanoparticles of Fe 3 O 4 of approximately 5 nm deposited on gold electrode [18], titanate nanotubes [19], gold nanoparticle/choline composites [20], and LaFeO 3 nanoparticles [21] and more recently Pd nanoparticle [8] have been used for the determination of these species. Boron doped diamond electrode [22], Carbon ceramic electrode [23] and Carbon ionic liquid electrodes [24,25] have also been applied for selective determination of UA, DA and AA.…”
