“…Rahman et al reported TiO 2 films and SrO‐CNT composite based hydrazine sensor wherein ethanolic nafion solution was used as conducting coating binder with active material during electrode fabrication. The current work is advantageous as it reports a high yield, green synthesis approach of CQD using a benign precursor, chia seeds where, the as‐prepared products were self‐passivated providing the CQD with excellent solubility thus avoiding the need for a separate step for passivation.…”

“…Therefore, a reliable technique for the detection of hydrazine (4nitrophenylhydrazine) is necessary. In recent, many kinds of research have been conducted based on CoS2-CNT nanocomposites [26], SrO.CNT NCs [27], Fe2O3 NPs [28], Co-doped ZSM-5 zeolites [25], TiO2 nanoparticles [32], Fe2O3/CeO2 nanocubes [33] and ZnO nano-urchins [29] coated on GCE for precious hydrazines detection ( both aromatic and aliphatic) applying electrochemical (I-V) approach. This experimental work performed to assemble a sensor in I-V approach selective to 4-NPHyd with ZnO/SnO2 NPs coated on GCE.…”

The 4-NPHyd (4-nitrophenylhydrazine) electrochemical sensor assembled using wet-chemically prepared ZnO/SnO2 nanoparticle (NPs) decorated a glassy carbon electrode (GCE) with conductive Nafion binder. The synthesized NPs characterized by XPS, ESEM, EDS, and XRD analysis. The calibration of the proposed sensor obtained from current versus concentration of 4-NPHyd found linear over a concentration (0.1nM~0.01mM) of 4-NPHyd, which denoted as the dynamic range (LDR) for detection of 4-NPHyd. The 4-NPHyd sensor sensitivity calculated using the LDR slope considering the active surface of GCE (0.0316 cm2), which is equal to be 7.6930 µAµM-1cm-2, an appreciable value. The detection limit (LOD) at signal/noise (S/N=3) estimated, and outstanding lower value at 94.63±4.73 pM perceived. The analytical parameters such as reproducibility, long-term performing ability and response time are found as appreciable. Finally, the projected sensor shows exceptional performances in the detection of 4-NPHyd in environmental samples.

We report the synthesis of a novel nanocomposites based Poly (pyrrole-co-o-toluidine) copolymer and cobalt ferrite (CoFe 2 O 4 ) as an electrochemical sensor for selective Pb 2 + detection. The general abbreviation of these new materials are given as P(Pyco-OT)/CF nanocomposites (P(Py-co-OT)/CF NCs). The synthesis was performed via in situ-chemical oxidative polymerization method at different CoFe 2 O 4 weight ratio (5%, 10%, 30%, 50% and 70%), whereas CoFe 2 O 4 nanoparticle (NPs) was synthesized by an egg white method prior the nanocomposite formation. The structural, morphological, thermal, magnetic, electrical and electrochemical properties of pure P(Py-co-OT), CoFe 2 O 4 and P (Py-co-OT)/CF NCs were characterized by XRD, FTIR, TGA-DTG, SEM-EDX, TEM, VSM and electrical conductivity. The results of XRD and FTIR confirmed the formation of P(Py-co-OT)/CF NCs with the component CoFe 2 O 4 showing spinel structure. The analysis of TGA-DTG presented that CoFe 2 O 4 NPs improved the thermal stability of NCs indicated the presence of some interactions between the interface of P(Py-co-OT) and CoFe 2 O 4NPs, which affects the chemical and physical properties of the NCs. The ac conductivity was also examined as a function of temperature. The measures showed a decrease in the conductivity of NCs when increasing the insulating CoFe 2 O 4 NPs contents. A cost-effective and reliable electrochemical sensor selective to Pb 2 + ion was fabricated using P(Py-co-OT)/CF NCs on glassy carbon (GCE). It was found that the P(Py-co-OT)/CF 10 NCs exhibit excellent detection of Pb 2 + ion. The proposed Pb 2 + ion sensor was performed linearly over the large concentration range of 0.1 nM ∼ 0.01 mM labelled as linear dynamic range (LDR). The sensitivity as well as detection limit were estimated to be 22.39 μAμM À 1 cm À 2 and 42.39 � 2.12 pM, respectively. The desired ionic sensor-based on P(Py-co-OT)/CF 10 NCs/binder/GCE was found as efficient to detect Pb 2 + ion in environmental and biological samples significantly. The analytical sensor performances such as reproducibility, sensitivity, stability, validation, and response time were reliable and significant.
