“…The morphology evolution of the products is relative to the reaction time and hydrothermal temperature. [26][27][28][29][30] The diameter and length of the Li doped bismuth oxide nanorods increase obviously with the increase of the reaction time and hydrothermal temperature leading to the final formation of the Li doped bismuth oxide nanorods.…”

“…28,33,35 Figure 8 shows the electrochemical CV curves of 2 mM L-cysteine in 0.1 M KCl solution at the Li doped bismuth oxide nanorods modified GCE using the scan rate from 25 mV·s -1 to 200 mV·s -1 . As shown in the inset of upper-left part of Figure 8, the intensities of the electrochemical CV peaks are linear to the scan rate ranging from 25 mV·s -1 to 200 mV·s -1 which is similar to that reported by other groups.…”

Li doped bismuth oxide nanorods have been prepared using sodium bismuthate and Li acetate. X-ray diffraction (XRD) pattern shows that the nanorods are composed of monoclinic Bi 2 O 4 and cubic LiBi 12 O 18.50 phases. Scanning electron microscopy (SEM) observation shows that the nanorods have the length and diameter of 1-5 μm and 50-350 nm, respectively. The formation of the Li doped bismuth oxide nanorods is closely relative to the hydrothermal conditions. The electrochemical performance for the determination of L-cysteine based on a Li doped bismuth oxide nanorods modified glassy carbon electrode (GCE) has been developed. The CV peak current increases obviously and linearly with increasing the scan rate. Under the optimal conditions, Li doped bismuth oxide nanorods modified GCE exhibits good analytical performance with good reproducibility and stability. The linear range of L-cysteine is 0.0001-2 mM and the detection limit is 0.36 μM and 0.17 μM for cvp1 and cvp2, respectively.

“…The detection of organic acids is an interesting and challenging issue in analytical biochemistry because organic acids are widely present in food, body fluids, beverages and environmental liquids (Yang et al, 2000;Pei et al, 2015aPei et al, , 2015b. In present organic acids, tartaric acid belongs to important organic biomolecules which is widely used in the fields of food, pharmacology and chemistry industry (Kvaratskhelia and Kvaratskhelia, 2008;Guth et al, 2009].…”

“…Cu vanadate one-dimensional (1D) nanomaterials, such as nanorods and nanobelts exhibit great application potential in electrochemical sensors and lithium ion batteries owing to good electrochemical properties and high discharge capacity (Li et al, 2009;Ma et al, 2008;Pei et al, 2015aPei et al, , 2015b. In our previous research, Cu vanadate nanorods were synthesised by a simple hydrothermal process (Lin et al, 2015).…”

Cu vanadate nanorods have been used as the glassy carbon electrode (GCE) modified materials for the electrochemical detection of tartaric acid. The effects of scan rate, tartaric acid concentration and electrolytes in the electrochemical behaviours of tartaric acid in KCl solution have been analysed. Two pairs of semi-reversible cyclic voltammogram (CV) peaks are observed. The CV peaks are located at +0.12 V, -0.04 V (cvp1, cvp2) and -0.07 V, -0.41 V (cvp1′, cvp2′), respectively. The intensity of the electrochemical CV peaks increases linearly with the increase of the scan rate from 25 to 200 mVs -1 , tartaric acid concentration from 0.01 to 2 mM, respectively. The detection limit is 7.6 μM and 1.3 μM for cvp1 and cvp2, respectively at a signal-to-noise ratio of 3. Cu vanadate nanorods modified GCE shows good stability.Keywords: tartaric acid; Cu vanadate nanorods; electrochemical detection; glassy carbon electrode; GCE.Reference to this paper should be made as follows: Pei, L.Z., Wei, T., Lin, N.

“…The quantitative detection of AA is obviously important. Common analysis methods for AA detection include fluorescent spectrophotometry, 1,2 electrochemistry, 3 chromatogram, 4 colorimetric analysis. [5][6][7][8][9] Some of these techniques require complicated sample preparation or sophisticated instrumentation, but the colorimetric method has great potential for AA detection owing to its simple, rapid operation and cost-effectiveness.…”

Au nanoparticles (AuNPs) dispersed in water were stabilized by tripolyphosphate (P3O10 5-). When Cr2O7 2-(Cr(VI)) was present, the AuNPs did not change; when Cr 3+ (Cr(III)) was present, the AuNPs would aggregate because of cooperative metal-ligand reaction. Aggregated AuNPs showed different color from the non-aggregated ones. Thus, a simple colorimetric assay was made using AuNPs-Cr(VI) to detect ascorbic acid (AA). Upon introducing AA to the AuNPsCr(VI) system, Cr(VI) was reduced to Cr(III), and the aggregation of AuNPs occurred. This colorimetric assay performed high selectivity and a linear concentration response in the range of 0.2 to 10 μM; its limit of detection was 0.15 μM.
