“…The Attenuated Total Reflectance Fourier Transform infrared (ATR‐FTIR) spectra of graphite and graphene oxide are shown in Figure S1. It can be seen that a characteristic peaks of graphene oxide are O–H stretching vibration at 3208 cm −1 , C=O stretching vibration at 1717 cm −1 and the remaining sp 2 stretching vibration at 1617 cm −1 .…”

The proposed chemically modified electrode was graphene oxide that was synthesized via Hummer's method followed by reduction of antimony film by in‐situ electrodeposition. The experimental process could be concluded in three main steps: preparation of antimony film, reduction of analyte ions on the electrode surface and stripping step under the conditions of square wave anodic stripping voltammetry (SWASV). A simple and rapid approach was developed for the determination of heavy metals simultaneously based on a sequential injection (SI), an automated flow‐based system, coupled with voltammetric method using antimony‐graphene oxide modified screen‐printed carbon electrode (SbF‐GO‐SPCE). The effects of main parameters involved with graphene oxide, antimony and measurement parameters were also investigated. Using SI‐SWASV under the optimal conditions, the proposed electrode platform has exhibited linear range from 0.1 to 1.5 M. Calculated limits of detection were 0.054, 0.026, 0.060, and 0.066 μM for Cd(II), Pb(II), Cu(II) and Hg(II), respectively. In addition, the optimized method has been successfully applied to determine heavy metals in real water samples with acceptable accuracy of 94.29 – 113.42 % recovery.

“…The limits of detection of the analytes are superior than or comparable to those acquired with other reported methods [15,[20][21][22][23][24]. Although some of these methods have better detection limits or higher preconcentration factors, they need large sample volumes [15,16,18,19,21,22]. This often adds significantly to the time required for analysis and is clearly more problematic during the collection and transport of the samples.…”

In the present study, a new solid phase extraction method was developed for simultaneous preconcentration of copper(II) and iron(III) ions from natural waters. The analytes were first complexed with 4aminoantipyrine at pH 8.0 and then passed through the column packed with C18-silica. The retained analytes on the C18-silica were eluted with 1.0 mL of 0.5 M nitric acid in 10% ethanol and determined using flame atomic absorption spectrometer. The influence of several variables such as sample pH, ligand amount, eluent type, sample and eluent flow rates, and sample volume on the retention/or elution of the analytes were examined and optimized. The effects of some interfering ions on the retentions of analytes on C18-silica were also enquired. The detection limits were 0.89 µg/L for Cu and 1.41 µg/L for Fe with a preconcentration factor of 20. The calibration graphs were linear in the concentration range of 5.0-125 µg/L of the analytes. The calibration equations were A=2.36x10 -3 C + 4.55x10 -4 for Cu and A=1.45x10 -3 C + 8.88x10 -4 for Fe. The accuracy of the proposed method was verified by the analysis of SPS-SW2 Batch 127 certified reference water. The method was applied to river water and seawater samples with recoveries in the range of 95-99%.

“…The traditional methods for detecting these metal cations include atomic absorption spectrometry, voltammetry, and laser-induced breakdown spectroscopy. [68,69,70] However, these detection technologies all have the common characteristics that the equipment is expensive, operational cost high, and operation complex. Fluorescence chemical sensors have the advantages of high sensitivity, visualization, and simplicity in detecting trace metal ions.…”

Recent materials research based on fluorescent nanocelluloses (NCs) used in the field of sensing and bioimaging is reviewed. Many designed morphologies have been reported, such as nanoparticles, fibers, nanopapers, hydrogels and aerogels, that have been produced by physical or chemical methods. In the field of sensing and bioimaging, these studies have involved, but not been limited to, special optical properties including fluorescence, long‐lived luminescence, polarized light, and/or aggregation‐induced emission. The fluorescence sensing platforms can be categorized according to stimuli such as pH and temperature, as well as the presence of toxic compounds, and anions and metal cations. In addition, NCs exhibit unique low toxicity, good biocompatibility, biodegradability and cell membrane penetration, and can be modified into fluorescent nanoprobes for in vivo imaging and tracing. As an excellent platform for fluorescent sensing and bioimaging, NCs are bound to be increasingly studied and widely applied in the field of production and life sciences.
