“…According to the literature, Multi-walled carbon nanotubes (MWCNTs) have shown an ability to efficiently remove various organic pollutants such as dioxins, polychlorinated dibenzo-furans and biphenyls from aqueous environments 5,6 . Nowadays, considerable efforts have been made to produce metal-carbon nanocomposite materials, not only because the carbonic compound improves the mechanical properties of the composites, but also because the produced composites possess the properties of individual components with a synergistic effect 7,8 .…”

This study focuses on preparing Antimony Nanoparticle Multi-walled Carbon (ANMWC) composite as an effective adsorbent and then the effect of produced composite in BPA removal from aqueous solutions was studied. ANMWC were prepared using chemical method and characterized with X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR) and Brunauer-EmmettTeller (BET). Moreover, the removal efficiency of prepared AMWCNT and Nanoparticle Multi-walled Carbon (MWCNT) in removal of Bisphenol A was investigated. Results revealed that the BPA removal efficiency by AMWCNT increased from 80 to 93 % with the increase of contact time 5 to 60 min. The maximum removal efficiency for the both adsorbents was seen at pH 7, which was 85% for MWCNT and 95% for ANMWC composite. According to the results obtained, pH zpc for both adsorbents was 7. Results showed that the adsorption process followed the pseudo-first order model with a high correlation value and BPA adsorption on MWCNT followed the Langmuir isotherm model.

“…Several nanocomposite sensors have been developed for Cr(III) monitoring [ 30 , 134 , 135 , 136 ]. In fact, ZAHRA HEIDARI et al [ 134 ] reported a nanocomposite electrode based on MWCNT/Zeolite for Cr(III) sensing. Zeolite was used as a selective ionophore and MWCNTs for their attractive chemical and physical properties such as high chemical stability, good conductivity, good mechanical strength and maximum specific surface area [ 2 ].…”

The extensive use of chromium by several industries conducts to the discharge of an immense quantity of its various forms in the environment which affects drastically the ecological and biological lives especially in the case of hexavalent chromium. Electrochemical sensors and biosensors are useful devices for chromium determination. In the last five years, several sensors based on the modification of electrode surface by different nanomaterials (fluorine tin oxide, titanium dioxide, carbon nanomaterials, metallic nanoparticles and nanocomposite) and biosensors with different biorecognition elements (microbial fuel cell, bacteria, enzyme, DNA) were employed for chromium monitoring. Herein, recent advances related to the use of electrochemical approaches for measurement of trivalent and hexavalent chromium from 2015 to 2020 are reported. A discussion of both chromium species detections and speciation studies is provided.

“…Recently ionselective electrodes proved promising alternative as these provide linear dynamic range, fast response time, non-destructive analysis and online analysis. To develop a good sensitive sensor for chromium ion determination [17][18][19][20][21][22][23][24], many efforts were done using various neutral ionophores. However, reported sensors showed narrow working concentration range, non-Nernstian response and high response time [25][26][27][28] and significant interference from foreign ions Egyptian Journal of Chemistry http://ejchem.journals.ekb.eg/ ________________________________________________ Egypt.…”

A thiol amine surfactant, poly-3-(dodecylthio)-N-hexadecylacrylamide (iphI) was prepared and characterized using spectral methods of analyses. The proposed potentiometric method was based on the fabrication of iphI-modified carbon paste (iphI-MCPE; electrode IV) sensor. Fast, highly sensitive and wide dynamic range potentiometric sensor was constructed using the prepared ionophore to quantify Cr(III) ions in spiked water sample under optimum conditions. The electrode (IV) exhibited an excellent Nernstian response to Cr(III) ion ranging from 4.8 × 10-7 to 1.0 × 10-2 mol L-1 with a detection limit of 4.8 × 10-7 mol L-1 and a slope of 19.59±0.45 mV decade-1 over a wide pH range (2.0-8.0) with a fast response time (7 s) at 25 oC. The proposed sensor showed fairly good discriminating ability towards Cr(III) ion in comparison with many hard and soft metal ions. The developed electrode has been successfully applied for the Cr(III) ions potentiometric determination in different water samples. The results obtained compared well with those obtained using atomic absorption spectrometry.
