“…To improve the suspension concentration of free nanotubes and the adsorption performance of the CNTs, the modification of their surface is the most useful method, which not only enhances the dispersion behavior but also provides more binding sites for the adsorption of metal ions and organic pollutants (Gupta et al, 2016;Hadavifar et al, 2014). For example, Baghayeri et al (2021) has synthesized PAMAMs covalently functionalized magnetic multi-walled carbon nanotubes for the determination of trace As(III) in an aqueous matrix. The CNTs-coated polyamine dendrimers (PAMAMs) were prepared and used as adsorbents (the composite diagram shown from Figure 3) (Hayati et al, 2017;Hayati et al, 2018), and the results exhibited that PAMAMs-CNT could be effectively used as a novel super absorbent for heavy metal adsorption in multicomponent systems.…”

In recent years, the problem of heavy metal pollution has become increasingly prominent, so it is urgent to develop new heavy metal adsorption materials. Compared with many adsorbents, the polyamide-amine dendrimers (PAMAMs) have attracted extensive attention of researchers due to its advantages of macro-molecular cavity, abundant surface functional groups, non-toxicity, high efficiency and easy modification. But in fact, it is not very suitable as an adsorbent because of its solubility and difficulty in separation, which also limits its application in environmental remediation. Therefore, in order to make up for the shortcomings of this material to a certain extent, the synthesis and development of polymer composite materials based on PAMAMs are increasingly prominent in the direction of solving heavy metal pollution. In this paper, the application of composites based on PAMAMs and inorganic or organic components in the adsorption of heavy metal ions is reviewed. Finally, the prospects and challenges of PAMAMs composites for removal of heavy metal ions in water environment are discussed.

“…This approach showed several advantages, including low cost, rapidity, adequate sensitivity, and reusability [ 124 ]. Baghayeri et al [ 125 ] proposed the synthesis, classification, and application of an electrochemical sensor for the detection of As 3+ at trace levels in water samples in which magnetic multiwall carbon nanotubes covalently functionalized with PAMAM dendrimer (MMWCNTs-D-NH 2 ) were produced, generally characterized and presented as recognition elements in sensor preparation. The electrochemical properties of the invented sensor were investigated using square wave anodic stripping voltammetry (SWASV) measurements at various As 3+ concentrations.…”

In recent years, there has been much interest in developing advanced and innovative approaches for sensing applications in various fields, including agriculture and environmental remediation. The development of novel sensors for detecting heavy metals using nanomaterials has emerged as a rapidly developing research area due to its high availability and sustainability. This review emphasized the naturally derived and engineered nanomaterials that have the potential to be applied as sensing reagents to interact with metal ions or as reducing and stabilizing agents to synthesize metallic nanoparticles for the detection of heavy metal ions. This review also focused on the recent advancement of nanotechnology-based detection methods using naturally derived and engineered materials, with a summary of their sensitivity and selectivity towards heavy metals. This review paper covers the pros and cons of sensing applications with recent research published from 2015 to 2022.

“…It is, in fact, absolutely necessary to modify the conventional electrodes such as carbon paste ( Bijad et al, 2017 ), screen-printed electrodes ( Jaiswal et al, 2017 ), and glassy carbon electrodes with a suitable agent ( Muthumariappan et al, 2017 ; Velmurugan et al, 2020 ; Karimi-Maleh et al, 2021 ). Electrochemical Multi-walled carbon nanotubes (MWCNT), largely used to modify the surface of electrodes for many applications ( Mani et al, 2017 ; Beitollahi et al, 2018 ; Roy et al, 2018 ; Rui et al, 2020 ; Shaikshavali et al, 2020 ; Baghayeri et al, 2021a ); are considered as an ideal choice thanks to their interesting properties. Moreover, they can be combined with metallic nanoparticles, metal organic framework or conducting polymers in order to enhance the sensitivity towards nitrite determination in different matrices ( Thirumalraj et al, 2016 ; Wan et al, 2017 ; Yu et al, 2019 ; Baghayeri et al, 2020a ; Salagare et al, 2020 ).…”

A novel electrochemical sensor based on conducting polymer and multi-walled carbon nanotubes was reported for the detection of nitrite ions (NO2−). The hybrid material poly 1,8-Diaminonaphthalene (poly 1,8-DAN)/functionalized multi-walled carbon nanotubes (f-MWCNT) was prepared by using a simple electrochemical approach which is based on the deposition of functionalized multi-walled carbon nanotubes (f-MWCNT) on the surface of the electrode followed by the electropolymerization of 1,8-DAN using cyclic voltammetry. The morphology and the electro-catalytic properties of the obtained electrodes were investigated with Fourier Transform Infrared Spectroscopy (FTIR), Transmission Electron Microscopy (TEM), Cyclic Voltammetry (CV), and Electrochemical Impedance Spectroscopy (EIS) showing an improvement of the electronic transfer due to the synergic effect between the proprieties of poly 1,8-DAN and f-MWCNT. Under the optimum experimental conditions, the poly 1,8-DAN/f-MWCNT/CPE exhibited excellent electro-catalytic activity towards nitrite detection. The nitrite anodic peak potential decreased by 210 mV compared to the bare carbon paste electrode. The calibration plot of nitrite detection was linear in the range of concentration from 300 to 6500 nM with a low detection limit of 75 nM.
