“…[ 30 ] Preparation of TG composite with suitable fillers is another option for the functionalization, in which the mechanical and other physical properties are improved. [ 35 ] Another process for functionalization is the designing of interpenetrating polymer networks (IPN) of TG hydrogels. [ 36 ] These hydrogels have gained large attention due to the formation of double or multiple network, where different monomers are polymerized in presence of hydrogel matrix.…”

Tragacanth gum is a novel polysaccharide which offers interesting features in terms of high hydrophilicity, good biocompatibility, and biodegradability. The engineering of hydrogels requires careful designing of their macromolecular structures so that desirable features may be incorporated into the material. Graft polymerization has come up as an interesting approach to develop molecules for drug delivery, wound care systems, and infection‐resistant materials. The most important aspect of graft functionalization is the proper control over physico‐chemical properties of the grafted matrix. The extent of functionalization may be governed by the grafting parameters and may lead to the chemical designing of the molecule in a controlled manner. This opens up enormous possibilities of developing materials for a wide range of applications as advanced materials.

“…With the addition of other substance that can form the bond via conjugation with graphene, electrocatalization as well as electroluminescence (ECL) can be facilitated. This modiied graphene derivatives can be use satisfactorily in both waste water treatment via adsorption [20] as well as analysis in only one step [21] in addition to the development of new bateries [21,22] and improvement of antibacterial properties [23].…”

Due to all the advantages of low cost, speed, and simplicity, electrochemistry has always represented a perfect choice to be selected in quantitative analysis particularly in the case of metal ions but with the drawback of speciicity and sensitivity. With the arrival of nanomaterials, the problem of sensitivity and limit of detection has been overcome and a great variety of applications of electrochemistry especially in trace analysis are highlighted.Layers of materials can be arranged and manipulated to make the methods more speciic to targeting analytes The opportunity is there for both older and newer methods to be beneicial in a large number of applications with superb analytical performance. This knowledge of modiied electrodes can inspire newer and greater innovative applications of electrochemistry with the promising extension to other areas under current interests.

“…; Yuan et al . ; Sahraei & Ghaemy ). Over the past few years, much attention has been paid to utilise various bio‐materials such as agricultural and biological waste materials as adsorbent for heavy metals due to the increasing demand for new, cost effective and environment friendly processes for the removal and recovery of these metals from industrial effluents (Dhir ; Feizi & Jalali ).…”

In this research, the possibility of simultaneous removal of lead, cadmium and copper divalent ions from water samples through the use of Sepia pharaonis endoskeleton powder (SPEB) as bio‐material, was investigated. The bio‐sorbent was characterised by Fourier transform infrared spectrum (FT‐IR), atomic force microscopy (AFM) and X‐ray fluorescence (XRF). The different factors affecting the bio‐sorption process were studied. Langmuir and Freundlich isotherm models were applied to analyse the experimental data. The kinetic studies showed that the pseudo‐second order model kinetics were compatible with the investigated systems. It was found that under optimal conditions, this bio‐sorbent was efficient in the uptake of these heavy metal ions from both mono and multi‐metal solutions, and high removal percentages were achieved. This study verified the potential ability of SPEB as an efficient natural adsorbent for removal of Pb(II), Cd(II) and Cu(II) ions from river, tap and mineral water samples.
