“…In general, the increase in the degree of grafting (DG) is proportional to the increase in reaction time. The longer the reaction time, the more likely the monomer molecules are to diffuse to the initiation sites and propagate polymer chains, resulting in increasing the degree of grafting 21 . Hence, extension of the reaction time from 20 to 180 min resulted in a corresponding increase in DG% from 120 to 340%, as can be seen in Fig.…”

“…Application of RIG in the emulsion phase attenuates environmental impact based on the use of a monomer mixture and water. Such an approach does not require toxic organic solvents, is affordable because it employs reduced levels of irradiation and monomers (reduce monomer consumption), and it affords a higher degree of grafting 21 .…”

The method of pre-irradiation grafting was used with the aid of electron beam (EB) accelerator to accomplish the grafting of polyamide 6 fibers (PA6) with glycidyl methacrylate (GMA). The extent to which GMA was grafted on PA6 was found to be markedly influenced by the absorbed dose of radiation and the reaction time of grafting. Trimethylamine (TMA) was afterwards employed for the functionalization of GMA-grafted fibers (PA6-g-GMA). A range of analyses (e.g., FTIR, FESEM, XRD, BET, and pHpzc) were carried out to determine the physiochemical and morphological properties of the fibrous adsorbent. p-Nitrophenol (PNP) adsorption from aqueous solution was conducted with the resulting TMA-(PA6-g-GMA) adsorbent. The adsorption behaviour of PNP on the fibrous adsorbent was clarified by investigating the adsorption kinetics and isotherm. According to the results, the adsorption of PNP on TMA-(PA6-g-GMA) reflected the pseudo-second order model. Meanwhile, the isotherm analysis revealed that the best description of the equilibrium data was provided by Redlich–Peterson model, followed closely by Langmuir isotherm model. The achieved adsorption capacity was highest at 176.036 mg/g. Moreover, the adsorption was indicated by the thermodynamic analysis to be spontaneous and exothermic. Regeneration and recycling of the adsorbent was possible for a minimum of five cycles with no reduction in adsorption capacity. It was concluded that the fibrous adsorbent could have applications for the removal of PNP at industrial pilot scale.

“…20 Radiation-induced graft polymerization (RIGP), a simple and robust method of developing functional materials, was used to synthesize the functional polymeric fiber. [20][21][22][23] When a polymer substrate is exposed to ionizing radiation, reactive radicals form on its surface from which vinyl monomers can grow, without the use of toxic initiators or catalysts. This results in the covalent attachment of polymer grafts with desired functionality onto an otherwise inert substrate.…”

Scandium is a rare earth element that has a wide range of uses in modern technology. The conventional recovery of scandium is commonly done by solvent extraction using organophosphorus compounds. This process however produces a lot of waste extractants. To circumvent this challenge, a model organophosphorus compound phenylphosphinic acid (PPI) was immobilized to a polymer support fabric to produce a Sc(III) adsorbent for high throughput scandium recovery with less waste generation. Polymer support (PP-g-PGMA)for the organophosphorus compound was synthesized using radiation-induced graft polymerization. Successful post-polymer modification of the PGMA grafts to attach PPI groups was carried out using 1 M PPI in isopropanol at 80 C for 4 h, achieving a maximum functional group density of 1.32 mmol/g. The obtained PP-g-PGMA-PPI fabrics were used in the batch Sc(III) adsorption experiments. The results showed that PP-g-PGMA-PPI effectively adsorbed low concentrations of Sc(III) at a pH of at least 2.0. More than 98% adsorption was achieved using 1 ppm Sc(III). The synthesized adsorbent was also shown to be selective for Sc(III) even in the presence of Fe(III) and Al(III) ions. PP-g-PGMA-PPI adsorbent fabrics are therefore promising alternatives to solvent extraction methods and ion-exchange granular resin technologies in the recovery of scandium.

“…In the past decades, propylene oxidation has been considered as the main route for the synthesis of acrylic acid (AA); AA is a crucial chemical raw material, which is used to produce many other important derivatives . However, during propylene oxidation, it is inevitable that large quantities of petroleum are consumed.…”

With CuBr2 as a co‐catalyst, the nickel‐supported two‐dimensional layered vermiculite (2D‐VT)‐based composite [Ni(NO3)2•6H2O/2D‐VT] was used as a precursor and applied to various calcination methods to produce catalysts. These catalysts were used in the acetylene carbonylation reaction to synthesize acrylic acid (AA). The catalysts were characterized and evaluated by scanning electron microscope (SEM), transmission electron microscope (TEM), X‐ray diffraction (XRD), X‐ray photoelectron spectroscopy (XPS), inductively coupled plasma (ICP), hydrogen temperature‐programmed reduction (H2‐TPR), nitrogen adsorption desorption analyzer (BET) and thermogravimetric analysis (TG). We found that the microwave (MW) radiation calcined catalyst (MW‐NiO/2D‐VT) exhibited better catalytic performance than the muffle furnace (MF) calcination catalyst (MF‐NiO/2D‐VT). This difference is observed owing to the fast speed of microwave radiation heating, short baking time, and the instantaneous formation of nano‐NiO particles that have better dispersibility and uniformity, which is more conducive to the performance expression of nickel oxide. Under the optimal reaction conditions, the yield of AA is 86.3%. During the reaction, the MW‐NiO/2D‐VT catalyst is more stable and produces less by‐deposits than the MF‐NiO/2D‐VT catalyst. Thus, MW‐NiO/2D‐VT is more conducive to improving the selectivity of AA. In addition, theoretical calculations show that the MW‐NiO/2D‐VT catalyst has a lower apparent activation energy, which kinetically explains why MW‐NiO/2D‐VT is an excellent catalyst.
