“…Currently, the iron oxide nanoparticles are among favorable choice for treatment of multiple ground contaminants, for example, polychlorinated biphenyls (PCBs), chlorinated organic solvents, and organochlorine pesticides. This feature is due to the fact that iron oxide nanoparticles are easily transportable through ground water, non-toxic to environment and human health, and thus can be injected into the polluted area and left to stay there for long periods of time [ 11 ]. The researchers demonstrated that aluminium and iron oxides are the most commonly applied materials for As removal [ 12 , 13 ].…”

This work reveals the As(V) adsorption behaviors onto iron oxide (Fe3O4) nanoparticles modified activated carbon (AC), originally developed from biochar (BC), as a green adsorbent denoted by FAC. Since FAC has abundant surface functional groups and a desired porous structure that is favorable for the removal of As(V) in contaminated water, FAC has greatly enhanced the As(V) adsorption capacity of the original BC. Various methods were employed to characterize the FAC characteristics and adsorption mechanism, including pHpzc determination, BET specific surface area, elemental analysis (EA), and scanning electron microscopy (SEM). Results show that the AC surface was successfully modified by iron oxide nanoparticles, enhancing the porosity and specific surface area of original adsorbent. Batch adsorption tests indicated a well-fitted Langmuir model and pseudo-second-order model for As(V) adsorption. Additionally, the highest adsorption capacity (Qmax = 32.57 mg/g) by FAC was higher than previously reported literature reviews. Until now, no article was conducted to research the effect of carbon surface chemistry and texture on As removal from waters. It is required to obtain a rational view of optimal conditions to remove As from contaminated water.

“…are the most widely used for metal nanoparticles synthesis. [17][18][19][20] Among them, the sol-gel method is a mild method to prepare nanomaterials, and is the most widely used at present. To solve the dispersibility of nanoparticles, the sol-gel method was used to generate MnO 2 nanoparticles on the surface of Diatomite (Dia).…”

Nanoparticle enhancement has been used as an effective means to improve the performance of biomass adhesives. However, there is an inevitable problem of stress concentration caused by particle agglomeration and thus the adhesive layer is susceptible to damage. Therefore, in this paper, a sol-gel method was used to generate uniformly distributed manganese dioxide (MnO 2 ) nanoparticles on the surface of diatomite (Dia) and used for the modification of soybean meal based wood adhesives. The results showed that MnO 2 nanoparticles have been successfully anchored on the surface of Dia during the sol-gel process without agglomeration. MnO 2 /Dia particles could fill in the adhesive gaps and form hydrogen bonds with soy protein molecules, which ensured that the adhesive wet shear strength was increased by 33% to 0.89 MPa. This study provided an idea for the preparation of highly dispersed nanoparticle reinforced adhesives.

“…Several amino-functional substrates able to remove heavy metals from water have been studied. [16][17][18][19][20][21] Particularly, N-methyl-D-glucamine (NMDG) (Figure 1) is well known for its high affinity for borate ion under alkaline conditions. 22 In several studies, it was found that NMDG also exhibited high affinity and selectivity for arsenate ions in aqueous solutions at neutral or acidic pH.…”

The N-methyl-D-glucamine moieties exhibit high ability and selectivity toward arsenate ions in water by a complexation mechanism that involves their hydroxyl groups. In this work, the syntheses of two monomers containing N-methyl-D-glucamine, namely 4-vinylbenzyl-N-methyl-D-glucamine (VbNMDG), and N-methyl-D-glucamine methacrylamide (MNMDG) were studied. Different synthetic routes were considered in order to obtain liquid monomers able to polymerize and selectively capture arsenic. Furthermore, the incorporation of protective groups like trimethylsilyl moieties in the molecular structure was assessed to prevent transfer reactions during further polymerization. After polymerization, hydroxyl groups were deprotected using hydrofluoric acid. Following this methodology, structured microporous polymeric films based on colloidal crystal templates were prepared. NMR and FTIR techniques were used to follow the reactions and to determine the chemical structure of the obtained products. The morphology of materials was characterized by SEM. The performances of the developed polymeric films to selectively capture arsenic were determined. Films showed an improved and reproducible sensitivity to arsenic detection exhibiting high values of arsenic capturing capability (around 90%).
