“…The content of Cr(VI) was determined using 1,5-diphenylcarbazide by a U-3010 UV-vis spectrophotometer (Hitachi, Tokyo, Japan) (λ = 540 nm) [ 32 ]. The concentration of aniline in samples was measured using a U-3010 UV-vis spectrophotometer (Hitachi, Tokyo, Japan) (λ = 230 nm) [ 33 ].…”

Recyclable nanomaterials are in great need to develop clean technology for applications in the removal of water contaminants. In this work, easily separable montmorillonite/Fe3O4/humic acid (MFH) nanocomposites were fabricated through a facile hydrothermal route. It was found the adsorption ability and stability of MFH was significantly enhanced due to the synergistic effects between montmorillonite, Fe3O4 nanoparticles and humic acid. The MFH nanocomposites are highly efficient and recyclable as they can remove at least 82.3% of Cr(VI) and 95.1% of aniline in six consecutive runs. The adsorption mechanism was investigated by analyzing the kinetic parameters of pseudo first-order, pseudo second-order, and intraparticle diffusion models and describing the equilibrium isotherms of Langmuir and Freundlich models. Results indicated different adsorption mechanisms of Cr(VI) and aniline by MFH. The readily synthesized MFH nanocomposites can act as effective and practical materials for environmental applications.

“…Au nanotubules were prepared according to the modified method proposed by Menon and Martin. 28 The polycarbonate nanoporous filtration membrane was immersed in methanol for 5 min and then immersed in a methanol solution of 0.025 M SnCl 2 and 0.07 M tri?uoroacetic acid for 45 min. The membrane was then placed in methanol twice, each for 2.5 min, and then immersed in an aqueous ammoniacal AgNO 3 solution (0.029 M) for 5 min, followed by soaking in methanol for 5 min.…”

Gold nanochannels were prepared by plating electrolessly gold within the pores of polycarbonate filter membranes (PCTMs). These PCTMs with cylindrical Au nanotubules of uniform radius and high density can be used as a convenient model system to investigate the mechanism of particle transport through nanotubules. The transport properties of phenol through a modified Au nanotubule membrane were studied. The permeate flux of phenol transport through the nanotubule membrane can be spatially and temporally manipulated by controlling the magnitude and direction of the current applied across the separation cell, and the electroosmotic flow (EOF) was investigated by measuring the flux of phenol across the PCTM. The current values and modification of nanotubules affected the EOF generated inside the nanotubules. The permeation flux of phenol through the nanotubule membrane can be easily changed by modifying the Au nanotubules with Cl − or L-cysteine, and changing the direction of the applied current and the pH of the buffer solution used in mass transport experiments.

“…Although they have been studied for decades, narrow pores with charged walls exhibit surprising properties that are not yet fully understood. A study of the passive diffusion of low-molecular-weight organic compounds through a PET track-etched membrane with a pore size of 30 nm has shown that the transport of the compounds is realized through their accumulation in the membrane pores [31]. Aniline molecules, which are neutral in the bulk solution, diffuse through the membrane in cationic form.…”

This brief overview demonstrates how the ion track-based technology for micro-structuring polymeric materials that has been practised for decades is shifting to the nanometre scale in research and development applications. We present selected results of studies that have focused on the development of new nanoporous materials, especially membranes, performed recently at the Flerov Laboratory of Nuclear Reactions, Joint Institute for Nuclear Research (JINR).
