Zeolitic imidazolate frameworks as capacitive deionization electrodes for water desalination and Cr(VI) adsorption: A molecular simulation study

Removal of Chromium Species by Adsorption: Fundamental Principles, Newly Developed Adsorbents and Future Perspectives

“…Due to the high nitrogen (N) content, covalent triazine frameworks (CTFs) were developed for the efficient adsorption of Cr(VI), and the strong ion-exchange interaction of quaternary N on CTF toward Cr(VI) was confirmed [ 184 ]. The metal–organic frameworks (MOFs), which are hybrid materials of organic ligands and metal ions or clusters, are another ideal material for Cr removal [ 185 ]. Due to the adjustable metal center, MOFs with an ordered porous structure could be further modified with specific ligands for more efficient and selective Cr(VI) removal [ 186 ].…”

Accelerating filtration by introducing an oscillation paradigm and its atomistic origin

“…Molecular dynamics simulation methods have proven to be very effective tools to study permeation processes in porous membranes involving molecular transport in conned spaces at the nanoscale. [48][49][50] The COF oscillation ltration system is shown in Fig. 1a and b.…”

Recent advances in the application of zeolitic imidazolate frameworks (ZIFs) in environmental remediation: a review

“…Recently, the adsorption of Cr(VI) on ZIFs has been widely investigated under different conditions. [213][214][215][216][217] The removal of Cr(VI) decreased somewhat with the increase in pH from 7.0 to 9.0 due to the competitive adsorption of CrO 4 − and OH − at Environmental Science: Nano Tutorial review high pH values. However, the relatively poor dispersion and difficulty in the separation of single ZIFs limit their regeneration and reusability in aqueous solutions as they easily aggregate together.…”
