Developing efficient separation technologies for wastewater treatment and recovery of natural products is crucial in practical application. Covalent capture of supramol. gel materials and the further surface modification benefit for the improvement in adsorption performance. In the present paper, two kinds of supramol. gels, N,N’,N”-(3-methylpyridine) benzenetriamide (TMPTA) nanotube and N,N’,N”-(3-pyridyl) benzenetriamide (TPTA) nanofiber, were synthesized successfully by supramol. self-assembly of tripodal pyridines and then were further modified with α,α’-dibromo-p-xylene to obtain imidazolium-based gel materials, TMPTA-G-M and TPTA-G-M. They have stable porous structure and pos. charged surfaces with different morphologies. The synthesized gels are characterized by physico-chem. techniques, and the results show that the modification process does not cause significant changes in the morphol. TMPTA-G-M and TPTA-G-M are applied as adsorbents for the selective separation of anionic Congo Red (CR) and cationic dye Rhodamine B (RhB) from aqueous solutions Maximum adsorption amounts (qmax) on TPTA-G-M are 87.95 mg/g for CR and 85.83 mg/g for RB, and on TMPTA-G-M are 372.03 mg/g for CR and 45.64 mg/g for RB, resp. For the arsenate adsorption, TMPTA-G-M showed significantly better adsorption performance with qmax of 66.5 mg/g in solutions at pH = 9 in 10 min. Addnl., TMPTA-G-M is used for the selective separation of eugenol from eugenol acetate which coexist extensively in Clove oil, and it shows excellent adsorption selectivity for eugenol with qmax of 93.59 mg/g at pH = 11. The mechanism study suggests that the morphol. of the gels affects the distribution of charge and further affects the adsorption performance. And the adsorption may involve electrostatic interactions between adsorbent and adsorbate. The results indicate high adsorption ability and regeneration efficiency for TMPTA-G-M, implying the potential application in wastewater treatment and separation of natural product. In the part of experimental materials, we found many familiar compounds, such as 1,4-Bis(bromomethyl)benzene(cas: 623-24-5Computed Properties of C8H8Br2)
1,4-Bis(bromomethyl)benzene(cas: 623-24-5) belongs to organobromine compounds.Most of the natural organobromine compounds are produced by marine organisms , and several brominated metabolites with antibacterial , antitumor , antiviral , and antifungal activity have been isolated from seaweed, sponges, corals, molluscs, and others.
