Microwave-enhanced synthesis of magnetic porous covalent triazine-based framework composites for fast separation of organic dye from aqueous solution

Effective removal of methylene blue from aqueous solution using a new magnetic iron oxide nanosorbent prepared by combustion synthesis

“…The results are in accordance with the literature data (Giri et al 2011;Zhang et al 2011;Raj et al 2013;Paşca et al 2014a;Ferrero 2015), showing the increase of the amount of MB adsorbed at equilibrium, and the decrease of the percentage of dye removal with increasing initial dye concentration indicated that the dye removal is concentration dependent.…”

“…Similar results for the adsorption kinetics of MB was also reported by Zhang et al 2011 In adsorption systems where there is the possibility of intraparticle diffusion being the rate-limiting step, the intraparticle diffusion approach described by Weber and Morris (1963) is used (Eq. 5):…”

“…A growing number of researchers are attempting to develop new adsorbents with magnetic properties for the removal of different pollutants from wastewater due to the advantage of easy separation of solid-liquid phases (Giri et al 2011;Zhang et al 2011;Wu et al 2011). Due to their strong adsorption capacity, low cost, chemical stability, low toxicity, easy separation and excellent recycling capability, iron oxide materials have a great potential as valuable adsorbents for the removal and recovery of many types of contaminants from aqueous solution (Tang and Lo 2013;Xu et al 2012).…”

Facile room-temperature solution-phase synthesis of a spherical covalent organic framework for high-resolution chromatographic separation

“…[10][11][12][13][14][15][16] The methodologies involved in the fabrication of COFs usually need harsh experimental conditions such as reaction in a sealed pyrex tube, inert atmosphere, and long time. [17][18][19][20] In addition, most synthesized COFs require special care in regard to their moisture instability.…”

Three novel triazine-based materials with different O/S/N set of donor atoms: One-step preparation and comparison of their capability in selective separation of uranium

“…Covalent triazine frameworks (CTFs) are an emerging class of polymers, which are prepared by a trimerization reaction of carbonitriles to form triazine rings [41][42][43][44]. Due to their diverse functionality, extremely high thermal and chemical stabilities [45][46][47][48], CTFs have been applied to gas storage and separation, catalytic supports, adsorbents of ionic dyes etc.…”
