Adsorptive removal of adsorbable organic halogens by activated carbon

Current research mainly focuses on the reduction of adsorbable organic halogen (AOX) sources, while studies on AOX monitoring and management in the environment are scarce. Organic pollutants in water are mainly fixed by sediments. Thus, in this paper, activated carbon was used to simulate the adsorption of AOX by sediments. AOX volatilization and degradation were also studied to exclude their effect on adsorption. Micromolecule chlorides were more easily volatilized and degraded than chlorobenzene and chlorophenol. The adsorption of activated carbon to AOX in bleaching wastewater was also studied and the optimum conditions for AOX removal were elucidated (particle size, 62 mum; time, 120 min; pH, 2.5; temperature, 40C; and activated carbon dosage, 1.75 g l-1). AOX adsorption by activated carbon is a chemical process. Hence, the chemical compositions of the bleaching effluent with and without adsorption were analysed by GC-MS. The results revealed that activated carbon exhibits a good AOX removal effect, thereby providing a theoretical basis for monitoring the AOX distribution in the environment.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application In Synthesis of 3,6-Dichloropyridazine, you can also check out more blogs about141-30-0

Transforming Polybutadiene with Tetrazine Click Chemistry into Antioxidant Foams That Fluoresce with Oxidation

The extent to which oxidative degradation of macromolecules can be delayed is generally limited by the low solubility of antioxidants in most polymers. This can be surmounted by synthesizing macromolecules with covalently attached antioxidant functionalities, but these are frequently expensive. Here, we demonstrate a simple click modification of polybutadienes (PDB) with 3,6-dichloro-1,2,4,5-tetrazine (DCT) that, in addition to modifying and stiffening the polymer chains, releases nitrogen gas to foam the solidifying polymers and generates dihydropyridazine groups that transform them into macromolecular antioxidants. Tetrazines react by a cycloaddition/cycloreversion reaction (Carboni-Lindsey reaction) with the C=C bonds to install 1,4-dihydropyridazine groups that increase the mass and rigidity of the butadiene macromolecules. The 1,4-dihydropyridazine group is an effective antioxidant that donates two hydrogen atoms per ring to combine with radicals and forms an aromatic pyridazine ring whose white fluorescence under UV permits visual monitoring of oxidation. Foams made by reacting liquid hydroxyl-terminated polybutadienes with DCT stabilize with thermoset formation through substitution reactions between the hydroxyl and dichlorodihydropyridazine groups.
