Application of beta cylodextrin in wastewater treatment

- Oct 23, 2018 -

Water pollution has become one of the major issues of global environmental problems, in which pesticides, chemical and other organic pollutants wastewater, especially the difficulty of treatment! At present, activated carbon adsorption is one of the most commonly used methods to remove organic pollutants from industrial wastewater. There are some problems in this method: 1. the adsorption speed is slow; 2. the removal effect of relatively hydrophilic organic pollutants is not obvious; 3. activated carbon regeneration needs a large amount of energy, and the cost is high, and the adsorption effect after regeneration is also obvious. It will decrease.

It is probably a good new choice for macromolecule beta cyclodextrin, which is almost insoluble in water. Cheap and continuous glucose supermolecule macromolecules are used to adsorb organic compounds. The principle of adsorbing organic pollutants by beta-cyclodextrin is to form host-guest complex with organic compounds. The adsorption rate constants of various organic pollutants are 15-200 times of that of activated carbon. After washing under mild conditions, they can be reused many times without degrading their performance. The beta cyclodextrin polymer has better performance for the removal of organic pollutants in the actual environment.
