��-cyclodextrin polymer in textile wastewater

Cyclodextrins (?-CDs) are D-glucose macrocycles that resemble hollow truncated cones and can be produced inexpensively from side to side enzymatic starch stop working. The three principal types of cyclodextrins are ?-CD (diameter of cavity: 0.57 nm) ?-CD (diameter of cavity: 0.78 nm) and ?-CD (diameter of cavity: 0.95 nm) which contain 6-8 glucose molecules in that order. Due to their cup-like shape and hydrophobic interior cavity ?-CDhave a remarkable ability to create host-guest complexes with hundreds of chemical molecules.
