Synthesis and characterization of hydroxypropyl-β-cyclodextrin (HP-β-CD) conjugated magnetic nanoparticles and its adsorption of crystal and methyl violet dye

Organic dye contaminants have received increased concerns in recent years because of the fast development of industry processing. Hence, removal of the dye contaminants prior to their discharge into the environment is necessary. The most notable feature of CD is its ability to form host−guest complexes with a wide range of molecules including dyes,1, 2 due to its special molecular structure. Because of its low cost, easy regeneration, and effectiveness, adsorption is regarded as a useful technique. Crystal violet and Methyl violet is a family of organic compounds that are mainly used as dyes. In the present study, we used HP-β-cyclodextrin conjugated magnetic nanoparticles due to easy and inexpensive synthesis and separation much easier with the use of a magnet is done to remove dye
