Adsorption is one of the efficient methods in humic acid removal.Many solid materials as adsorbents have been investigated, which include activated carbons, natural and synthetic zeolites, clays and modified clay minerals, alumina, resins, chitosan, fly ash, aminated polyacrylonitrile fibers and Mg/Al layered double hydroxides[4-7].Moreover, Cucurbiturils are one kind of new functional materials compounds which possess a hydrophobic cavity accessible through portals surrounded by polar carbonyl groups capable of including a variety of hydrophobic and the appearance of hydrophilic[8].
