N2 - The complexation of di-n-butyl phthalate (DBP) by two different series of water-soluble calixarenes {p-sulfonatocalix[n]arenes [SCAn (n = 4, 6, and 8)] and calix[n]arene-O-propane-3-sulfonate [CAnPS (n = 4, 6, and 8)]} and the DBF adsorption ability of chitosan beads modified with SCAn and CAnPS were investigated. The six- and eight-membered calixarenes (SCA6, SCA8, CA6PS, and CA8PS) could include DBP in their hydrophobic cavities in the homogeneous aqueous phase. The amount of DBP adsorbed by chitosan beads modified with SCA6 was approximately five times as large as that for unmodified chitosan beads. On the other hand, the chitosan beads modified with SCA8 show the nearly the same amount of adsorbed DBP as compared to unmodified chitosan beads. In the case of the chitosan beads modified with CAnPS, no correlation was observed with the DBP inclusion capability of CAnPS.
