摘要：

In this paper, a method for the determination of Orange 11 has been established and the supramolecular system of Orange 11 with cyclodextrins has been studied by polarography. A sensitive and stable linear-sweep voltammetric peak was obtained at -364 mV (vs SCE) in HAc-NaAc (pH 3.62) buffer solution. The peak current (i(p)") is proportional to the concentration over the range 1 x 10(-8)-1 x 10(-3) mol l(-1) (r = 0.9887-0.9986) and the limit of detection is 2.0 X 10(-9) mol l(-1). The mean recovery of Orange 11 was 99.1% and the relative standard deviation was 1.6%. Orange 11 can form 1:1 inclusion complex with 6 CDs. The inclusion constants were calculated by "electric current method". Furthermore, the inclusion ability of different kinds of cyclodextrins was compared, which provided some elemental data for application of Orange 11 and cyclodextrins. (C) 2004 Elsevier Ltd.
