- 中文摘要: The effects of addition of β-cyclodextrin (β-CD) to the neutral red-cetyltrimethylammonium bromide (CTAB) associates in pH 7 phosphate buffer solutions were investigated. Addition of β-CD to neutral red-CTAB association causes decomposition of the associate by displacement of neutral red with β-CD. The inclusion complex of CTAB with β-CD is more stable than that with neutral red. The results indicate that formation of inclusion complex of CTAB with β-CD prevents its association with neutral red, and inclusion complex formation ofβ-CD and neutral red in the presence of CTAB takes place after total consumption of CTAB. The competition ofβ-CD and neutral red on the interaction with CTAB can be used for the simple, rapid and sensitive spectrophotometric determination of β-CD.
