    The mechanism of the synergistic sensitizing effect on the color reactions by β-cy-clodextrin (β-CD) with surfactants was studied with respect to the essence of inclusion complex formation by β-CD and the increase of the inclusion constant with ionic surfactant. It indicated that the surfactant (SF) included by β-CD producing SF-β-CD inclusion complex and then the enhancement of the effect of SF-β-CD on the color reagent and its corresponding colored complex are the main factors for the synergistic effect. However,the stability of the colored complex and the effect of SF-β-CD on the value of the reagent blank should also considered. An approximate estimating method for the synergistic tendency of the same color reaction by different ionic surfactants with β-CD was also proposed.
