title: [Sensitizing effect of nonionic microemulsion on phosphorus in crystal violet heteropoly molybdophosphoric acid].
abstract: A highly sensitive and convenient spectrophotometric method for phosphorus was developed. The sensitizing effect of nonionic microemulsion Triton X-100/n-C5H11OH/n-C0H20/H2O on the ion-association of heteropoly molybdophosphoric acid with crystal violet was higher than that of micelle Triton X-100/H2O. This result showed, by the measurement of distribution constant KD, that the binding constant K and the number of binding sites n of CV were related to the greater solubilization capacity of CV-PMo in nonionic microemulsion system than that in micelle.
