Abstract

This study was conducted to compare the pyrocatechol violet (PCV) and 8-hydroxyquinoline (Oxine) methods for the determination of monomeric Al fractions. A strongly acidic cation-exchange resin was used in automated PCV and nonautomated oxine procedures to separate aqueous Al into inorganic (Labile) and organic (nonlabile) monomeric forms. Results showed good agreement between the two methods, suggesting that the PCV method is an acceptable alternative to the oxine method for the estimation of monomeric Al. In addition, the cation-exchange column fractionation procedure was verified using an F ion-selective electrode. from Authors
