Abstract
A procedure for the determination of orthophosphate and condensed phos phates in castables is proposed. The sample is calcined with sodium ca rbonate and leached with deionized water. After removing the interferi ng components from the matrix by cation-exchange, the sample solution is subjected to ion-chromatographic determination with gradient elutio n and conductivity detection. Recoveries are within 84-89% with a rela tive standard deviation of less than 3.6%.
