Conteúdo: |
The turbidimetric determination of sulphate as barium sulphate has been adapted to the continuous flow injection procedure of Ruzieka and co-workers. The effect of reagent comporition, reagent flow-rates and lenght of mixing coils have been investigated. Optimum conditions were established for the determination of sulphate in natural waters and in plant digests. The results agree satisfactorily with those obtained by a standard turbidimetric method and analyses can be carried out at a rate of up to 180 samples per hour. |
