Abstract

Sets out a flame atomic absorption spectrometric method for the determination of calcium in waters in the concentration range 0.2 to 4 mg/L. This edition is technically identical to AS 2526-1882, except for the restriction in the application range, the recommendation on the use of cellulose acetate filters in the sampling procedure and minor editorial formatting changes.

Scope

This Standard sets out a flame atomic absorption spectrometric method for the determination of filtrable calcium in natural and waste waters. A procedure for the determination of non-filtrable calcium is described in Appendix A. Waste-waters and raw water samples are likely to contain suspended materials and may require pretreatment before analysis. Details of such pretreatment are given in AS 2031.1 and in Appendix A of this Standard.
This method is applicable to the direct determination of calcium in the concentration range 0.2 mg/L to 4 mg/L in the test solution.
