Interferences Associated with the Determination of Calcium by Atomic Absorption

Volume 20, Number 4 (Aug. 1966) Page 214-218

Dickson, Richard E.; Johnson, C.M.

The determination of calcium in solution by atomic absorption is quite satisfactory, provided that potential interferences are overcome. Ionization enhancements and refractory-compound formations are the most important interferences found in the analysis for calcium. Protecting agents and the method of additions can both be used to overcome these interferences.
