Phosphate ions interfere with the atomic absorption spectrometric determination of calcium due to the formation of calcium phosphate that does not easily break up into atoms in the natural gas/air flame. The interference can be minimized by doing the following except A. using a natural gas/oxygen flame B. adding an excess amount of strontium chloride C. adding EDTA to the sample D. adding an excess amount of sodium sulfate E. adding an excess amount of lanthanum(III) chloride
