Using flame atomic absorption spectrometric method for the determination of calcium magnesium phosphate in the cadmi- um content, the paper discussed the working condition of instrument, digestion reagent selection and the determination of recoveries of standard addition. In the best working condition, calcium magnesium phosphate determination of cadmium content in an average value of 1. 750 9 g / g, the relative standard deviation ( RSD ) was 5.6 %, the recovery rate was 94.50 % - 103.71%.
