In order to evaluate the data obtained by atomic emission spectrometric analy- sis after ultrasonic extraction, destructive analysis of some certified rock samples em- ploying ultrasonic waves was applied to two elements, Na and K, and the recovery rates were defined. The recovery ratio as K1 =C ULM/CCRM was defined for the ultrasonic leaching method (CULM) and the certified reference materials (CRMs). Another recov- ery ratio, K2 was also defined from the results of the conventional dissolution method (CCDM), that is K2 ,C ULM/CCDM. The accuracy and precision of the method were com- parable with those of the conventional methods. The obtained recoveries were between 90.0 % < K1, Na < 106.1 and 90.0 % < K2, Na < 103.0 % for Na and 92.3 % < K1, K < 103.2 and 92.3 %
