Özet:

 

An alternative sample preparation method has been developed for  destructive analysis of magmatic rock sample.  The method simply  included the crushing, HF treatment and 1% HCl leaching steps of the  rock samples under ultrasonic effects.  There is no need to exhaust  all of the sample through the operation.  A reproducible and  representative, partial recovery of an analyte was expected in a  procedural sequences consisting of strictly defined steps.  The  changes in analyte recoveries were investigated by sample grain size,  sample mass, applied ultrasonic power and sonication time.  The  optimum recovery conditions were examined.  In addition, the kinetics  of the dissolution under ultrasonic effects were studied.  It was  observed that the process followed second order kinetics.  The  accuracy of the ultrasonic leaching method (CULM) was tested by  application on standard reference material (SRM) and a recovery rate  was defined as K1= CULM/CSRM.  Another recovery rate,  K2, was also defined according to the result of the conventional  dissolution method (CDM), that is, K2= CULM/CCDM.  The  accuracy and the precision of the method are comparable with those of  the conventional methods;  91.3% < K1, Mn.
