摘要:

The sample is prepared by grinding, blending, and ashing. Dissolution of the ash is accomplished by a multistep acid digestion. The sample solution is analyzed by atomic absorption for eleven elements. A spectrophotometric analysis is used to determine titanium. The relative standard deviation (RSD) for all twelve elements ranged from 2.44 to 122%. Aluminum, copper, and lead analysis produced the high RSD values.
