| Abstract: | The trace calcium in graphite was determined by inductively coupled plasma atomic emission spectyometry（ICP-AES）.The measuring conditions were investigated.The detection limit of the method was 0.3866μg/g,and the quantitation limit of the method was 1.93μg/g under the optimized instrument conditions.The reliability of the method was tested by an Americian National Standard（ASTM C 560-2005） test method and the results were in agreement with the certified values with precisions of 0.347%—3.913%（RSD,n=10）.The method can meet the needs for fast and accurate determination of impurity element calcium in graphite. |
