| Abstract: | This paper studies a sequential scan ICP-AES method for the determination of Al,Ca,Cd,Co,Cr,Cu,Fe,Mg,Mn,Mo,Ni,Ti,V and Zn in high purity graphite ash to meet the requirements of those studying the purification of graphite for rapid judgement of purification efficiency. All analytical lines of these fourteen elements were experimentally selected according to the element contents in the samples. The base line background noise interference caused by the main elements' emission lines was eliminated by using the profile function of the ICP-AES. The results were corrected with the interference coefficient method. The detection limit, precision and accuracy were determined for all the fourteen elements. The results indicate that this analytical method is satisfactory for analyzing high purity graphite ash samples. |
