摘要
采用等离子体原子发射光谱法(ICP AES)测定精对苯二甲酸(PTA)中微量金属元素。讨论了影响因素,优化了操作参数。钠、铁、钴、锰、镍、铬六种元素回收率在94.0%～104.0%之间。此法对其它有机体中的金属元素测定有参考价值。
ICP-AES analysis was applied to the simultaneous determination of microamounts of six metal elements, i.e. sodium, iron, nickel, chromium, cobalt and manganese, in refined p-phthalic acid. Various influential factors were studied and the working parameters of the instrument were optimized. A comparative study with the AAS method was made and consistent results were obtained. RSD′s (n=5) for determination of the above mentioned elements were found to be in the range from 3%～10%, and recoveries obtained were in the range of 94.0%～104.0%. The results of this work may be taken as reference in the analysis of other chemicals.
