摘要:采用电感耦合等离子体发射光谱法建立磷酸铁锂中铁、磷含量的分析方法。分别对样品处理条件和仪器工作参数进行考察,以线性内插法建立标准曲线,用标准溶液对连续测定的结果进行实时校正,可以有效提高测试结果的准确度和精密度。样品用盐酸溶解,待测元素的分析线分别为Fe 239.562 nm,P 214.914 nm。铁、磷的加标回收率分别为98.9%、100.7%,测定值的相对标准偏差分别为0.34%、0.38%(n=10),采用标准溶液校正法后测试结果稳定性得到了显著提高。该方法的测试结果与标准方法的测试结果基本一致,满足磷酸铁锂样品中铁磷含量的测定要求。 
Abstract:Inductively coupled plasma emission spectrometry was used to determine the content of iron and phosphorus content in lithium iron phosphate. The sample treatment condition and the instrument working parameters were studied. The standard curve was established by linear interpolation and the results of continuous measurement were corrected by standard solution in real time, which could e ffectively improve the accuracy and precision of the testing results. The sample was dissolved by hydrochloric acid and the analysis line of each element was Fe 239.562 nm and P 214.914 nm. The recoveries of Fe and P were 98.9% and 100.7%, respectively. The relative standard deviations of iron and phosphorus determination results were 0.34% and 0.38%(n=10), respectively, the stability of testing result was improved by using standard solution correction. The experimental results were basically consistent with which obtained by the standard method, which can meet the requirements of the determination of iron and phosphorus content in lithium iron phosphate samples.
