摘要
文中探究了使用几种常规方法测试磷酸铁锂(LiFePO_4)中全铁含量的优劣,借此在实际生产及科学研究中,根据自身要求及条件选择最佳的测试方法来检测磷酸铁锂中全铁的含量。本试验分别采用邻菲罗啉分光光度法、电感耦合等离子体发射光谱法(ICP-OES)、原子吸收光谱法(AAS)、自动电位滴定法以及EDTA络合滴定法测定同一试样中全铁含量,对测试结果展开分析与讨论。
The advantages and disadvantages of several conventional methods to determine the total iron content in the lithium ferric phosphate （LiFePO4） were investigated in this paper. According to the requirement of the production control and scientific research, the best method was applied to determine the total iron content in the LiFePO4. The determination of total iron content in LiFePO4 by O-Phenanthroline spectrophotometric, inductively coupled plasma optical emission spectrometer （ICP-OES）, atomic absorption spectrophotometry （AAS）, automatic potentiometric titration or EDTA coordinate titration was analyzed and discussed.
