发明名称	一种测定可溶性锂化合物中钾和/或钠含量的方法
摘要	一种测定可溶性锂化合物中钾和/或钠含量的方法，该方法包括用原子吸收光谱法测量可溶性锂化合物待测样品水溶液中钾和/或钠的吸光度，然后将该吸光度与钾和/或钠的工作曲线比较，确定该可溶性锂化合物待测样品水溶液中钾和/或钠的浓度，按照钾或钠含量＝100％×(可溶性锂化合物待测样品水溶液浓度×可溶性锂化合物待测样品水溶液总体积)/可溶性锂化合物待测样品总质量，计算可溶性锂化合物中钾和/或钠的含量，其中，所述可溶性锂化合物待测样品水溶液和钾和/或钠标准水溶液中还均含有有机溶剂。本发明提供的测定可溶性锂化合物中钾和/或钠含量的方法大大降低了测量误差，提高了测量结果的准确性。
