In this paper, several trace elements in the forest frog samples were investigated by inductively coupled plasma atomic emission spectrometry (ICP-AES). During the experiment 5.00 mL HNO3 and 0.50 mL HClO4 were added to the sample, which then remained 24 hours before being heated to 120 degrees C and solved. This method can not only meet the requirement of ICP-AES, but also has many merits, such as simplicity, rapidity, precision and economy. The range of relative error was 0.17%-10.0% and the range of precision was 0.43%-9.96% for these elements.
本文采用电感耦合等离子体原子发射光谱法(ICP-AES)对林蛙样本中的几种微量元素进行了研究。实验过程中,向样本中加入5.00 mL硝酸和0.50 mL高氯酸,放置24小时后加热至120℃使其溶解。该方法不仅能满足ICP-AES的要求,还具有简便、快速、精确和经济等诸多优点。这些元素的相对误差范围为0.17% - 10.0%,精密度范围为0.43% - 9.96%。
