[Study on the determination of microelements in forest frog by inductively coupled plasma atomic emission spectroscopy].

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.
