| Abstract: | Acidize sample that has been subjected to alkali fusion.Determine the content of germanium in phosphate medium with potassium borohydride as reducing agent,by using atomic fluorescence spectrometry.The detection limit of the method is 0.1μg/g.It was used to test 6 national level 1 soil samples and gave results consistent to recommended values.Respective test of 12 times gave RSD all below 10%. |
