| Abstract: | The samples were digested by temperature-controlled and pressure-controlled microwave.The amount of germanium was determined by graphite furnace atomic absorption spectrometry with Ni（NO3）2 as matrix modifier.Deuterium lamp was used to remove the background for determination of trace elements germanium in Mengshan scorpion under the wavelength of 265.2nm.Under the optimum conditions,the detection limits was found to be 0.30μg/L for germanium.RSD of the method was in the range of 1.2%—3.1%,and recoveries were in the range of 88.9%—104.5%.The use of matrix modifier makes germanium stabilize,the germanium loss has decreased,graphite furnace process is optimized,the method is precise. |
