研究了用石墨炉原子吸收光谱法测定灵芝饮料中痕量锗,提出了以NaOH、H_2O_2为消解液分解样品,采用NaOH+Ni(NO_3)_2混合基体改进剂在热解涂层石墨管中直接测定灵芝饮料中痕量锗的方法。该法简单、快速、灵敏度高、重现性好。
The determination of trace germanium in ganoderma lucidum by graphite furnace atomic absorption spectrometry was studied. The sample was decomposed with NaOH and H 2 O 2 as digestion solution. The matrix of NaOH + Ni (NO 3) 2 mixed matrix was directly used in pyrolytic coating of graphite tube Determination of trace amounts of germanium in Ganoderma lucidum drink. The method is simple, fast, sensitive and reproducible.
