目的：建立石墨炉原子吸收光谱法测定药用辅料胆固醇中镍的含量。方法：样品经硝酸-过氧化氢微波消解后用0.5％稀硝酸稀释，采用石墨炉原子吸收光谱法，以塞曼背景校正，标准曲线法测定。结果：该方法测定胆固醇中镍含量的线性范围20～100 mg · L -1，r＝0.9973；检出限为0.4 mg · L -1；平均加样回收率为102.6％（n＝9），RSD为3.9％。结论：方法快速、准确、可靠，适用于药用辅料胆固醇中镍含量的测定。
目的：建立石墨爐原子吸收光譜法測定藥用輔料膽固醇中鎳的含量。方法：樣品經硝痠-過氧化氫微波消解後用0.5％稀硝痠稀釋，採用石墨爐原子吸收光譜法，以塞曼揹景校正，標準麯線法測定。結果：該方法測定膽固醇中鎳含量的線性範圍20～100 mg · L -1，r＝0.9973；檢齣限為0.4 mg · L -1；平均加樣迴收率為102.6％（n＝9），RSD為3.9％。結論：方法快速、準確、可靠，適用于藥用輔料膽固醇中鎳含量的測定。

A method (graphite furnace atomic absorption spectrophotometry ,GFAAS ) for determina-tion of nickel in cholesterol was developed .The sample digested by microwave in nitric acid-hydrogen per-oxide and diluted by 0 .5% nitric acid .GFASS was used to analyze nickel in the sample ,corrected by Zee-man background and calculated by standard curve .The linear range was 20-100g · L -1 (r=0 .9973) .The detection limit of nickel was 0 .4mg · L -1 ,the average recovery was 102 .6% (n=9) ,and the relative stand-ard deviation(RSD) was 3 .9% .The method is rapid ,accurate ,reliable and suitable to determinen the nick-el in cholesterol .
