| 中文摘要 | 本研究探討以石墨爐式原子吸收光譜儀直接測量酒中鉛、銅及鎘之含量。將檢體 以 0.5% 硝酸溶液稀釋至酒精濃度 5% 以下，添加 0.5% 磷酸二氫鉀溶液為修飾劑，以偏極 化茲曼石墨爐式原子吸收光譜儀直接測定其吸光度，由標準曲線計算其含量。偵測極限為鉛 0.5ng/mL, 銅 0.5ng/mL 及鎘 0.05ng/mL。 添加鉛 10,20,30ng/mL, 銅 10,20,30ng/mL 及 鎘 1.0，2.0，3.0ng/mL 於啤酒、葡萄酒及高梁酒中， 鉛之回收率於啤酒為 95.3-97.9%， 於葡萄酒為 94.2-99.1%， 於高梁酒為 95.1-98.9%: 銅之回收率於啤酒為 97.1-98.3%，於 葡萄酒為 97.4-99.5%， 於高梁酒為 97.5-99.1%; 鎘之回收率於啤酒為 98.1-99.5%，於葡 萄酒為 98.3-99.4%，於高梁酒為 97.5-99.7 %。以此法分析國產酒34件及進口酒45件，共 計 79 件。 國產酒檢出含鉛 15 件，平均含量 23.41ng/mL，檢出範圍 2.7-63.9ng/mL，進 口酒檢出 16 件， 平均含量 13.02ng/mL，檢出範圍 0.9-49.7ng/mL。 國產酒檢出含銅 23 件， 平均含量 79.31 ng/mL， 檢出範圍 5.3-503.0ng/mL ．進口酒檢出 41 件，平均含量 64.42ng/mL，檢出範圍 2.9-445.0ng/mL。 國產酒檢出含鎘 4 件，平均含量 3.4ng/mL，檢 出範圍 2.5-5.0ng/wL，進口酒檢出 9 件，平均含量 0.9ng/mL。檢出範圍 0.2-2.3ng/mL。 |
| 英文摘要 | A quick, easy method for determinationof lead, copper and cadmium in alcoholic beverage was developed. The method uses a polarized Zeeman graphite furnace atomic absorption spectrophotometer (GFAAS) and pyrolytic graphite tube. Ammonium dihydrogen phosphate was used as a matrix modifier. Alcoholic beverages were diluted to a concentration of less than 5% alcohol with 0.5% nitric acid and were analyzed directly. The estimated detection limits were 0.5 ng Pb/mL, 0.5 ng Cu/mL and 0.05 ng Cd/mL. Recovery studies were performed using beer, grape wine and kao liang liguor. fortified with 10, 20 and 30 ng PbfmL, 10, 20 and 30 ng Cu/mL and 1.0, 2.0 and 3.0 ng Cd/mL, respectively. Recoveries of lead in beer were in the range of 95.3-97.9%, in grape wine were in the range of 94.2- 99.1% and in kao liang liquor were in the range of 95.1-98.9%. Recoveries of copper in beer were in the range of 97.1-98.3%, in grape wine were in the range of 97.4-99.5% and in kao liang liquor were in the range of 97.5-99.1%. Recoveries of cadmium in beer were in the range of 98.1-99.5%, in grape wine were in the range of 98.3-99.4% and in kao liang liquor were in the range of 97.5-99.7%. Sev- enty-nine samples of alcoholic beverages were analyzed using GFAAS. Results showed that the contents of heavy metals in the domestic products were 2.7-63.9 ng Pb/mL (15 samples), 5.3-503.0 ng Cu/mL (23 samples) and 2.5-5.0 ng Cd/mL (4 samples). In the imported products, they were 0.9-49.7 ng PbfmL (16 samples), 2.9-445.0 ng Cu/mL (41 samples) and 0.2-2.3 ng Cd/mL (9 samples). |
