中文摘要 | 發酵粉與小蘇打中銅、鐵、鉛、鎘、鈷和鎳經分離及預濃縮後,續利用原子吸收光譜法進行測定。本研究採用兩種不同的分離/預濃縮方法,分別為APDC-Chromosorb 102固相粹取法及Ce(OH)4共沉澱法。研究中特別針對小蘇打和發酵粉中主要成分對待測元素在分析時可能造成的影響進行探討。所建立的分析方法成功地應用於測定購自土耳其區域市場(Kayseri City-Turkey)小蘇打和發酵粉中的銅、鐵、鉛、鎘、鈷和鎳之成分含量(回收率高於95%)。實驗的結果顯示,這兩種預濃縮方法對同一樣品的分析結果大致頗為相符。這些金屬在小蘇打和發酵粉中的含量均低於土耳其官方的最低限量值。 |
英文摘要 | The contents of copper, iron, lead, cadmium, cobalt and nickel in baking powder and baking soda samples have been determined by atomic absorption spectrometry after separation and preconcentration. Two different separation/preconcentration methods including APDC-Chromosorb 102 solid phase extraction method and Ce(OH)4 coprecipitation method have been used for this purpose. The effects of main components of the baking soda and powder were examined. The methods were successfully applied for the determinations of Cu, Fe, Pb, Cd, Co and Ni in the baking soda and baking powder samples purchased from the local markets in Kayseri City-Turkey (recoveries greater than 95%). The results found the two preconcentration methods generally agree with each other. The levels of the analytes in the samples were below the allowed limit values given by Turkish Authorities. |
