多参数食品安全现场快速分析仪的应用研究——保健品中过氧化氢快速测定
Application of the Multi-Parameter Fast Food Security Analyzer-Fast Determination of Hydrogen Peroxide in Health Food
【摘要】 提出了一种用于保健钙片中过氧化氢快速测定的新方法。采用乙酸锌、亚铁氰化钾和草酸氢钾作为前处理试剂,在弱酸性介质和60℃条件下提取过氧化氢。考查了提取温度和提取时间对过氧化氢检测性能的影响。采用本方法在30分钟内即可完成对保健钙片中过氧化氢的快速定量测定。
【Abstract】 A novel method for determination of hydrogen peroxide in calcium tablets was developed. The zinc acetate, the potassium ferrocyanide and the potassium binoxalate are used as the sample preparation reagent of calcium tablets, and the hydrogen peroxide in samples can be extracted in weak-acid medium and 60℃ water bath. Various experimental param- eters such as the temperature of the water bath and the time of the extraction were studied and optimized. The analysis of each sample can be completed in 30 minutes
