摘要
研究和分析了分光光度法、离子色谱法、自动顶空-气相色谱法3种测定白酒中微量氰化物的方法,比较了3种方法的线性相关性、方法稳定性和加标回收率。结果表明,所建立的自动顶空-气相色谱法方法较稳定,线性相关性较好,操作简单,结果精准,适用于白酒企业对大量样品中微量氰化物的日常检测。
The detection methods of trace cyanide in Baijiu(liquor) including spectrophotometry, ion chromatography, and automatic headspace-gas chromatography method were compared in linear correlation, stability and spiked recoveries. The analytic results suggested that, automatic headspace-gas chromatography method was more stable and had better linear correlation than the other two methods. Besides, it was simple to operate with accurate detection results. Accordingly, it was suitable for routine analysis of trace cyanide in large number of Baijiu(liquor) sam-ples in distilleries.
