| 摘 要： | 建立了马铃薯及其淀粉中氰化物离子色谱的检测方法。样品经超声、冷冻离心、通过在线过滤处理后直接用离子色谱进行检测。检出限为0.054 mg/L,氰化物的线性范围为0.136～2.72 mg/L;加标回收率为85%～93%;相对标准偏差(RSD)为1.2%,可以满足氰化物检测的要求。

| Abstract: | The hydro cyanic acid exists in the potato and the starch,has the fierce toxicity,to the human,the livestock creates the severe impairment.A new method was developed for the determination of cyanide in potato and its starch by ion chromatography(IC),the samples were refrigerated and centrifuged,after processing by the "Inline" were detected by ion chromatography,the calibration curves were linear in range of 0.136～2.72 mg/L.The spiked recoveries were in the range of 85%～93%,the detection limit of cyanide was 0.054 mg/L,and the relative standard deviation was 1.2%,As a conclusion,it is applicable for the determination of cyanide in potato and its starch. |
