亚麻籽中氰化物定性定量方法的研究

Study on qualitative and quantitative methods of cyanide in flaxseed

建立测定亚麻籽中氰化物的定性定量方法。结果表明,改进的异烟酸-吡唑啉酮比色法能进行亚麻籽氰化物的测定,检测方法具有很强的线性相关性,R2=0.9986,加标回收率93.08%～95.65%,相对标准偏差<5%。本方法灵敏,准确可靠,重现性好,测定的结果可靠。

Objective to establish a qualitative and quantitative methods of cyanide in flaxseed. Results showed that modified isonicotine acid-pyrazolone colormetric method was possible to measure cyanide content of flaxseed, with very strong linear relevance （R^2 = 0.9986） and high returns-ratio of additive sample （93.08%-95.65%） as well as small relative standard deviation （less than 5%）. The methods were sensitive, accurate, reliable, and suitable for the detection of cyanide.
