目前,蒸馏酒中氰化物的测定,多采用异烟酸-吡唑酮法、吡啶-巴比妥酸法以及吡啶盐酸联苯胺比色法,它们操作较繁,所用试剂多,并且吡啶有毒有恶臭。酒样中乙醇含量对吸光度影响很大,要求标准系列中含醇量与样品一致,这点很难作到,致使测定具有一定的误差。本文利用Hg~(2+)与氰化物形成稳定的络合物以促使Hg~_2(2+)歧化,释放出Hg~0,于253.7nm处用冷原子吸收光谱法测定汞量,间接求得氰化物含量,从而避免了酒 Currently, the determination of cyanide in distilled spirits, and more use of isonicotinic acid - pyrazolone method, pyridine - barbituric acid method and pyridine benzidine hydrochloride colorimetric method, they are more complex, the reagents used, and pyridine toxic stench. Ethanol content of wine samples on the absorbance of a great impact on the standard series requires the same amount of alcohol and the sample is difficult to do, resulting in the determination of a certain error. In this paper, Hg ~ (2+) forms a stable complex with cyanide to promote the disproportionation of Hg ~ _2 (2+), releasing Hg ~ 0. The mercury content is determined by cold atomic absorption spectrometry at 253.7nm. Cyanide content, thus avoiding the wine
