编辑同志: 贵刊1982年第一期发表吉秉勋同志“合金中镁、镍、铅的测定—用丙酮氰醇(C_4H_7NO)代替氰化钾作掩蔽剂”一文,曾引起我们的兴趣。因为氰化钾为极毒品,寻找同样有效而无毒或低毒的代用品是很有意义的工作。但该文只谈到氰化钾是极毒品而没有正面谈到丙酮氰醇的毒性问题,为此我们查阅了有关资料,发现丙酮氰醇与氰化钾均为极毒品。例如“全国化学试剂产品目录(483页,化学工业出版社,1979年);”“分析化学手册第一分册”(杭州大学化学系分析化学教研室编,308页,化学工业出版
Editor’s commentary: Your first issue of 1982, Comrade Ji Bingxun, “Determination of magnesium, nickel and lead in alloys - Cyanogen with acetone cyanohydrin (C_4H_7NO) as masking agent” has attracted our interest. Because potassium cyanide is a highly toxic product, finding workplaces that are equally effective, nontoxic or low toxic is a significant undertaking. However, the article only talked about potassium cyanide is a very toxic drugs without positive talk about the toxicity of acetone cyanohydrin, for which we reviewed the relevant information and found that acetone cyanohydrin and potassium cyanide are extremely toxic. For example, “National Chemical Reagent Catalog (483 pages, Chemical Industry Press, 1979);” “Analytical Chemistry Manual Volume I” (Department of Chemistry, Hangzhou University Department of Analytical Chemistry, 308 pages, published by the Chemical Industry
