氰化物

When the cyanide is determined by isonicotinic acidpyrazalon method, the ethyl benzoate is distilled and goes into NaOH absorption liquid with cyanide in the process of predistillation, because its boiling point is low.

在用异烟酸吡唑啉酮法对其进行氰化物测定时，由于油酯类的沸点较低，在预蒸馏过程中被蒸出和氰化物一起进入NaOH吸收液

The wastewater from gum benzion production contains benzaldehyde, cyanide, gum benzoin and ethyl benzoate. When the cyanide is determined by isonicotinic acidpyrazalon method, the ethyl benzoate is distilled and goes into NaOH absorption liquid with cyanide in the process of predistillation, because its boiling point is low. Thus the absorption liquid produces a great deal of foam and feculence.

摘要］有机化工产品安息香生产废水中含有苯甲醛、氰化物、安息香和苯甲酸乙酯，在用异烟酸吡唑啉酮法对其进行氰化物测定时，由于油酯类的沸点较低，在预蒸馏过程中被蒸出和氰化物一起进入NaOH吸收液，使得吸收液产生大量泡沫和沉淀，严重干扰后续比色测定。

The treatment of cyanide is essential for its high toxicity and popular use in many industrials.

氰化物有剧毒，生物法是目前受到日益重视的处理氰化物的有效方法之一。

In conclusion, transport and metabolism of ferrocyanide in plants is most likely to happen and phytoremediation of this iron cyanide complex in field application may be possible.

因此认为：依据亚铁氰化物在水溶液→植物→空气系统内的迁移和转化，亚铁氰化物的植物修复是可能的。

Phytotoxic efects were not found in all treatment groups,even at high doses of ferrocyanide within a 192-h exposure period.in conclusion,transport and metabolism of ferrocyanide in plants is most likely to happen and phytoremediation of this iron cyanide complex in field application may be possible.

Cyanide in water, in tissues of aerial part of plants and in air was analyzed spectrophotometrically. Results from this study indicated less than 10.85% reduction of the applied iron cyanide complex was detected in hydroponic solution in the presence of plants. Little amounts of cyanide were found in all parts of plant tissues, indicating the passage of ferrocyanide through the plants.

结果表明：(1)低浓度实验组52.99mg CN L^(-1水溶液中10.85%的亚铁氰化物被植物吸收，随着浓度的升高吸收到植物体内的亚铁氰化物的比例依次递减，但是统训学分析显示各实验组单位体重的植物吸收亚铁氰化物的量无显著性差异；(2)在植物的各个部位都能检测到微量的亚铁氰化物，表明亚铁氰化物通过植物的蒸腾作用在植物体内的迁移。

Little amounts of cyanide were found in all parts of plant tissues, indicating the passage of ferrocyanide through the plants.Mass balance studies showed that iron cyanide complex moving into plants from hydroponic solution can be metabolized during transport.

由于没有检测到在气态下的总氰化物，表明植物的蒸腾作用没有将亚铁氰化物释放到大气中；(3)尽管植物吸收到体内的亚铁氰化物足有限的，但物质平衡实验表明其在植物体内迁移的过程中超过96％的郜能被植物有效转化；(4)所用的4种亚铁氰化物浓度在192 h内没有对柳树产生毒性作用。

Cassava was the main crop rich in starch, but with high content of the toxic cyanogenic glucosides linamarin and lotaustralin in all tissues, and cytochrome P450 gene catalyzing the biosynthesis of cyanogenic glucoside.

亚麻苦苷和百脉根甙等氰化物是木薯块茎、茎叶等组织或器官中的剧毒物质，细胞色素p450是调控氰化物生物合成的关键酶基因，克隆有关酶基因对于理解木薯氰化物代谢和通过转基因对木薯氰化物的改良具有重要意义。

In SART law (vulcanization - acidification - return - condense) in, add NaHS to make the prussiate that is united in wedlock with content of cupreous cyanogen complexing is released, with precipitation copper, and be below weak acidity condition gas of HCN of prussiate translate into, in making its return soak loop with free prussiate form.

在SART法(硫化-酸化-返回-浓缩)中，添加NaHS使和铜氰络合物结合的氰化物释放出来，以沉淀铜，并且在弱酸性条件下将氰化物转化为HCN气体，使其以游离氰化物形式返回到浸出回路中。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
