摘　　要：氰化物是一类剧毒物质,危害极大,可在数秒之内使人出现中毒症状,急性中毒可导致呼吸衰竭,致人死亡,慢性中毒会导致人器官或组织产生病变。美国环保署在饮用水中设定的游离氰化物的最大污染物浓度为200μg/L;欧盟的设定的最大浓度为不超过50μg/L,我国规定不得超过0.05 mg/L。为准确掌握水中氰化物的含量,提升水处理技术,确保居民生产生活用水安全,快捷、经济、准确有效的检测技术显得尤为重要。Cyanide is a kind of highly toxic substance with great harm.It can cause poisoning symptoms within a few seconds.Acute poisoning can lead to respiratory failure and death.Chronic poisoning can lead to pathological changes in human organs or tissues.The maximum pollutant concentration of free cyanide set by the Environment Protection Agency(EPA)in drinking water is 200μg/L;the average lower limit for the EU is 50μg/L;China's regulations shall not exceed 0.05 mg/L.In order to accurately grasp the cyanide content in water,improve water treatment technology,and ensure the safety of residents'production and domestic water,rapid,economic,accurate and effective detection technology is particularly important.This paper describes the various technical characteristics and applications of cyanide analysis methods in water at present.
