摘要
氰化物都具有或大或小的毒性,对人、畜、水生动物生命存在威胁,此外氰还能造成农作物减产。生活饮用水卫生标准将其作为一个重要的检测项目并对含量有明确的限定。由于氰化物在一般水体中含量极微,所以定量检测的每一个环节都存在着严重影响结果的可能性。文章重点阐述总氰经典测定方法中影响方法准确性的因素以及消除这些因素的办法。
Cyanides, with different toxicity,are threatening man, livestock and aquatic. Moreover, they can reduce the output of the crop. It is an important detecting item and sets a clear density limit in the standards of drinking water. Every step of the cyanides quantifying examination has the potentiality to influence the accuracy result seriously because of the slighted concentration in water. The paper elaborates the primarily factors which may influence accuracy in the classical measuring method for the total cyanide and the ways to avoid these interferential factors.
