摘要
当氰化物测定值小于分析方法的最低检出限时，通常按1／2最低检出限报告检出结果。为了区别在检出下限附近的样品与完全不含氰的样品，本实验探讨通过控制接收馏出液体积的方法，以降低时原始样品的检出限．并对低于1／2最低检出限的样品的浓度值进行必要的校正。
When cyanide measured value is smaller than the minimum detecting limit of analysis methods ,measured result usually is recorded by one-half the minimum detecting limit. To point up the distinction between the sample nearby detectinginferior limit and one with no cyanide, the experiment discussed the method of lowering detecting limit of primary sample through controlling volume of receiving distillate,and corrected the sample concentration when measured valuewas smaller than one-half of the minimum detecting limit.
