标准范围

该方法基于称量试样，在水中溶解，转移到一个纳氏比色瓶中，用移液管将体积的硫化物标准溶液移到第二个纳氏比色瓶中，添加碱性铅溶液，用水补充，彻底混合，并比较两种溶液的颜色和透明度。

The method is based on weighing a test portion, dissolution in water, transfer to one of the Nessler colour-comparison cylinders, pipetting the volume of sulfide standard into the second Nessler colour-comparison cylinder, addition of alkaline lead solution, making up with water, mixing thoroughly, and comparing the colour and clarity of the two solutions.
