摘要
改进了用于水中硫化物测定的酸化－吹取－吸收预处理方法，对水样预处理条件及校准曲线的制作进行了详细试验。该方法具有吹取完全、吸收完全、操作简单、准确度高的优点，适用于水和废水中微量硫化物的测定。
A pretreatment method of acidification air stripping absorption for determination of sulfide in water has been improved.The conditions for water sample pretreatment were tested in detail and the calibration curves were made.The method is characterized by stripping and absorbing completely,simple operation and high precision.It is suitable for the determination of trace amount of sulfide in water and wastewater.
