摘　　要：在水体污染检测工作中,硫化物的含量是一项重要的指标。就相关检测技术而言,碘量法引起具有高效、简便、成本低等特征,得到了广泛的应用。然而,碘量法仅能够对1 mg/lL的中低浓度硫化物进行检测,因此其应用范围不广。分析碘量法的应用原理,之后研究碘量法检测水中硫化物的实验方法,并指出其中的不足,提供相关对策,以供同行业人员进行参考。In the detection of water pollution,the content of sulfides is an important indicator.In terms of relevant detection techniques,the iodine method has been widely used due to its high efficiency,simplicity,and low cost.However,the iodometric method can only detect low to medium concentrations of sulfides at 1 mg/l/L,so its application range is not wide.Firstly,this paper analyzes the application principle of iodimetry,then studies the experimental method of iodimetry for detecting sulfides in water,points out its shortcomings,and provides relevant countermeasures for reference by professionals in the same industry.
