硫化物是水质检测的一个重要参数,因其对水生生物和人体具有很高的毒性而备受关注。综述了近5 a来环境水样中硫化物的分析方法研究进展,包括光谱法(分光光度法、荧光法、电致化学发光法、电感耦合等离子体-原子发射光谱、原子吸收法、流动注射法),色谱法,以及电化学法(阴极溶出伏安法、阳极溶出伏安法、电催化氧化法、生物传感器法),指出发展高灵敏、高选择性的检测技术对于实现环境水中硫化物的现场实时检测具有重要的意义。
Sulfide is an important parameter to be monitored in water quality.It is always given to attention due to its high toxicity for aquatic organisms and human beings.The progress on analytical methods for sulfide in environmental water samples in latest five years was reviewed including spectrometry(spectrophotometry,fluorescence method,electrical induced chemiluminescence method,inductive coupled plasma-atomic emission spectrometry,and atomic absorption method,flow injection method),chromatography,and electrochemical method(cathode dissolution voltammetry,anodic dissolution voltammetry,electricity catalytic oxidation,biological sensors method).This review gives some referential values for developing more sensitive analytical methods for sulfide determination in environmental water samples.
