A new methodology for the assessment of thiocyanate (SCN(-)) is proposed based on optical fiber (OF) detection coupled to a liquid chromatography system (LC). The developed methodology showed an adequate performance for the analysis of SCN(-) comparable to a high performance liquid chromatography with UV detector (HPLC-UV) methodology: a detection limit of 3 µg L(-1), a linear range from 4 to 400 µg L(-1), and an analytical time of less than 6 min. The OF based methodology was of compact design and easy operation. This simple system has the potential to be used as a sensing approach for SCN(-) in seawater.
提出了一种基于光纤(OF)检测与液相色谱系统(LC)联用的硫氰酸盐(SCN(-))评估新方法。所开发的方法在分析SCN(-)方面表现出与配备紫外检测器的高效液相色谱(HPLC-UV)方法相当的性能:检测限为3 µg L(-1),线性范围为4至400 µg L(-1),分析时间小于6分钟。基于光纤的方法设计紧凑且操作简便。这种简单的系统有潜力用作海水中SCN(-)的传感方法。
