介绍了一种检测废水中硫氰酸根的简便方法,即采用分光光度法,以硝酸铁为显色剂,吐温-80和丙酮为稳定剂,在438 nm波长处检测废水中的硫氰酸根含量。线性范围为2—20 mg/L,最低检出限为1 mg/L。同时探讨了非离子表面活性剂吐温-80和丙酮存在下,Fe^3＋与SCN-的显色反应条件。该法可用于直接检测工业和生活废水。

This paper describes a simple method of determination of thiocyanate content in wastewater. The thiocyanate content in wastewater was determined by Spectrophotometry in the 438nm wavelength with iron nitrate as colouring reagent and Tween-80 and acetone as stabilizer. Calibration curves are linear in the range 2--20 mg/L, Fe^3＋ with the detection limit of 1 mg/L. The conditions of colour reaction on and SCN are also investigated in the presence of non-ionic surfactant Tween-80 and acetone. This method is very ideal for the determ...
