氰化物是环境监测和化工分析中的重要分析指标之一。用化学法测定水中的氰,操作繁琐、费时。氰离子选择性电极法,最早见于Rechnitz等人的报导,方法简单、快速。在我国,近年来,也开始了试制和应用的研究。本实验对应用国产氰离子选择性电极测定地面水、含氰工业废水中的氰的方法作一初步探讨。 (一)主要仪器和试剂 1.pHs-2型精密酸度计(上海第二分析仪器厂出品)。 2.GST-76-01型固态膜氰离子选择
Cyanide is one of the most important analytical indicators in environmental monitoring and chemical analysis. Determination of cyanide in water by chemical methods, cumbersome operation, time-consuming. Cyanide ion selective electrode method, first seen in Rechnitz et al., The method is simple and fast. In our country, in recent years, we have also started trial and applied research. In this experiment, a method for the determination of cyanide in surface water and cyanide-containing industrial wastewater by domestic cyanide selective electrode was briefly discussed. (A) of the main instruments and reagents 1.pHs-2-type precision acid meter (Shanghai Second Analytical Instrument Factory produced). 2.GST-76-01 type solid-state membrane cyanide ion selection
