用连续流动分析仪总氮通道测六价铬的探讨

摘要

将已有的荷兰Skalar连续流动分析仪中测定总氮的模块进行简单改造,用于测定水体中六价铬.结果显示,测定结果与国标方法无显著差异.本方法既可以利用现代化仪器高效快速的优点,又为单位或企业节约了二次采购仪器的成本.%The existing module for determining the total nitrogen in the Skalar continuous flow analyzer made in Netherland has been modified simply,and applied to the determination of hexavalent chromium in water bodies. It is shown that the determination results do not have any significant differences with that of international standard methods. It can not only make use of efficient and fast advantages of the modern instrument ,but also has saved the costs of making the second purchase of equipment for units or enterprises.
